I’m not sure about windbg, so my answer is from the perspective of ntsd.
Look into the option of setting up a script file with the symbol path
defined and symbol loading for the modules you want. If windbg supports
it, specify the script file on the command line when starting windbg.
That was just a thought. I don’t have windbg present on this machine to
try this out, sorry.

Thanks Johann
But can I some how tell the debugger not to load these symbols, as I do
not need them and save some time???

The time is taken because the system is looking for all the nonexisting
pbd files on the symbols server and the other locations. You can debug
your own source/driver without problems without these symbols …

I doubt you will get symbols for all the drivers listed below from the
vendors (Microsoft symbols come from their public symbol server), but
usually this is not neccessary. You need need to make sure you have
symbols for the driver you want to debug/troubleshoot.
What are you trying to debug/achive ?

Thanks Johann
Well the path change you described has helped me get rid of one of the
errors.
>>The other errors are simply that the symbols cannot be found
So what to do to fix this asyou pointed out wrong symbols or cannot be
found??
Symbol search path is:
C:\WINNT\Symbols;SRVc:\symbolshttp://msdl.microsoft.com/download/symbo
ls;C:\KernelCode\KernelWorkSpace\filter\objchk_w2k_x86\i386
Source search path is: C:\KernelCode\KernelWorkSpace\filter
Image search path is:
C:\KernelCode\KernelWorkSpace\filter\objchk_w2k_x86\i386
The errors I get is as follows. Any more Ideas??

C:\KernelCode\KernelWorkSpace\filter\objchk_w2k_x86\i386\filespy.pdb is
wrong, just specify the directory like
C:\KernelCode\KernelWorkSpace\filter\objchk_w2k_x86\i386
The other errors are simply that the symbols cannot be found and for the
last ones the timstamp of the symbol files is different to the timestamp
of the module which usually hints for wrong symbols.

Subject: RE: [windbg] Loading User Symbols
Hey Ladislav ,
A bit late reply . But I am still not able to remove the errors which
come in loading usermode symbols.
As you had said
_NT_SYMBOL_PATH is set as an user variable as follows :
SRVc:\symbolshttp://msdl.microsoft.com/download/symbols
Where “c:\symbols” is my symbol path.
My symbol file path as set in Windbg as
C:\WINNT\Symbols;SRVc:\symbolshttp://msdl.microsoft.com/download/symbo
ls;C:\KernelCode\KernelWorkSpace\filter\objchk_w2k_x86\i386\filespy.pdb
But I still get the following errors while loading the user symbols. It
takes too much time to load is my only problem… Any Ideas ??
Below is my error on load and on bug check
Thanks
anurag

1) Check where the senior stored the symbol files.
2) Then set the _NT_SYMBOL_PATH environment variable
3) Start Windbg.
Or alternatively, you may use the symbol server
