Create a simple MFC application in Visual Studio 2003 / 2005/ 2008. Start debugging by pressing F5.
Visual Studio debugger takes a long time to start debugging the application. This gives an impression that Visual Studio has hung.
Invalid symbol path location, or a geographically distant location where symbols are stored, causing high network latency.
Check if the _NT_SYMBOL_PATH environment variable contains valid information.
In the Visual Studio IDE, goto Tools->Options->Debugging->Symbols->Symbol File (.pdb) locations. Check if you have valid path here.
If you do have a valid path in either of these locations, try removing these entries to see if that helps. If the problem goes away, then you may have a high network latency causing delayed load of symbols and slow debugger startup/response times.
When the debugger starts up, it tries to load the PDB symbol files for loaded modules. High network latency can cause Visual Studio to become unresponsive. A local symbol cache can be used to work around the problem.
