Im having problems uninstalling SP2 from my SBS 2003 server. When I try to uninstall I get the error message saying that simply the uninstall failed. I had a word with MS and they advised me to re-install SP2 as the error usually means that a SP2 file is either missing or corrupt and that it cannot be removed unless the files are replaced/repaired. When I try reinstalling (using the WindowsServer2003-KB914961-SP2-x86-ENU.exe executable downloaded directly from MS) I get the following error:
Setup could not verify the integrity of the file update.inf. Make sure the Cryptographic service is running on this computer.
Ive downloaded the service pack a number of times just in case there was corruption in the download which is causing the integrity failure, also Ive checked the services running on the server and the Cryptographic Service is running.
Any ideas about what do I need to do to ensure I can install/uninstall SP2?
