Debugging issues

Greetings,

System specs are Windows XP, SP2, 2.6ghz, 763ram. I am trying to use the debugging tool found here under FAQ's. My first question applies to the initial path. Should the path begin with SRV* etc... or just the c:\symbols etc....? I follow the instructions down to the debugging screen and receive a message that the path is invalid.

I have tried it both ways(with and without the SRV*) and the result is the same; invalid path. Its does however point to "ntoskrnl.exe" as the problem.
I have gone no further than this step. Any enlightened guidance would be welcome and appreciated.
