I've got 3 comps including this one with XP(SP 2)
'n 98SE(without any updates) on the other two.XP is connected to
cable internet.So I've got 2 NIC on this machine since this is the ICS
host computer.

However, I cannot share the internet
using the network setup wizard or manually
but I can share the files 'n printer.
Im using the standard patch cables with RJ45
connectors along with a switch to connect
the comps on LAN.

I've tried some online tutorials but they are somewhat
different than one another and never really helped me
out.

This is what I've done till now.
First of all I've renamed the two Local Area Connections in
My Network Places to LAN(for local network) and WAN(for Internet)

For the NIC that is connected to the internet the TCP/IP
parameters are provided by the ISP.In the General tab of WAN following
things are installed:
1)Internet Protocol(TCP/IP)
2)Client for Microsoft Networks
3)File and Printer sharing for Microsoft Networks

Then in the Properties>Advanced tab of WAN I enabled "Allow other
network users to connect thru this computers internet connection" as
well as "Allow other network users to control or disable the shared
internet connection".

The General tab of the LAN properties also got the same 3 things
installed with the IP as 192.168.0.1 'n Subnet 255.255.255.0
For the other 2 pcs I've set the IP addresses to be obtained
automatically.All the pcs got the same workgroup name.

Plz help.
