SYMPTOMS
You receive the following error when running the update program for Microsoft Exchange Server 4.0 Service Pack 3 to update a server that is only running the Microsoft Exchange Server Administration program:

This version of Exchange Setup can only upgrade servers that are

4.0a/SP2. Upgrade the server to 4.0a/SP2 and then run Setup again.



CAUSE
The update program is looking for registry entries that do not get installed when only the Microsoft Exchange Server Administrator program is installed.



WORKAROUND
To work around this problem, you can make a change to the registry.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows NT. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

 Start Registry Editor (Regedt32.exe).  Under the HKEY_LOCAL_MACHINE subtree, go to the following subkey:      SOFTWARE/Microsoft/Exchange/Setup   Add the following value:      NewestBuild Add this value as a REG_DWORD, and enter the Data "3e2" in hexadecimal. The full entry in the registry will look like:      NewestBuild : REG_DWORD : 0x3e2  Quit Registry Editor.</ol>
