When you setup TFS for the first time, usually you use the TFSSetup account. And with this account you are going to login for the first time.

However, once your environment is complete, you will want to login as a different user, but the credentials you used for the first time is already cached...

The first idea I have in mind was: remove the server from the registered server list and add it again, but... the button "remove" is disabled.

After digging (more than 30 minutes) I found the solution here: http://forums.microsoft.com/MSDN/ShowPost.aspx?Pos...

So here is the tip, go to control panel, UserAccounts->Advanced->Manage Passwords and remove the server from the list.
