I have experienced this problem a few times and there is now a hotfix for a problem with mapping and accessing DFS shares with Windows 7 clients. Hotfix can be requested from Microsoft Support. Basically you get “An unpexcted network error occured” or a couple of other issues and cannot access the DFS share. Patch and make the problem go away.
