Tried installing Windows Server 2003 SP1, but it freezes during install. Windows Server 2003 SP1 is listed in the installed programs list, but it isn't reflected in System properties. So I'm guessing it is a partial, failed install. Tried to remove it using add/remove programs - Errored out with "The system can not find the specified file". Tried to install SP2 to overcome this issue. When trying to install Windows Server 2003 SP2 I receive an Error "Setup could not verify the integrity of the update.inf. Make sure the cryptographic service is running". I verified that it was running. Searched the Internet for the SP2 installation error. Saw lots of suggestions to renam the %Systemroot%\System32\Catroot2 folder to Catroot2.old and reboot. Did so; it was recreated by Windows but it didn't fix the issue. I tried creating a log during installation of SP2 using: update /verbose /er /log:{specified path} /norestart A log was not created at my specified path, but the Cabuild.log from the Verbose switch was created in the Windows directory and the contents are below. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Cab Build Debug Log Begins ************************* LoadOrInstallBranchesInf: Source branches.inf is newer; using source.
