SYMPTOMS
If you have a network session established with an IBM LAN Server and attempt to log on to a Windows NT Server domain, the following error message may appear on your Windows for Workgroups client computer:

No domain server was available to validate your password. You were logged on without password validation.

Network Monitor displays the following message during a network capture:

ICMP: Packet Type = Destination Unreachable.

CAUSE
The message captured by Network Monitor appears if an OS/2 server or client sends unrecognized responses to the browser broadcasts originally sent by the Windows for Workgroups client computer. Consequently, a network storm occurs which does not allow the Windows for Workgroup client computer to log on to the Windows NT Server domain.

RESOLUTION
A fix to this problem is available from IBM Technical Support at (800) 772-2227. The IBM products discussed here is manufactured by IBM Corporation, a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
