Background - SBS 2003 retail version purchased/installed by Dell.
When SP2 first came out the installation of SP2 failed and may have been left in an incomplete state. I believe the system ran out of disk space during the installtion of the SP. I don't remeber the details but after some work, the server was functioning again but subsequent tries to install SP2 failed. As a result, I disabled Windows Update because it kept trying to install SP2.
Since I am now about 2 years behind in updates, I want to get this resolved. After some research, here's what I find:
The My Computer Properties General tab displays SP1.
The registery key: HKEY_LOCAL_MACHINE\SOFTWAR
ackNumber does not have an entry. Microsoft says that it should be 0x00000001 if SP1 is installed.
The Add/Remove programs displays an entry for Windows Server 2003 Service Pack 2.
I'm looking for advice on the best course of action to get SP2 installed/re-installed.
