after I removed an active directory domain service, I lost all my accounts...then not only the SQL server and the TFS stopped working, the TFs administration console also says that I don't have sufficient right to add members... Now I manage to get the SQL server kind of running, and I can see my project in team explorer, but the TFS still says SQL access denied, SQL server says I don't have permission to add new logins or add my admin account to sysadmin, the TFS still give me the TF246017 tfs could not connect to the database and I don't have sufficient right to add member to any of the project groups... Anybody knows how can I get all these permissions back....?
