SNA Server Version Information and Windows NT Dependencies

ID: Q173284

The information in this article applies to:

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:

NOTE: Starting with SNA Server 3.0 Service Pack 2 (SP2), the Snaver.exe program will display the SnaVersion registry key also, to indicate the service pack level that has been applied. For example:
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
   SNA 3.0 SP3    3.0.0.471      4/8/98 (NOTE 6)
   SNA 3.0 SP4    3.0.0.476      5/14/99
   SNA 4.0        4.0.0.500      11/20/97
   SNA 4.0 SP1    4.0.0.500      5/22/98
   SNA 4.0 SP2    4.0.0.568      1/9/99
NOTE 1: If SNA Server 2.11 is running on Windows NT 4.0, the SNA Server 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.

NOTE 2: SNA Server 2.11 was refreshed when 2.11 SP1 was released. Customers purchasing SNA Server 2.11 after January 1996 should have received the 2.11 SP1 version.

NOTE 3: SNA Server 3.0 was refreshed when 3.0 SP1 was released. Customers purchasing SNA Server 3.0 after April 1997 should have received the 3.0 SP1 version.

NOTE 4: SNA Server 2.11 SP2 did not update the Snaver.exe program, so the 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.

NOTE 5: The initial version of the SNA Server Windows 95 client software 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.

NOTE 6: SNA Server 3.0 SP3 included refreshed client code and setup programs for Windows NT and Windows 95. However, these refreshes incorrectly set the SNA client version information in the registry to "3.0 Service Pack 2". The build will still correctly indicate "Build 471" to reflect that SNA 3.0 SP3 is applied on the client computer.

SNA Server and Windows NT version dependencies

SNA Server 2.0 - Server runs on Windows NT 3.1. SNA Server 2.0 hotfixes were required to run on Windows NT 3.5. This version is longer supported by Microsoft.

SNA Server 2.1 - Runs on either Windows NT 3.1 and 3.5. This version is no longer supported by Microsoft

SNA Server 2.11 - Server requires Windows NT 3.5 or greater (does not run on 3.1)

SNA Server 3.0 - Server requires Windows NT 3.51 or greater (does not run on 3.5)

SNA Server 4.0 - Server and Windows NT client requires Windows NT 4.0 Service Pack 3 or greater (setup prevents installation on NT 3.51 and earlier versions). When choosing to install COM Transaction Integrator (COMTI), OLE/DB Provider, or ODBC Driver for DB2, the system must be installed with Microsoft Internet Explorer 3.02 or later, and the Windows NT 4.0 Option Pack (COMTI requires Microsoft Transaction Server and optionally, IIS from the Option Pack). If COMTI, OLE/DB or ODBC are chosen, SNA Server automatically installs the Microsoft Data Access Components version (MSDAC) 1.5. See the SNA Server 4.0 release notes or Getting Started guide for specific software requirements and instructions.
