Thank you, richthomas!
I was having at least one of the OP's problems, that being no internet connection. Also, I couldn't get the screen resolution to go above 1920 x 1440 and there was no sound from my speakers. I even erased and reinstalled xp 32-bit on my Boot Camp drive. Then I came across this thread, dug out the restore DVDs, popped in the first disc and bam! everything works just like it does with my virtual machines.
Interestingly, I didn't have to do this on my iMac (purchased in December 2007), so it didn't occur to me that I'd have to do it here. Now I have my screen resolution at 2560 x 1600 (30" ACD) and Windows runs like it should.
Thanks again.
James
