"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That's what we use here ( AD 2003) and never had any problem with it. Not sure in a mixed unix-windows environnement but i'm pretty sure it would not cause a problem.

good luck
