Anyone have any ideas? I feel almsot meked with no antivirus on my machine.

I don't know what versions of Vista SEP supports, but what version are you running?

I have about 30 machines here running Vista Business that I rolled SEP out on with no problems. Other than I usually have to push the client out 2 or 3 times before the install takes.

I am runing Vista home Ultimate, with SEP 11. Still no joy. I also had issues installing on my sons laptop, but messed around long wnough to get it setup and runnning. Attempted to set up my desktop in the same manner and I still get the same error, I really think the issue is somewhere in the Control panel>programs>turn windows features on or off>IIS section....man, this is some kind of frustrating!

Thanks for the look see, though
