When trying to install Exchange 2010 SP3 UR1, I was given an “Exchange Server 2010 Service Pack 3 Update Rollup 1 Ended Prematurely” error message. Turns out UAC is getting in the way of the installer. By running the installer from an elevated command line, you can install the update with no problems. Here’s a page that shows you what to do. It’s written for Service Pack 2, but it also applies here:
This one stressed me out for a bit today. After installing a heap of updates on an Exchange 2010 HUB/CAS server I told it to restart in order to apply them. Everything’s fine until I get to the “Preparing to configure Windows. Do not turn off your computer” message, and then things come to a grinding halt. Exchange services are still running and you can ping the server, but you can’t RDP into it or do much else except stare at that screen.
After some research it looked like the answer was to open up a new MMC window, add the Computer Management snap-in, and point it to the server in question. Take a look at the services running on the server, find the “Windows Modules Installer” service, and re-start it. In my case, that service was marked “Stopping”. In that state, you can’t do anything else to it; all the options are unavailable. So, after some more digging, I found a way around that here:
By using a third-party utility to kill that process on the server, it immediately continued it’s restart procedures, applied all the updates, and restarted successfully. Huzzah!
