TFS Error: “Source Control - Unable to Access Database”

Question

I am currently using TFS with Visual Studio 2010 Ultimate and getting this error when I try to open up my solution:

The associated source control plug-in is no

Answer 1

Is this a new Solution? This error is often caused when a solution has been bound to another source control system (VSS for example). It could be that the other machine you tried had VSS installed and your machine doesn't.

Try unbinding the solution, then go to tools, Options, source control and make sure TFS is selected. finally rebind the solution.
