I've got a similar problem to "BSOD - Unable to verify timestamp for ntoskrnl.exe", in that I can't seem to get the correct symbols to read ntoskrnl.

I've followed the advice given by BK1E, but still can't get a result.

Text from debug below:

***** Kernel symbols are WRONG. Please fix symbols to do analysis.

How do I fix this issue?

OS is Windows Vista x64 SP2.
