Thread: Unable to install Windows Update in Windows Server 2003?

I am running Windows Server 2003. I have WSUS on the Server. Whenever I start the workstation, it shows me message that need to install the Security Update for Microsoft XML Core Service 4.0 Service Pack 2 (KB954430). When I click on install, the reboots and again the message appears. What to do now?

Check in the installed updates window whether it is installed or not. If installed, then uninstall it first and then again reinstall it. This time, try to install manually. Below is the download link for KB954430 update:
