Windows: if no known IP addrs, query the addr list
If cm_noIPAddrs == 0, then no servers will be probed. If
syscfg_GetIFInfo() fails then cm_noIPAddrs is set to 0. Therefore,
also set cm_LanAdapterChangeDetected to non-zero if syscfg_GetIFInfo()
fails so that the interface info can be queried again prior to a server
probe attempt.
