XP ICS Error! >:(( 500 Points.

Hy,

I have a lan LAN.

The first computer has 2 NIC's the first nick is connected to the calbe modem and it has the IP's provided by the ISP. The internet runs on this conputer very well.

The secound nick has the next config:
IP: 192.168.0.1
SM: 255.255.255.0

The secound NIC connects to a HUB with a streight-through cable.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The secound computer that runs WIN XP as well (the proffessional edition) has the next config:

IP: 192.168.0.16
SM: 255.255.255.0
GW: 192.168.0.1

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

When i try to set the "Allow other users to connect through this computer..." it gives me an error: Internet Connection Sharing (ICS) cannot be enabled due to an IP address conflict on the network. ICS requires the host to be configured to use 192.168.0.1.....

Both PC's have Windows XP Service Pack 2 Installed.

I tryed all the possibilities. What should i do????

Thanks a lot.
