3 networked computers, only 1 internet access

ICS on the XP Pro machine - it has to share its intenet connection (enable this on the NIC properties in Network Connections).

We have: A desktop running XP Pro, which has access to the internet via adsl. A desktop running W2K these two computers are networked together with an Edimax 5-port switch. The switch also serves as a wireless access point (802.11g). We also have a laptop running XP Home with built-in wireless adapter (802.11b). All three computers can access each other on the network. Only the XP Pro can access the internet. We've checked all settings we can think of.... what haven't we thought of? Josie

Tried this after your suggestion. It's not that. Any more please?

ICS !!??

Check the network settings on the laptop to see if it's properly picking up the XP Pro machine as the gateway to the Internet.

Fraid that was one of the first things we tried....

Double click on the network adapter, and then the Support tab. The gateway IP should be set to the gateway.
