tfs loses workspace mapping. No workspace matching * found on this computer

Question

Since this morning I have been having trouble with my TFS. It actually forgets the workspace mapping and doesn't recognize that the solution has been added to source control. There is an option to actually add the selected projects to source control.

I don't want to edit workspace and make it download all files again. I tried using the tfs command prompt

C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC>tf workspaces /computer:LAP14643 /owner:* /server:cs\Development
No workspace matching *;* on computer LAP14643 found in Team Foundation Server cardontfs\Development.

tf workspaces
No workspace matching * found on this computer

Thank you

You should run tf.exe from a mapped folder.

I would have thought that "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC" is not mapped folder.
