I had an error in Team Foundation server saying something like one of my folders were already mapped to this local path from another server. So I looked around and couldn't find a fix for it on the internet. I had to figure this one out my self so I thought I would share my findings.
In order to remove this mapping from TFS because maybe you deleted the folder on your desktop a long time ago. You need to go to File -> Source Control -> Manage Workplaces.
From there you have the option to remove any mappings you wish in TFS. Just thought I would throw that out there. Took a while for me to find it and thought I should share it.
