Gameing/File sharing problem on network

I currently have 3 computers connected to a Di-604 router. Two run XP and one runs windows 98.

All three computers can easily connect to the internet through comcast high speed internet at the same time, but file sharing doesnt work between the two xp computers and I havnt tried it on the 98 computer as its rarely used. Xp computer 2 can see the computer in the workgroup, but cannot acces computer #1 because it says he needs to contact system administrator even though computer 1 is sharing. Also, if I make a LAN game, the person on the other computer cannot see it and we cant join the same internet game.

XP #1
ip as whatismyip.com says 24.118.121.197
ip assigned by DHCP 192.168.0.101
subnet mask 255.255.255.0
Default gateway 192.168.0.1

XP #2
ip as whatismyip.com says 24.118.121.197
ip assigned by DHCP 192.168.0.101
subnet mask 255.255.255.0
Default gateway 192.168.0.1

Please, we really need to be able to play games together online, any help would be greatly appreciated.

Ill second that comment.

You can set the router to be the dhcp server by setting it in the options. You will need to set each computer to obtain ip numbers automatically. You can do this under internet options. Or do what was mentioned before.

Start>Control Panel>Network Connections
Right-click your LAN connection>Properties
Internet Protocol(TCP/IP)>Properties
