Philip, I have seen this issue in our office also, but then I was running beta version of AC. I am hoping it wont happen after installing the full version.

We have 5 PC's and 3 dumb terminals connecting using TS. I also dont have a domain.

I can find almost no log entries in sql or server 2008 event log that gives me a clue why the connections drops
