We had this issue and setting the "Load User Profile" in IIS application pool settings to True worked for us. But then the same issue came back and we found setting "Load User Profile" in IIS application pool settings to False fixed the issue once again. So it appears to me that it is the toggling of this setting that is fixing something rather than the actual value it is set to. No matter what "Load User Profile" in IIS application pool is set to, I would try toggling it to the opposite value, refresh the application pool and see if that helps. If anyone tracks down the root cause of this please share.

I ran into this same issue, but setting Load User Profile to TRUE didn't work for me. What did eventually work was going into the registry and adding a "HKCU\Software\Microsoft\VSCommon\12.0\ClientServices" key for the appropriate user(s). Apparently the TFS assemblies get a little cranky when you try to use them on systems without Visual Studio installed on them.

I have been having the same problem and have solved it by setting the "Load User Profile" in IIS application pool settings to True.

I don't know if this is some new dependency in TFS 2013 or whether IIS 8.5 has changed the default, but this fixes it for me.
