Cannot seem to find a pdb file for win32k.sys

[Avi Cohen Stuart]

Hi,

I'm inspecting a crash at a customer site with W2K3/Citrix but windbg cannot
seem to find a symbol file for win32k.sys

Is this pdb file missing or is it a citrix special?

Hi ,

Can you check the below location for the win32k.pdb file

C:\Program Files\Debugging Tools for Windows
(x86)\sym\win32k.pdb\F915A35BC19D40E18F5D441F8BB7068B2

Hello Sainath.

Avi is looking for a different version of the file than you have. You can
tell because your hash directory name does not match his.

Avi, I am asking around for you. As I'm sure you've heard, we don't commit
to have symbols for everything and normally we can track down every missing
file. That said, I'm looking and hope to get back to you soon.

Pat,

Thanks. I know that not all symbols are committed for everything but usually
the MS symbol server does a very fine job.
Thanks for the effort.

Avi.

Hi Pat,

Thanks the for the info, i thought that every pdb file which we download
from the microsoft symbol server would be the same , so i thought of pointing
him to the location where i have my file

But that was good explanation, i have a question

i have tested this behavior on second system, i downloaded the symbol
package and extracted on to c:\winnt\symbols and i found the win32k.pdb under
c:\winnt\symbols\sys folder

And i have a question--

if i provides relevant path of my symbol files and perform .reload , windbg
look for the symbol file path and then the corresponding folders and loads
the pdb files.

So i see some pdb's are listed under "C:\Program Files\Debugging Tools for
Windows (x86)\sym " and some under "c:\winnt\symbols\sys " folder , how does
these matter ?

i think the downstream ( sym ) folder would be referrenced first by the
windbg and then the symbol path ?

Hello Avi.

I asked around and unfortunately I was unable to get symbols for the image
you requested.

sorry,

Hello Sainath.

I am afraid I do not understand what you mean with this question.

"how does these matter ?"

As far as looking in the downstream store first, that applies to a symbol
server path. It does not apply to anything outside a symbol server path.
So your statement is not always true when you intermingle symbol server
paths with traditional symbol paths.

Example symbol path

srv*c:\cache*http://msdl.microsoft.com/download/symbols;c:\windows\symbols

In this case, the debugger will look in the following order...

c:\cache
http://msdl.microsoft.com/download/symbols - if there, it will copy to
c:\cache
c:\windows\symbols

Example symbol path

c:\windows\symbols;srv*c:\cache*http://msdl.microsoft.com/download/symbols

In this case, the debugger will look in the following order...

c:\windows\symbols
c:\cache
http://msdl.microsoft.com/download/symbols - there, it will copy to
c:\cache

Hi Pat,

Thanks for looking. This will make the analysis (a lot) harder.

Avi.
