OpenAFS for Windows 1.3.8400 Installation Notes --------------------------------------------- The OpenAFS for Windows product was very poorly maintained throughout the 1.2.x release cycle. While the Unix version was being enhanced and its quality was improving the Windows version stagnated. The IBM AFS 3.6 product was not designed for the Windows 2000/XP/2003 operating system nor was it architected with highly disconnected environments in mind. The 1.3.x series of releases not only fixes a large number of bugs in the 1.2 series but also attempts to enhance the functionality of the product to better fit the usage model of today's users. Several items standout. 0. The default AFSCache file is approximately 100MB. This space is required in addition to the space allocated to OpenAFS binaries. 1. The Kerberos 4 infrastructure on which the 1.2 series is reliant is no longer secure. Cross-realm Kerberos is very important in the AFS context and most sites have or are migrating to Kerberos 5 environments. The 1.3 series integrates with the MIT Kerberos for Windows 2.6.x product to provide Kerberos 5 functionality including the ability to auto-renew credentials and obtain single sign-on capabilities with the Microsoft Windows Kerberos Logon Service. As of 1.3.65, the OpenAFS client will directly use Kerberos 5 tickets as tokens if KFW is installed. The client requires that all of the AFS Servers with which it communicates support the use of Kerberos 5 tickets as tokens (aka 2b tokens). This means that all of the AFS servers must be running OpenAFS release 1.2.8 or higher. Transarc servers do not support Kerberos 5 tickets as tokens. When using a Microsoft Windows Active Directory as the KDC which issues the service ticket for the AFS cell there are two things to consider. First, the Kerberos 5 tickets issued by Active Directory can be quite large when compared to tickets issued by a traditional KDC due to the incorporation of authorization data in the PAC. If this is your situation you either must modify your 1.2.x servers to support tokens larger than a few hundred bytes; or install the 1.3.64 or higher release on your servers. Second, Windows 2003 Active Directory will issue service tickets utilizing the DES-CBC-MD5 enctype. OpenAFS releases older than 1.3.64 will not properly support this enctype. 2. The AFS Client Service does not provide robust behavior in an environment with a plug-n-play network environment. Changes to the number of network adapters or the assigned IP addresses will cause the service to panic. The recommended work around for this problem is to install the Microsoft Loopback Adapter on the machine. When the MLA is installed with a static IP address the AFS Client Service will bind only to the loopback and not be affected by changes to state of other network adapters installed on the system. Starting in the 1.3.65 release the installers provided by OpenAFS.org will install the Microsoft Loopback Adapter for you with a name of "AFS" and a pre-assigned IP address in the 10.x.x.x range. One of the benefits of using the MLA is that the NETBIOS names used for the AFS Client's SMB server do not have to be published on any adapter other than the MLA. This means that the names no longer need to be unique. When the MLA is in use, the NETBIOS name associated with the AFS Client Service is simply "AFS". When the MLA is not in use the NETBIOS name is "MACHINE-AFS". When the MLA is installed, UNC paths of the form \\AFS\cellname\path may be used. The MLA is installed with a binding to "Client for Microsoft Networks" but not to "File and Printer Sharing for Microsoft Networks". If you fail to bind "Client Microsoft Networks" you will not be able to access the AFS Client Service when the machine is disconnect from the network. If you bind "File and Printer Sharing ..." there will be a conflict between the name "AFS" and the name of the machine on the published IP Address. This will result in a failure to be able to access files in AFS. The "NET VIEW" command will return a "System Error 52" message when this conflict exists. To correct the problem: * stop the AFS Client Service * bind the "Client for Microsoft Networks" to the MLA * unbind "File and Printer Sharing for Microsoft Networks" from the MLA * Disable and then Enable the MLA * start the AFS Client Service 3. Traditionally, when the AFS Client Service starts it must be able to access the "root.afs" volume of the default cell. The "root.afs" volume contains a set of read-only and read-write mount points to the "root.cell" volumes of various cells the administrator of the default cell believes should be accessible. If the "root.afs" volume is inaccessible when the client service is started, the service will panic. Since many users now use laptops or otherwise operate in disconnected environments in which a VPN may be needed to access the cell's servers, it