Two XP Home PC network. One PC cannot see the other on workgroup
My roommate and I both have PC's running XP Home. We both hooked into my router to start a lan (which we done before) for playing games together. His system has just been restored. New XP Home install. Now when we hook into the router for network and both run the network setup wizard, I can see him on the network but he cannot see me. He can access the internet fine when we plug him back into his modem. My XP firewall is not currently turned on(at least last I checked because it seems Windows update sometimes turns it back on against my wishes) and his was on but I tried turning it off with no better luck.
I am going to try this fix for now:
