Anyone else with problems with Service pack 1?

[Guest salan]

Hi All,

I have a WSUS server set up as a VM (VMWare) using W2K8R2. It works fine (nromally).

It needs service pack 1 on it. Every time I try to install it, I get the same problem. The things goes through until it says you need to reboot. When it reboots. It gets to 15% complete and hangs. I have left it for a day and still no joy. If I reset it, the VM is stuffed (wont get past wanting a recovery window but wont accept going to one). Fortunately I have a backup and a snapshot. But I just can't get past this 15%. I have tried turning the AV off(Eset), praying to everyone (not tried the virgins yet as hard to find!). any ideas?