is often the case that the "root.afs" volume for the default cell is not reachable and the AFS Client Service will not successfully start. The OpenAFS Client Service now supports a fake "root.afs" volume which is dynamically constructed when the service starts. This mode is called Freelance mode. Freelance mode is turned on by default. The contents of the fake "root.afs" volume are constructed dynamically as cells are accessed. When the fake "root.afs" volume is constructed it will only contain two mount points: a read-only and read-write mount point used to access the "root.cell" volume of the default AFS cell. Any attempt to access a valid cell name will automatically result in a new mount point being created in the fake "root.afs" volume. If the cellname begins with a "." the mount point will be read-write; otherwise the mount point will be read-only. These mount points are preserved in the registry at key: HKLM\SOFTWARE\OpenAFS\Client\Freelance Additional mount points may be manually created using the "fs mkmount" command. Mount points may be removed using the "fs rmmount" command. >fs mkmount \\AFS\all\athena.mit.edu root.cell athena.mit.edu >fs mkmount \\AFS\all\.athena.mit.edu root.cell athena.mit.edu -rw >fs rmmount \\AFS\all\athena.mit.edu >fs rmmount \\AFS\all\.athena.mit.edu Beginning in 1.3.74, the Freelance fake root.afs volume will support the creation of symlinks. >symlink make \\afs\all\link \\afs\all\athena.mit.edu\user\j\a\jaltman >symlink list \\afs\all\link '\\afs\all\link' is a symlink to 'athena.mit.edu\user\j\a\jaltman' >symlink rm \\afs\all\link The symlinks are stored in the registry at: HKLM\SOFTWARE\OpenAFS\Client\Freelance\Symlinks 4. The OpenAFS for Windows client will use AFSDB DNS records to discover cell information when it is not located in the local CellServDB file (\Program Files\OpenAFS\Client\CellServDB). 5. OpenAFS for Windows 1.3.72 only supports Windows 2000, Windows XP, and Windows 2003. Windows NT 4.0 and the entire Windows 9x/Me line are no longer supported. Older releases of OpenAFS are available for download if those operating systems must be supported. The last version with support for Win9x is 1.2.2b. The last version with support for Windows NT 4.0 is 1.2.10. 6. OpenAFS for Windows installs a WinLogon Network Provider to provide Integrated Logon (Single Sign-on) functionality. Integrated Logon can be used when the Windows username and password match the username and password associated with the default cell's Kerberos realm. For example, if the windows username is "jaltman" and the default cell is "athena.mit.edu", then Integrated Logon can be successfully used if the windows password matches the password used for the Kerberos principal "jaltman@ATHENA.MIT.EDU". Integrated Logon is required if you desire the ability to store roaming user profiles within the AFS file system. OpenAFS does not provide tools for synchronizing the Windows and Kerberos user accounts and passwords. If KFW is installed, the Integrated Logon will use Kerberos 5 to obtain tokens. Otherwise, Kerberos 4 is used. There is a High Security mode for use with Integrated Logon when multiple users will share a single machine. There are known problems with this mode. In particular, if you are using this mode it is crucial that new AFS tokens not be obtained after the logon session starts except via the AFS Systray tool as started by the AFS Network Provider. If the AFS Systray tool is stopped you must log off to obtain new tokens. Do not use external tools such as "aklog.exe" if High Security mode is turned on. As of 1.3.70, OpenAFS supports Authenticated SMB connections which removes the need for High Security mode. DO NOT USE IT!!!!! What Integrated Logon does not do: (a) Integrated Logon does not have the ability to obtain Kerberos 5 tickets for use during the Windows Session. At the current time there is no mechanism by which a Kerberos 5 CCAPI credentials cache can be constructed during the logon process such that it will exist in the user's logon session. (b) Integrated Logon does not have the ability to cache the user's username and password for the purpose of obtaining tokens if the Kerberos KDC is inaccessible at logon time. 7. The AFS Systray tool (afscreds.exe) supports several command line options: -A = autoinit -E = force existing afscreds to exit -I = install startup shortcut -M = renew drive maps -N = ip address change detection -Q = quiet mode. do not display start service dialog if afsd_service is not already running -S = show tokens dialog on startup -U = uninstall startup shortcut -X = test and do map share -Z = unmap drives -: = magic parameter for high security mode autoinit will result in automated attempts to acquire AFS tokens when afscreds.exe is started. afscreds.exe will attempt to utilize tickets stored in the MSLSA credentials cache; any existing CCAPI credentials