I tried to put SP2 on a standard windows 2003 server. The machine didn't have much disk space left but It did its usual checks for disk space at the start, then started installing the service pack. So I thought it would be fine. Half way through the installation it failed with an error and started rolling back the installation. This was taking forever due to the lack of disk space.
Anyway half way through the rollback it failed with an error, so now the server is in a kinda half updated state of SP2. The uninstall folder was removed by the roll back. Now the server is incredably slow and I'm scared to reboot it incase it doesn't start up again.
The server is an application server running 1 app and isn't backed up at the moment.
Any ideas on my best course of action?
