SYMPTOMS
An SNA Server Windows 3.x application (for example, the 3270 applet) can't connect to SNA Server over TCP/IP sockets or IPX/SPX when started a second time.



CAUSE
This problem may occur on a Windows for Workgroups (WFW) 3.11 client if WFW password caching is disabled and an old cached password file containing the incorrect password still exists for the user.

The SNA Server Windows 3.x client (Wnap.exe) attempts to use a cached WFW password, if one exists on the computer, instead of sending a NULL password set by the user in the SNA client logon dialog.



RESOLUTION
A fix to SNA Server 3.0 is available for this problem.



STATUS
Microsoft has confirmed this to be a problem in SNA Server version 3.0. This problem was corrected in the latest Microsoft SNA Server 3.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
