Removing SNA Server Removes Installed Transaction Programs

 Last reviewed: July 18, 1996
Article ID: Q148956
The information in this article applies to:
  • Microsoft SNA Server for Windows NT, versions 2.0 and 2.1, 2.11, or 2.11.sp1

SYMPTOMS

When you remove SNA Server 2.x prior to either upgrading or reinstalling SNA Server, the SNA setup program will delete all registry entries related to SNA Services that you have installed, such as APPC or CPIC transaction programs (TPs), for example, the APPC Ping (APINGD) program.

CAUSE

The problem is that Microsoft Windows NT services defined as SNA Server TPs have certain data in the registry that SNA Server recognizes as its own and removes them when SNA Server gets removed. Also Windows NT applications that are defined as SNA Server TPs are configured under the SnaBase registry key that is removed when SNA Server is removed.

RESOLUTION

Before you remove the SNA Server, you can use Regedt32.exe to backup the affected subtrees. Also, you can use TPSETUP to reinstall the TPs back into the registry.
