I kept getting the same error message everytime. I tried changing all sorts of settings on my router and my computer's networkin panel. Me and my friend then came up with the brilliant idea of using FTP to transfer files, since that's all I wanted to do. I setup FTP, which doesn't take a lot of skills. You just need to get a program called ServU, atleast that's what I use, to start a server...and then either ServU or another program called SmartFTP, or Cute FTP

All of them are compatible with each other, since I use SmartFTP on my Pavillion computer and CuteFTP on the other computer, and it takes only some modest brains

But FTP didn't seem to work either, which i figured out was because my node type on the other computer was unknown. So I followed Ross's advice of changing my Node type to Hybrid on both computers. This solved the problem, I can see both computers on the Workgroup, and now my FTP works fine. I haven't tried the Network Set Up Wizard in WINXP. Before I couldn't see my other computer on the work group, I kept getting the perimission error. Now I can see both my computers on the workgroup.

So just try changing both node types to Hybrid, and use FTP if u just want to share files.
