Cable Network Problem

This problem is unrelated to VB but thought someone could help:

I recently setup a LAN between two PCs using ethernet cards. The LAN was working correctly with file and printer sharing available. Next I installed a RCA cable modem onto the LAN, using the uplink port on the Linksys switch. The driver for the modem was installed on the PC running Windows 2000. I
then installed the Comcast @Home software into the PC.

At this point both the cable connection and LAN were working. However the second PC, with Windows 98, couldn't use the modem. I registered with Comcast @Home for a second IP address for this computer. Next I ran the Comcast @Home installation software on the 98 machine. During the installation the PC crashed and the LAN connection was no longer working. The adapters seem to be both working and the switch has the correct lights on. Under the Workgroup icon only 1 PC is listed in each machine. What can I do to get the LAN working again?

do this

get a hub
get 4 straight cables


in the win2k machine
put 2 networkcards in it
hook your @home modem to one (use one of the straight cables)(make internet work on this one first)
then put second straight cable in the SECOND network card on your win2k machine
then take this into the HUB

other 2 machines

have a network card in each
and take 2 left straight cables and hook these 2 other machines to the hub

(you dont need to have another ip)
set ALL ips to automatic
oh ya
and DDDDDDDDONT use @home software
its crap

*by the way, thats how i have set up my network*

I agree the Comcast software is crap. I'll try your setup but I can't even get the LAN back up.