cache; and finally display an Obtain Tokens dialog to the user. When used in combination with ip address change detection, afscreds.exe will attempt to acquire AFS tokens whenever the IP address list changes and the Kerberos KDC is accessible. The renew drive maps option is used to ensure that the user drive maps constructed via the AFS tools (not NET USE) are re-constructed each time afscreds.exe is started. By default afscreds.exe is configured by the OpenAFS.org installers to use -A -N -M -Q as startup options. Currently, there is no UI to change this selection after install time although these options may be altered via the registry either per machine or per user. See AfscredsShortcutParams in registry.txt. 8. As of 1.3.71, the OpenAFS for Windows client supports a local Windows authorization group called "AFS Client Admins". This group is used in place of the "Administrators" group to determine which users are allowed to modify the AFS Client Service configuration via either afs_config.exe or fs.exe. For example, the following fs.exe commands are now restricted to members of the "AFS Client Admin" group: - checkservers with a non-zero timer value - setcachesize - newcell - sysname with a new sysname list - exportafs - setcell - setserverprefs - storebehind - setcrypt - cscpolicy - trace Setting the default sysname for a machine should be done via the registry and not via "fs sysname". The local "SYSTEM" account is always a member of the "AFS Client Admin" group. The initial membership of the "AFS Client Admin" group when created by the installer is equivalent to the local "Administrators" group. 9. The AFS Client should support UNC paths everywhere. Power users that make extensive use of the command line shell, cmd.exe, might want to consider using JP Software's 4NT command processor. Unlike cmd.exe, 4NT does fully support UNC paths and can use a UNC path as the default device. 10. The AFS Client ships with its own version of aklog.exe which should be used in preference to those obtained by third party sources. The OpenAFS aklog.exe supports Kerberos 5 as well as the ability to auto-generate pts IDs for user's obtaining tokens to foreign cells. Usage: aklog [-d] [[-cell | -c] cell [-k krb_realm]] [[-p | -path] pathname] [-noprdb] [-force] [-5 | -4] -d gives debugging information. krb_realm is the kerberos realm of a cell. pathname is the name of a directory to which you wish to authenticate. -noprdb means don't try to determine AFS ID. -5 or -4 selects whether to use Kerberos V or Kerberos IV. (default is Kerberos V) No commandline arguments means authenticate to the local cell. 11. The AFS Server functionality provided with OpenAFS 1.3.72 might work but should be considered highly experimental. It has not been thoroughly tested. Any data which would cause pain if lost should not be stored in an OpenAFS Server on Windows. A few notes on the usage of the AFS Client Service if it is going to be used with the OpenAFS AFS Server: (a) When the AFS Server is installed Freelance mode must be turned off. (b) The AFS Server and related tools only support the built in kaserver (Kerberos IV). If the AFS Server is being used, MIT Kerberos for Windows should not be used. 12. The OpenAFS for Windows installers now include Symbol information which should be installed if you are experiencing problems and need to send crash reports. This is true in both the release and the debug versions of the installers. The differences between the release and debug versions are whether or not the binaries were compiled with optimization; whether the debug symbols are installed by default; and whether additional debug statements were compiled into the binaries. 13. OpenAFS for Windows does not support files larger than 2GB. 14. Local RPC is used as the default RPC mechanism for setting tokens. TCP RPC is required to be installed and is used for debugging and other functions. 15. OpenAFS for Windows automatically open ports in the Windows Internet Connection Firewall. 16. The OpenAFS for Windows installer by default activates a weak form of encrypted data transfer between the AFS client and the AFS servers. This is often referred to as "fcrypt" mode. 17. OpenAFS 1.3.71 adds support for authenticated SMB connections using either NTLM or GSS SPNEGO (NTLM, Kerberos 5, ...). In previous versions of OpenAFS the SMB connections were unauthenticated which left open the door for several security holes which could be used to obtain access to the use of other user's tokens on shared machines. With the introduction of authenticated SMB connections the so called High Security mode should no longer be used. When GSS SPNEGO results in a Kerberos 5 authentication, the Windows SMB client will attempt to retrieve service tickets for "cifs/afs@REALM" (if the loopback adapter is in use) or "cifs/machine-afs@REALM" (if the loopback adapter is not being used). It