Running SNA Server 2.11 on the Windows NT 4.0

MORE INFORMATION

1. The SNA Server Administrator program will encounter an application exception when using the Select Domain dialog to change focus to another domain when running on the Windows NT 4.0.
   
   Another possible symptom of this problem is a series of LAN Manager error messages that appear after selecting the Select Domain option in the SNA Server Administrator program.
   
   To work around this problem, rename the following SNA Administrator file:
   
   rename <snaroot>\system\snasfd.dll snasft.211
2. SNA Server 2.11 overwrites an older version of license manager (Liccpa.cpl) on Windows NT 4.0, causing new Windows NT 4.0 license system features (such as replication and support for secure certificates) to be disabled.
   
   To resolve this problem, reapply the Windows NT 4.0 version of Liccpa.cpl to the <winntroot>\System32 directory.
3. Eicon WAN Services from SNA Server 2.11 SP1 only works on Windows NT 3.51. SNA Server 2.11 Service Pack 1 includes Eicon WAN Services v3r3, though this version only works on Windows NT 3.51.
   
   Contact Eicon for an update to Eicon WAN Services to use on Windows NT 4.0.
4. On the Help menu, when you click About SNA Server, the following incorrect information is diplayed:

   Microsoft SNA Server for Windows NT
   December Server Beta
   
   Administration Program
   Version 2.0.0.0
   
   Copyright 1992 Microsoft Corp

   This does NOT indicate that an old version of SNA Server is being used and should be ignored. To determine the actual revision level of SNA Server, run the "SNAVER" command, click Browse and select the <snaroot>\system\SNAADMIN.EXE program. If SNA Server 2.11 SP1 is being used, the lower portion of the message box will show:

   SNAADMIN.EXE Version 2.11.0.309.

5. Server-to-server communication over IP routers fails if WINS is used.
   
   See the following knowledge base article for more information on this problem.

   155883 NT 4.0 Breaks SNA Server 2.x Server Communication over IP

   This article documents the availability of a Windows NT hotfix for this problem, available through Microsoft product support.
6. When you invoke SNARAS connection, Windows NT STOP screen 0x0000001E appears.
   
   When using the SNA Server 2.11 SP1 SNARAS feature on top of Windows NT 4.0, the following STOP screen will occur:
   STOP 0x1E (unhandled kernel exception)
   Parameters: c0000005 80111391 00000000 8014bec0
   This problem is fixed in Windows NT 4.0 Service Pack 2. This problem does not occur when running SNA Server 2.11 SP1 SNARAS on Windows NT 3.51.

Microsoft SNA Server 2.11 is supported on Microsoft Windows NT 4.0. This article will be updated as problems are found and as updates or workarounds are determined. It is recommended that the latest SNA Server 2.11 service pack be applied if running on Windows NT 4.0. Microsoft SNA Server 2.0 and 2.1 are not supported on Windows NT 4.0.
