If your running Vista, you need to change your DEP settings. Let me know if this is the case and I can get my husband to run through it with you when he gets home in 1.5 hours.
It's fairly simple but my brain isn't working right tonight (I can't work my head around your time being 2 hours later than mine even though I'm in MST! It doesn't make sense.) I could try if you need help before then.