is extremely important that this service principal not exist in the KDC database. If the request for this ticket fails, a subsequent request for "cifs/HOST$@REALM" will be issued. This service principal should exist in the KDC database. The key associated with this service principal must match the key assigned to "host/machine@REALM". If the local machine is part of a Windows Domain this will all be taken care of for you. If the local machine is using a non-MS KDC for authentication, then your KDC administrator will have to add these service principals to the list of principals to be maintained for each host. 18. As of 1.3.70, INI files are no longer used for the storage of AFS configuration data. No longer are there any AFS related files stored in the %WINDIR% directory. The CellServDB file is no longer called "afsdsbmt.ini" and it is stored in the OpenAFS\Client directory. The afs_freelance.ini and afsdsbmt.ini file data has been moved to the registry. IMPORTANT: while the CellServDB file location and freelance mountpoint data will be automatically migrated; there is no mechanism for automatic migration of Submounts, Drive Mappings, Active Maps, and CSCPolicy data. 19. As of 1.3.70, the OpenAFS Client is compatible with Windows XP SP2 and Windows 2003 SP1. The Internet Connection Firewall will be automatically adjusted to allow the receipt of incoming callback messages from the AFS file server. In addition, the appropriate Back Connection entries are added to the registry to allow SMB authentication to be performed across the loopback connection. 20. As of 1.3.70, the OpenAFS Client Service supports the CIFS Remote Admin Protocol which provides browsing of server and share information. This significantly enhances the interoperability of AFS volumes within the Explorer Shell and Microsoft Office applications. 21. OpenAFS will now automatically forget a user's tokens upon Logoff unless the user's profile was loaded from an AFS volume. In this situation there is no mechanism to determine when the profile has been successfully written back to the network. It is therefore unsafe to release the user's tokens. Whether or not the profile has been loaded from the registry can be determined for Local Accounts, Active Directory accounts and NT4 accounts. 22. Terminal Server installations. When installing under Terminal Server, you must execute the NSIS installer (.exe) from within the Add/Remove Programs Control Panel. Failure to do so will result in AFS not running properly. The AFS Server should not be installed on a machine with Terminal Server installed. 23. AFS is a Unix native file system. As such the OpenAFS client attempts to treat the files stored in AFS as they would be on Unix. File and directory names beginning with a "." are automatically given the Hidden attribute so they will not normally be displayed. 24. Some organizations which have AFS cell names and Kerberos realm names which differ by more then just lower and upper case rely on a modification to krb524d which maps a Kerberos 5 ticket from realm FOO to a Kerberos 4 ticket in realm BAR. This allows user@FOO to appear to be user@bar for the purposes of accessing the AFS cell. As of OpenAFS 1.2.8, support was added to allow the immediate use of Kerberos 5 tickets as AFS (2b) tokens. This is the first building block necessary to break away from the limitations of Kerberos 4 with AFS. By using Kerberos 5 directly we avoid the security holes inherent in Kerberos 4 cross-realm. We also gain access to cryptographically stronger algorithms for authentication and encryption. Another reason for using Kerberos 5 directly is because the krb524 service runs on a port (4444) which has become increasingly blocked by ISPs. The port was used to spread a worm which attacked Microsoft Windows in the summer of 2003. When the port is blocked users find that they are unable to authenticate. Replacing the Kerberos 4 ticket with a Kerberos 5 ticket is a win in all situations except when the cell name does not match the realm name and the principal names placed into the ACLs are not the principal names from the Kerberos 5 ticket. To support this transition, OpenAFS for Windows in 1.3.72 adds a new registry value to force the use of krb524d. However, the availability of this option should only be used by individuals until such time as their organizations can provide a more permanent solution. 25. The Status Cache (AFS Config Control Panel: Advanced Page) is defined to have a maximum number of entries. Each entry represents a single file or directory entry accessed within the AFS file system. When the maximum number of entries are allocated, entries will begin to be reused according to a least recently used (LRU) algorithm. If the number of files or directories being accessed repeatedly by your applications is greater then the maximum number of entries, your host will begin to experience thrashing of the Status Cache and all requests will result in network operations. If you are experiencing poor performance you might want to increase the maximum number of Status Cache entries. Each entry requires approximately 1.2K. Note that the default number of Status Cache entries was increased to 10,000 starting in 1.3.80. 