If your Server 2003 computer is the internet gateway, then you may disable other users internet access by the following:

Start>Control Panel>Network Connections: Right Click your LAN connection (Not your internet connection) and click properties.
Go to the Advanced tab, and uncheck the two checkboxes in the section titled "Internet connection sharing".

Hope that solves it.
Sorry, I thought you wanted to disable internet access to ALL users.
you can use IPsec if you want to block the internet access :

hope that help
