Debugging is a strange thing. Mostly, the root cause is never clearly and obviously displayed, as has been the case here though.
Normally, you would have to install from a huge .iso if you want Windbg Debugging Tools. This guy made it nice and easy, and small. All that is needed is simple extraction to the folder you want to keep it at permanently.
just do IT: standalone windbg v6.12.0002.633
Download 86 for 32 bit machines (host machine the software will run on) or 64 for 64 bit machines.
Then, all that is needed to set it up well is to use elevated command prompt (you know, with Admin rights) to cd to the correct directory you placed it at. Then run this command:
Windbg.exe -IA
Then, all you need to do is set a well symbol path in the debugger, while no crash dump is opened. To do so, Ctrl+S in Windbg. Enter this, then click OK: SRV*C:\SymCache*
http://msdl.microsoft.com/download/symbols
(Feel free to change the C:\SymCache local directory to any valid local folder on the machine.)
Done deal and ready to debug. Well, at least see the crash dumps correctly, that is.