26. "Netbios over TCP/IP" must be active on the machine in order for communication with the AFS Client Service to succeed. If "Netbios over TCP/IP" is disabled on the machine, then communication with the AFS Client Service will be impossible. 27. The AFS Client Service and related binaries are digitally signed by "Secure Endpoints Inc." beginning with the 1.3.7400 release of OpenAFS for Windows. Starting in the 1.3.7500 release, the AFS Client Service will perform a run-time verification check to ensure that all AFS related DLLs loaded by the service match the same file version number and were signed by the same entity. This check has been added to prevent the stability problems caused by more then one version of AFS being installed on a machine at the same time. Many hours of support time have been wasted tracking down problems caused by the mixture of files from different releases. The registry.txt file documents the "VerifyServiceSignature" registry value which can be used to disable the signature check. The file version check cannot be disabled. 28. The maximum cache size is approximately 1.3GB. This is the largest contiguous block of memory in the 2GB process address space which can be used for the memory mapped file. Due to fragmentation of the process spaced caused by the digital signature verification code, any attempt to specify a cache size greater then 700MB will result in the automatic disabling of the signature check. 29. OpenAFS for Windows implements an SMB server which is used as a gateway to the AFS filesystem. Because of the use of SMB, Windows stores all files into AFS using the OEM code pages such as CP437 (United States) or CP850 (Western Europe). These code pages are incompatible with the ISO Latin-1 character set typically used as a default on Unix systems in both the United States and Western Europe. Filenames stored by OpenAFS for Windows are therefore unreadable on Unix systems if they include any of the following characters: [Ç] 128 08/00 200 80 C cedilla [ü] 129 08/01 201 81 u diaeresis [é] 130 08/02 202 82 e acute [â] 131 08/03 203 83 a circumflex [ä] 132 08/04 204 84 a diaeresis [à] 133 08/05 205 85 a grave [å] 134 08/06 206 86 a ring [ç] 135 08/07 207 87 c cedilla [ê] 136 08/08 210 88 e circumflex [ë] 137 08/09 211 89 e diaeresis [è] 138 08/10 212 8A e grave [ï] 139 08/11 213 8B i diaeresis [î] 140 08/12 214 8C i circumflex [ì] 141 08/13 215 8D i grave [Ä] 142 08/14 216 8E A diaeresis [Å] 143 08/15 217 8F A ring [É] 144 09/00 220 90 E acute [æ] 145 09/01 221 91 ae diphthong [Æ] 146 09/02 222 92 AE diphthong [ô] 147 09/03 223 93 o circumflex [ö] 148 09/04 224 94 o diaeresis [ò] 149 09/05 225 95 o grave [û] 150 09/06 226 96 u circumflex [ù] 151 09/07 227 97 u grave [ÿ] 152 09/08 230 98 y diaeresis [Ö] 153 09/09 231 99 O diaeresis [Ü] 154 09/10 232 9A U diaeresis [ø] 155 09/11 233 9B o slash [£] 156 09/12 234 9C Pound sterling sign [Ø] 157 09/13 235 9D O slash [×] 158 09/14 236 9E Multiplication sign [ƒ] 159 09/15 237 9F Florin sign As of 1.3.75, a new registry value, HKLM\SOFTWARE\OpenAFS\Client "StoreAnsiFilenames" can be set to instruct OpenAFS for Windows to store filenames using the ANSI Code Page instead of the OEM Code Page. The ANSI Code Page is a compatible superset of Latin-1. This setting is not the default setting because making this change would prevent OpenAFS for Windows from being able to access filenames containing the above characters which were created without this setting. 30. There is a known issue with storing Windows Roaming Profiles when the profile contains either directories or files with names which cannot be represented in the local OEM character set. In this case, attempts to write the profile back to AFS will fail. OpenAFS for Windows does not currently support UNICODE. To avoid this problem some sites run logoff scripts (assigned by group policy) which rename all files to use only the supported characters for the locale. 31. As of 1.3.80 the AFS Cache file is stored by default at %TEMP%\AFSCache in a persistent file marked with the Hidden and System attributes. The persistent nature of the data stored in the cache file improves the performance of OpenAFS by reducing the number of times data must be read from the AFS file servers. 