I am not very computer savvy, but hopefully I can explain this problem. I have two computers. One is hooked up to high speed inernet - Windows XP. The other is not - Windows 2000. Both have Network cards. I bought a cable that connects the two. I remove the high speed internet cable from the one computer and use this other cable to create a LAN connection between the two computers. I was successful in creating a network and my son and I have played DOOM and Quake in team multiplayer mode (TCP...). Then, I got too many viruses in computer One and I was advised to completely wipe out the hard drive and reinstall WIndows XP. I did. I thought I set up the network again the same way but now it doesn't work. Here's what happens. I connect the cable, both computers load up the game. On the multiplayer screen, I will set up a game on Computer One. Computer Two sees the game it needs to join from computer one. But it never connects. If I go the other way and use Computer Two to set up the game, Computer One doesn't even see the game to join. So there is communication going on, but something isn't right. On Computer One, when I'm trying to connect to play the game, I can see the computer struggling to acquire an IP address, it then goes into the "limited or no connectivity" mode. When I try to repair it it looks for a network address but still comes back with "limited or no connectivity" and tells me to see the Netork Administrator, me!!! The network neighborhood shows the two computers in it and the names I named them. We used to play fine, and I have tried to set up the home network with the Network wizard many times and the result is the same. I may be doing something wrong, but I think I remembered how I set it up the first time. Please offer suggestions. Which computer is the problem? Could it be computer two? Thank you.
