Try installing the TFS 2010 Power Tools from here: TFS 2010 power tools, then click Start, point to All Programs, point to Microsoft Team Foundation Server 2010 Power Tools, point to Microsoft Visual Studio Best Practices Analyzer, and then click TfsBpa.exe. It does a great job of diagnosing these kind of issues.
