When I set a breakpoint on one of the methods that appears on top of the stack (!CLRStack), I get lots of these messages for every DLL that the debuggee is referencing including the .NET Framework ones. ERROR: Module load completed but symbols could not be loaded Further digging into this shows that windbg is not loading every .pdb file that I make available in the symbols path. I've double-checked my symbol's path and it looks OK, but the following commands clearly show that not all PDBs are loaded correctly! 0:000 !sym noisy noisy mode - symbol prompts on 0:000 .reload Reloading current modules ................................................................ DBGHELP: ntdll - public symbols c:\symbols\ntdll.pdb\6992F4DAF4B144068D78669D6CB5D2072\ntdll.pdb .. 0:000 .sympath Symbol search path is: SRV*c:\symbols*C:\xc Expanded Symbol search path is: srv*c:\symbols*c:\xc I've c:\symbols being used for the cache and c:\xc being used for the .NET app PDBs that WinDBG seems unable to find. Any idea how I can use to help further troubleshoot this? Thanks
