Andre,
Thanks for the assistance, by the way. I know I (we) beat you guys up
sometimes, but realize it may be after long hours of trying to fix a problem
when its the tools I’m using that is hiccuping.
Here is the information you requested. I also included the !irpfind print
outs. I note that you asked for nt!_POOL_HEADER and that irpfind indicates
nt!POOL_HEADER. Typo?
0: kd> dt nt!POOL_HEADER
Symbol nt!POOL_HEADER not found.

When debugging XP, what do you get from the following command:
dt nt!_POOL_HEADER
If that does not work, there is a problem with your symbols.
If that works and the extension still fails, it’s a bug in the extension.
For Windows XP, every single extension had to be rewritten so it would work
for 64 bit. Secondly, we had to deal with the fact that at MS we use full
symbols, but only give out public symbols to customers. So that has caused
some problems with certain extensions.
If it is a problem with the extension, we can send you a private with the
fix.
