connect to internet but not network

So ive got these two computers and they can connect to the internet but not to each other. they are on the same workgroup but when i try to access that workgroup (called simply WORKGROUP) under My Network Places it comes up this message:
Workgroup not accessible
A list of servers for this workgroup is not currently available

both comps are using Win2k Pro and are connecting to the net via DSL that plugs into a NetTopia hub. The ultimate goal is to get them to share a printer.

Can anyone help?

you usually want both your computers on the same subnet for windows networking to work.  getting two ip addresses from an ISP usually doesn't provide this, and if these ip addresses are dynamic rather than static, setting up a stable network is problematic.

a second network card in each computer with static ip addresses (192.168.0.1 and 192.168.0.2, for example) connected through a hub or a crossover cable is the best solution, in both simplicity and stability.
