... I know who you are, but you are too much of a coward to reveal your real name on this board.

Listen, you dumb shit, we were on Win-XP. We bought a new fleet of servers pre-loaded with Win-7. Microsoft did not publish a list of applications that would be incompatible with Win-7. We wouldn't care about a list like that anyway ... we are concerned only with our application. We quickly discovered that we would need VM to run XP under Win-7, which is a crappy solution, so we run XP-SP3 on our production servers and Win-7 on our communications servers. Now, fuck off, coward.
