Re: LANs with XP
Hmmm. So you have a connection, that's good. But PC2 can't see PC1 a majority of the time? Well, from my experience it sounds like your router may be the problem, either that or a cable is loose, but I highly doubt that as you can still see PC1 from PC2.
Try disabling the network, then reabling. If that works then you're set. If not, then try to go into Command Prompt on PC1, do this by clicking Start>Run...>type in CMD. Now in CMD type in ipconfig /all . You should see a bunch of info. Now go back to PC2 and do the same thing. Look at both results and see if they match up.
Also, if you want you can try a program called WinXPfix. Type that into google and find the relavent result. Download it onto PC2, then run it. It should completely fix your problems. If not, then get back to us. Also, try posting your ipconfig /all results.
