Last week a colleague tried to create a new team project on our freshly installed Team Foundation Server 2012 environment.
But when he choose the Add new Team Project option from Visual Studio 2010, he got the following error back:
TF30172: You do not have permission to create a new team project.
Don’t be fooled, this error has nothing to do with security. So don’t go check all your permissions, it will not help. Instead open up Team Explorer 2012(or Visual Studio 2012) and create the new project from there.
