I renamed my computer name, and now my TFS workspace is broken in Visual Studio 2012.
When I type:
tf workspaces /computer:ABOTONJIC-PC /owner:* /format:
Open Command prompt and type as shown in below
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE
and type the following code with your credential
tf workspaces /updateComputerName:OldComputerName /s:"https://tfsServerName"
In CMD prompt
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE>tf workspaces /updateComputerName:OldComputerName/s:"https://tfsServerName"
