Jon,
If you look at the original question, the author is asking do I need a dedicated computer to run AC on. My love for servers, notwithstanding, I don't think he needs a server. I do think he needs a dedicated computer for AC. I've probably given over 1,000 opinions on here (likely 50 of them heeded, lol), but the advice I stand by the most is don't let a user on the computer that is running the database.
