Well it turns out that we had a virus get into the network yesterday. It kept me busy from 8am right until 3:15. The funny thing is that I was getting the car serviced so I didn't show up in the office until 9:30.
So it turns out that some of our beloved users was kind enough to introduce that. Since the virus went dormant it was hard to find and remove. But after much hard work by our department we found it.
That is the good side. The down side was that one of the team memebers in the morning went "Oh the computer was off so there is no virus." They never considered that the virus could morph or spoof it's address. Oh well lessons learned....I hope.
