Hi,
I am running WinXP with some hotfixes installed, one of the hotfixes has
upgraded ntoskrnl.exe, here is the following lm lv info for the new
ntoskrnl.exe :
kd> lm lv
start end module name
804d0000 80699e80 nt
\windbg_srv\symstore\os\ntoskrnl.pdb\A6C32BE0B0FD4CE7B42CF7C11D3214FC4\ntos
krnl.pdb
Loaded symbol image file:
\windbg_srv\symstore\os\ntoskrnl.pdb\A6C32BE0B0FD4CE7B42CF7C11D3214FC4\ntos
krnl.pdb
Image path: ntoskrnl.exe
Checksum: 001D22BF Timestamp: Mon Feb 25 23:32:36 2002 (3C7AC994)
MS has added the .pdb for this build of ntoskrnl to the symbol server but
the symbols do not conatin all the info the ntoskrnl.pdb from the release
does, the effect is that many WinDbg commands do not work, for example
‘!process 0 0’ does not work and outputs :
kd> !process 0 0
**** NT ACTIVE PROCESS DUMP ****

But as you can see 805400d8 is readable.
I deleted the copy of ntoskrnl.pdb it was using from my local store in the
hope MS had fixed the problem and I would get the new version when it
downloaded it again but still the same problem.
Help!!!
Yours
Roger
