How to Determine If a Hotfix Is Compatible with Terminal Server (196334)

SUMMARY

When installing hotfixes on a server running Windows NT Server 4.0, Terminal Server Edition, it is important to confirm that the hotfix has been built to run on Terminal Server. Hotfixes that are built to run on Windows NT Server 4.0, Terminal Server Edition will have the 0x8000 bit set in the last two bytes of the FileVer property of the VS_FIXEDFILEINFO structure. You can use the Filever.exe utility to examine this structure.

When you use the FILEVER utility on Apimon.exe from the Support directory of the Windows NT Terminal Server Edition CDROM, you will see the following information:

Note that the FileVer property shows a version number of 00040000:05658004 (in hex) and 4.0:1381.32772 (in decimal). In this example, the last two bytes are 0x8004. Because the 0x8000 bit is set, this file was built for Terminal Server. Therefore, any number greater than 32767 in last position of the dotted decimal version number will be compatible.

The Filever.exe utility can be found in the Windows NT Server 4.0 Resource Kit Supplement Two (or later). For more information, see the resource kit documentation and the following article in the Microsoft Knowledge Base:
