Debugging Tools error about wrong symbols

Anyone here with experience with the Windows Debugging Tools Windbg?

I found that by coincidence one day while trying to figure out a BSOD, and it has worked so wonderfully for me for a few clients.

But today I sent a minidump over the internet onto my PC to analyze, and I am getting an error message:

***** Kernel symbols are WRONG. Please fix symbols to do analysis.
Unable to load image watchdog.sys, Win32 error 2
*** WARNING: Unable to verify timestamp for watchdog.sys
*** ERROR: Module load completed but symbols could not be loaded for watchdog.sys

***                                                                   ***

The only thing I can think of is that the computer I got this minidump from is running XP Home, and I am running XP Pro.

Any idea how I can get the debugger to work anyway? Where can I get these symbols it talks about?
Or am I doing something wrong?

Thanks!

well if its connected to the internet you could use this command so it will take them right off the microsoft site.
kd -y srv*c:\symbols*http://msdl.microsoft.com/download/symbols -i c:\windows\i386 -z c:\windows\minidump\minidump.dmp

if you want the GUI version use this command:
windbg -y srv*c:\symbols*http://msdl.microsoft.com/download/symbols -i c:\windows\i386 -z c:\windows\minidump\minidump.dmp

this is assuming your i386 is still in c:\windows and all that

Cool!
Do I have to add the -z part or can I keep opening dump files using the GUI?
I'll try it without -z because I am too impatient with new toys to wait for an answer ;-)

Thanks very much!

Are there any tutorials for the debugger? I am quite certain I am not even using a tenth of its potential in finding the source for Windows problems...

Dang, whoever installed my laptop before I got it didn't leave the i386 folder on - there is one that's about 520MB in c:\windows\ServicePackFiles\i386, and a few smaller ones.
Will it work without, and how can I get the folder in there - just copy it from the Windows CD?
Thanks again!

And another problem (which I should have seen coming): I can't create a shortcut with asterisks... Maybe a batch file will work instead...

OK, it did work better than before, so thanks again for the information so far!

What are these symbols it is talking about anyway?

(I'll stop now and leave the debugger alone until tomorrow *g*)

Its the symbols the debugger needs to understand what the minidump is saying thats all it is just like a decifer key.
