SNA Client Fails on SNA Server 3.0 on French WinNT 3.51

• Microsoft SNA Server version 3.0.

SYMPTOMS

The version of the Security.dll file in Microsoft Windows NT 3.51 French version, does not support data encryption. The Microsoft SNA version 3.0 client will fail to work when trying to connect to an SNA 3.0 Server running on the French version of Microsoft Windows NT Server 3.51. The client connection will be rejected and an event 722 will be generated in the application event log.

CAUSE

The problem occurs when encryption is enabled on the SNA Server (even though the emulator being used does not support it or does not have it checked). It will only occur if Named Pipes/Microsoft Networking is selected as the client-server protocol.

NOTE: To enable Data Encryption, the administrator should go to the Properties page for the appropriate user/group, and then click "Use Client/Server Encryption" on the User Properties tab.

RESOLUTION

As a workaround, disable data encryption support because the underlying Security.dll does not have this functionality.

The following files have been updated to correct this problem:

   <snaroot>\system\snaserver.exe
   <snaroot>\system\snadmod.dll
   <snaroot>\system\snaevent.dll
   <snaroot>\system\snanw.dll
   <snaroot>\system\snaat.dll
   <snaroot>\system\snabv.dll
   <snaroot>\system\snanb.dll
   <snaroot>\system\snaip.dll
   <snaroot>\system\snalm.dll
   <snaroot>\system\adloc.dll
   <snaroot>\system\snabase.exe
   <snaroot>\system\snacfg.dll
   <snaroot>\system\sfcapi.dll

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):
