Problem configuring ICS in 2003 server

When I try to configure Internet Connection Sharing in 2003 Server I get this error message

A LAN connection is already configured with the IP address that is required for
automatic IP addressing

I presume that it relates to ip 192.168.0.1 but there are only 2 PC's and one router
The set up is

Server network cards
LAN   ip:192.168.0.20     mask:255.255.255.0  
External  ip:192.168.0.21    mask:255.255.255.0    gateway:192.168.0.2(router address)

PC1
PC network card   ip:192.168.0.3    mask:255.255.255.0  running Win XP
PC wireless network card   ip:192.168.0.4   mask:255.255.255.0  disabled
PC bluetooth adapter   ip:192.168.0.10   mask:255.255.255.0

PC2
PC network card   ip:192.168.0.5   mask:255.255.255.0  running Win XP

The server only has the File server Role running at the moment (Still Learning)
I can connect to the internet through the server
I can access the network with both pc's with no problems

Help!

First thing: You need an router not an ICS.
Second: change your IP from internal LAN to 10.0.0.1-server, 10.0.0.2-PC1, 10.0.0.3-PC2.
Then configure the routing and remote access service on the server for Network router without NAT. For Gateway on all LAN computer except the server use 10.0.0.1, and for DNS don't change settings. Do not change anything on External network settings.

Good luck
