Xp pro and 98se really dont seem to like being networked together, or it might be me

.
When i first networked the two pc's together using a cat5e crossover cable, set the workgroups the same the 98 machine could see the shared folder and connected to the internet.Then when i took Norton antivirus and Personal firewall 2002 off and put 2003 on the 98 machine could no longer see the newtwork but could connect to the net.I took 2003 off, as stuff seemed to runn a bit slower with 2003,i cleaned the reg of any norton stuff and put antivirus and personal firewall 2002 back on and the 98 machine could'nt use the net of see the network.Ive disabled the firewall see if that is the problem and the 98 machine still cant see the shared folder.
My bro had a fidle with PFW and under internet zone control and add the 98 machine and it can now use the net.( the first time i had 2002 i didnt have to add it to trusted). But it still cant see the network.
So i dont think it has much to do with Norton as the same happens with it on or off.
So any ideas or is it XP and 98 dont network well together ?
