HELP - Can't connect to Internet with TCP/IP

[Storm]

I have 3 PC's that will not connect to the Internet through my Novell LAN.
All 3 log into the network fine
Here are the stats:

ISDN line
Novell 4.1
1 PC on Win98
2 PC's on Win98se
All 3 with 3Com nic cards. (1 has older card)

Steps taking:

Removed all TCP/IP and reinstalled.
Removed all network drivers and reinstalled.
Reinstalled Win98 over itself.
Using "netstat" at DOS prompt shows nothing.
Pinging shows nothing.
Have been drinking mass quantities of coffee!

HELP!
