Environment: fresh installation of Team Foundation Server 2010 Beta 2 on a WS2008 ENT SP2 + SQL Server 2008 SP1 Developer (10.0.2531) - RAM 4 GB.
I created a new test Team Project and a related Visual Studio 2010 Beta 2 solution (a copy of a VS2008 project converted).
Checked in the code files under the new Team Project source control and everything was OK. The operation has been performed on a test virtual machine with VS 2010 Beta 2 installed side by side with VS 2008 + VS 2005
After checking in I am unable to check-out project files nor to Get Latest Version (or Get Specific Version). I always get an error message for each processed file:
<FileName> + "TF30063: You are not authorized to access Microsoft-IIS/7.0."
Just to exclude communication\authentication errors between the server and the virtual client I tried the Get operations locally on the TFS server, but get the same TF30036 error.
Also tried all workarounds found on the internet but without success.
Except for the interaction with source coutrol everything seems to be ok (tfs web portal, project share point, reporting).
