Attached to internal bug report is a project from customer. This project was added to customers TFS server. When I open it I get "Unable to connect to source control: The remote name could not be resolved...". This is expected since his TFS server is not on our network. I expected a follow up dialog asking me to unlink it from TFS, but this did not happen.

Now when I click "Connect" to add it to my TFS source control instead, I get prompted with the same error message which blocks me from adding it.

It seems the only way to move the project from one TFS source control to a completely different TFS source control is to delete or hack the settings.aiis file to cut out the source control settings. VERY inconvenient and error prone.
