Symptoms

When you upgrade an SNA Server 4.0 system that uses the OLEDB Provider for DB2 or ODBC Driver for DB2, the SNA DB2 Service is not removed.

If you attempt to start the SNA DB2 Service after the upgrade to Host Integration Server 2000 is complete, you receive the following error message:
Could not start the SNA DB2 Service on Local Computer.
Error 2: The system cannot find the file specified.

Cause

The OLEDB Provider for DB2 and the ODBC Driver for DB2 that are included in Host Integration Server 2000 have been redesigned and no longer utilize the SNA DB2 Service. The HIS 2000 Setup program incorrectly leaves this service listed in the Services utility in Control Panel.

Workaround

In the Properties for the SNA DB2 Service, set the Startup option to disabled. This will keep the SNA DB2 Service from trying to start on your system.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.


To completely remove the SNA DB2 Service from the Services utility in Control Panel, remove the following key from the system registry, and then restart the system:

1.Start Registry Editor (Regedt32.exe).
2.Locate and select the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SnaDb2
3.From the Edit menu, click Delete.
4.Quit Registry Editor.
