Cannot load my driver symbol file

WINDBG
1

Hi,

I cannot load my symbol file for my driver “WDMDriver.sys” and I put
“WDMDriver.pdb” in G:\WINDDK\SYMBOLS\WIN2KSP3
Is there anything special to do to get it work ? Is the .dbg mandatory (I
read it was’nt for WIN2K) ? If it is, how can I generate a .dbg file ?
Here is an excerpt from the debugger to help to understand the problem

kd> .sympath
Symbol search path is:
g:\winddk\symbols\win2ksp3;srv*http://msdl.microsoft.com/download/symbolssrv

kd> .reload WDMDriver

Module “WDMDriver” was not found in the module list.
Debugger will attempt to load module “WDMDriver” by guessing the base

Please provide the full image name, including the extension (i.e.
kernel32.dll) for more reliable results.

“Module “WDMDriver” was not found in the module list.”

Use !drivers (or lmi) to verify that your driver is actually loaded on
the system, and then provide the full name of the driver when you do a
‘.reload’.

For example:
‘.reload WDMDriver.sys’
