"# re: Team Foundation Server without Active Directory - there a minimum version that is require to run this Team Foundation Server? And do we need to upgrade to an Architecture licence as we are currently using MSDN Licence?"

Feli,
It's not necessary to upgrade to a Visual Studio Team Edition for Architects version. So that you can see what all each edition includes or requires, here's a link to the Visual Studio Developer's Center (where you can see datasheets about each of the role based products), a link that discusses features/requirements for Team Foundation Server, and a copy of our licensing terms. I’ll be posting some related requirements from our pre-release planning guide over the next few days.

Thanks for the question,
