SNA Server Version Information and Windows NT Dependencies

• Microsoft SNA Server, versions 2.0, 2.1, 2.11, 3.0

SUMMARY

This article describes how to identify the version of SNA Server or SNA Server client software that is being used. Windows NT version dependencies are also described below.

All releases of SNA Server include the <snaroot>\system\Snaver.exe utility which displays an internal version number within every 32-bit SNA Server DLL or EXE module. Besides Snaver, or the module file dates, the following information can also be used to determine the SNA Server version:

• From SNA Server Admin (or SNA Server Manager), click About on the Help menu.

  WARNING: When running SNA Server 2.11 Admin on Windows NT 4.0, this displays "Beta Version 2.0.0" in error.

• Examine the following registry key on the SNA Server:

        HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/SNA Server/
        CurrentVersion/SnaVersion: REG_SZ: <version>
  

  The <version> will indicate the major version and service pack level. For example:

         2.11 Service Pack 2
         3.0 Service Pack 1
  

   Microsoft SNA Server
   Retail Version: 3.0 Service Pack 2

MORE INFORMATION

The Snaver.exe program can be used to display the internal build number of any SNA Server Win32 DLL or EXE module. When starting Snaver, it also displays a version number itself, which are listed below.

NOTE: The modules updated in each service pack will not display a uniform internal build number. Service pack modules are built incrementally. To determine the SNA Server version based on the internal build number, only the Snaver.exe *or* Snadmod.dll build numbers should be viewed, as described below.

The following table can be used to identify the version of SNA Server being used. The following versions of SNA Server have been released as of this writing:

   SNA SERVER     SNAVER.EXE
   VERSION        BUILD NUMBER   DATE OF BINARIES		
   ----------     ------------   ----------------------------------
   SNA 2.0        2.0.0.127      10/24/93
   SNA 2.10       2.1.0.267      9/3/94
   SNA 2.11       2.11.0.294     6/95 (NOTE 1)
   SNA 2.11 SP1   2.11.0.309     1/5/96 (NOTE 1, NOTE 2, NOTE 5)
   SNA 2.11 SP2   2.11.0.315     2/21/97 (NOTE 1, NOTE 4)
   SNA 3.0        3.0.0.414      11/17/96 
   SNA 3.0 SP1    3.0.0.433      4/9/97 (NOTE 3)
   SNA 3.0 SP2    3.0.0.462      9/30/97
   

        Admin Help/About dialog incorrectly shows the SNA Server version 
        as "Beta Version 2.0.0". To determine the actual SNA Server 
        version, Snaver.exe should be run instead.
   

        Customers purchasing SNA Server 2.11 after January 1996 should 
        have received the 2.11 SP1 version.

        purchasing SNA Server 3.0 after April 1997 should have received 
        the 3.0 SP1 version.

        internal build number will be unchanged. To determine if 2.11 SP2
        has been applied to the server, use Snaver to view the build number
        of the <snaroot>\system\Snadmod.dllL file, which will be 2.11.0.315.

        was made available electronically by Microsoft on ftp.microsoft.com 
        during December 1995. This version had several problems which caused 
        tcp/ip session drops, which were fixed in the SNA Windows 95 client 
        included in 2.11 SP1. The initial release of SNA Server 2.11 did not 
        include an SNA Windows 95 client since the 2.11 release predated the 
        Windows 95 general release in August 1995.
