My System Administrator renamed my computer. So where it was "MyLaptop2" it is now just "MyLaptop".
So now all my source control bindings and checked out files are looking for a workspace with "MyLaptop2".
Is there a way to redirect that workspace to my renamed (but still the same) computer?
This command run in the Developer Command Prompt for Visual Studio did the trick:
tf workspaces /updateComputerName:MyOldComputerName /s:"http://MyServer:8080/tfs/MyCollection"
It had to be run from the computer I wanted to assign the workspace to (that is how it gets the new computer name.
