    I've got a web server that has a process that is hanging and I need some help reading the analisys report.  I'm not finding much data here.  Can anybody tell what else I can do to get these to have more information or help me understand whats here.


     Analysis Summary 
      Type Description Recommendation
      Information Symbols were not available to resolve the symbol "comsvcs!g_STAThreadPool+4". The COM+ STA ThreadPool report may not be accurate. Ensure that a symbol path is configured, enabling the proper symbols to be loaded.

    To modify or view the current symbol path from within DebugDiag, select Symbol File Path from the File menu. If symbols aren't available and/or a proper symbol path is already setup, then these threads should be manually reviewed further to determine what they are doing. For more information regarding debug symbols for Microsoft components, please visit the following site:
