Hi, thanks for the replies.
graywolf, that's a fair question and I should have mentioned in my first post that the workgroup is indeed the same on all devices attached.
Spectrum, thanks for the tips. I followed through on the instructions you posted but alas I still cannot browse to \\tower\ using Explorer on the XP box. ping tower works fine, as you'll see in the notes I posted below from the cmd prompt. It's just browsing the filesystem is the problem, and only from this XP PC. I've attached the hosts.txt file as requested.
Any other tips to try would be most welcome.
