Error deleting project in TFS -

I created a "test" project that I want to delete using the following command: TfsDeleteProject / server: xyz \ sqlserver2008 Receiving this error "Test": TF30076: You can not solve the name of the typed server or the Uniform Resource Identifier (URI), xyz \ sqlserver2008, Team Foundation Server if you type the name of a server Match it with the name that is typed in the Embedded Team Foundation Server dialog No need. If you type URI, then it should use the following syntax: http [s]: //: The server example is valid. (TFS is an app level and DB is on separate boxes) but what can be done?

xyz is the server name eht, sqlserver2008 db example, for example i access dbname using xyz \ sqlserver2008 using the SQL Server Management Studio Client app.