32. Integrated Login (as of 1.3.80) supports the ability to obtain tokens for multiple cells. See the "TheseCells" value in registry.txt. 33. New command line tool: afsdacl : Set or reset the DACL to allow starting or stopping the afsd service by any ordinary user. Usage : afsdacl [-set | -reset] [-show] -set : Sets the DACL -reset : Reset the DACL -show : Show current DACL (SDSF) 34. As of 1.3.80, the default @sys name list has been changed to "x86_win32 i386_w2k i386_nt40" for 32-bit x86 systems. The default for itanium will be "ia64_win64" and "amd64_win64" for amd 64-bit processors. 35. As of 1.3.80, symlinks to \\AFS[\all]\... will now be treated the same as symlinks to /afs/... However, please use /afs/... as the Windows UNC form will not work on Unix. 36. As of 1.3.80, OpenAFS for Windows implements the Cache Manager Debugging RPC Interface. The CM debugger can be queried with cmdebug.exe. Usage: cmdebug -servers [-port ] [-long] [-addrs] [-cache] [-help] Where: -long print all info -addrs print only host interfaces -cache print only cache configuration 37. If you are a site which utilizes MIT/Heimdal Kerberos principals to logon to Windows via a cross-realm relationship with a multi-domain Windows forest, you must enable Windows logon caching unless the workstation is Longhorn Beta 1 or later. 38. VLDB and File Server Preferences can now be provided initial values using registry keys. This is useful for managed machines in a Windows domain which are centrally located (e.g., in a computing lab.) See registry.txt for details on the "Server Preferences" keys. 39. As of 1.3.81, timestamps on file stored in AFS are reported to Windows in UTC all year round. Previously, in locales with daylight savings time, the time reported by AFS to Windows when DST is active was UTC+1. This was done to preserve the relative local time for the user. A file stored at 11:00am EST in January would be reported as having been stored at 11:00am EDT in June. Unfortunately, this has the negative side effect of changing the reported timestamp from 16:00UTC to 15:00UTC. Since Windows treats all file times in UTC, data synchronization applications which rely on the timestamp would believe that all files stored in AFS had changed. This will no longer be the case. It should be noted that Unix based operating systems (such as Solaris) do not appear to report file times to applications in UTC. They do preserve the relative local time. This may confuse some users who are used to being able to compare the timestamp in an Unix shell with the timestamp from the Windows explorer. During DST, these two times will no longer agree even though they are in fact describing the same time. 40. If the installer refuses to install and complains about an RPC configuration error, check to ensure that the following registry entries are present and that they refer to the dll "rpcrt4.dll": HKLM "SOFTWARE\Microsoft\RPC\ClientProtocols" "ncacn_np" HKLM "SOFTWARE\Microsoft\RPC\ClientProtocols" "ncacn_ip_tcp" HKLM "SOFTWARE\Microsoft\RPC\ClientProtocols" "ncadg_ip_udp" 41. Starting in 1.3.83, when Integrated Logon is used in conjunction with KFW, the Kerberos 5 tickets obtained during the process of generating AFS tokens are preserved and stored into the default ccache within the user logon session. 42. 1.3.83 adds a new command, "fs minidump". This command can be used at any time to generate a mini dump file containing the current stack of the afsd_service.exe process. This output can be very helpful when debugging the AFS Client Service when it is unresponsive to SMB/CIFS requests. ------------------------------------------------------------------------ Reporting Bugs: Bug reports should be sent to openafs-bugs@openafs.org. Please include as much information as possible about the issue. If you are reporting a crash, please install the debugging symbols by re-running the installer. If a dump file is available for the problem, %WINDIR%\TEMP\afsd.dmp, include it along with the AFS Client Trace file %WINDIR%\TEMP\afsd.log. The AFS Client startup log is %WINDIR%\TEMP\afsd_init.log. Send the last continuous block of log information from this file. Configuring DrWatson to generate dump files for crashes: * Run drwtsn32.exe to configure or to identify where the log and the crash dump files are created: - click Start > Run... - type drwtsn32 . - Select either a Crash Dump Type: Mini or Full. - Clear Dump Symbol Table - Clear Append to Existing Log file. - Check Dump All Thread Contexts. - Check Create Crash Dump File * Next run the monitoring module of Dr. Watson: - click Start > Run... - type drwatson . - Once a crash happens, Dr. Watson generates a dump file and a report in the log file, including the address of the crash and the stack dump. Once you have the Dr. Watson's logfile and minidump, zip them and send them as attachments with your e-mail to openafs-bugs@openafs.org. When reporting a error, please be sure to include the version of OpenAFS. ------------------------------------------------------------------------ How to Contribute to the Development of OpenAFS for Windows: Contributions to the development of OpenAFS for Windows are needed.
