Well, I reinstalled XP today and it's working again (for now). My setup, lets see, Athlon XP 1800+, 256 MB ram, 3Com NIC, Norton Internet Security. How it's networked, standard home networking thing, the way the wizzard set it up. Host IP 192.168.0.1, client is dynamic now, I usually assign it to a static IP. I don't know what started going on with my system, it worked great for about 9 months. It's just been the last 2 or 3 months that it has been giving me headaches. As long as this new installation doesn't mess with me, I will be happy for a while I guess. What other information would you need? I would like to attempt to discover the root cause of this problem sometime. Thanks.
