Hi,
In a team foundation server, we created a team project. Added three groups in the project say G1, G2, G3. Added myself in all three groups and made sure that I am not part of any other groups especially "Project Administrators" and "Team Foundation Administrators". For G1 we keep both "Allow" and "Deny" for "Delete Team Project" unchecked. For G2 we keep "Allow" checked and for G3 we keep "Deny" checked. Then as per article http://msdn2.microsoft.com/en-us/library/ms252587(VS.80).aspx I shouldn't be abled to delete the team project. But I could delete team project using utility TFSDeleteProject.exe utility.
Am I missing something
Regards,
Saurabh

Team Foundation Server permissions not working as documented

Saurabh,
Thanks for the posting.
Yes I agree that this should disallow you from deleting a project. I'll double check with some of our team to investigate this a little further.
Thanks,

There are two direct tests for admin privileges. The first tests to see if you (or another user) are a member of the server-level administrative group:
Note that there is a colon after the letters adm. The username is optional. If omitted, this command will check if the logged-in user is a member of the administrators group.
The second form of the command requires that you have the Team Project URI. The easiest way to get this string is to open a Team Explorer client, select the project in the Team Explorer tool window and look at the Url property for the project. It will be of the form: vstfs:///Classification/TeamProject/<GUID>. Take that string and substitute it into the security membership command given above.

This does not reproduce for me, but the perhaps you are a TF or Project admin without knowing it You must have had admin priviledges at some point in order to create the groups and set the permissions. Unfortunately, it is not possible to overwrite the implicit allow of being a member of an admin group.
Please verify your group memberships using the TfsSecurity tool (located on the AT).
TfsSecurity.exe /server:<server name> /imx <domain/user>
