Not sure if this would work, but you can try.

Make sure that none of the users have administrative rights so that changes you make can't be undone.

If your router handles the IP addressing for each device using DHCP, determine the IP address for each computer you DON'T want to access the internet (using the ipconfig command)

Let's assume the following for just 1 computer

IP address--192.168.1.2

Subnet Mask--255.255.255.0

Default Gateway--192.168.1.1

Go into the TCP/IP properties of the computer on that network connection and set it up for manual IP address and DNS servers and use the following information:

IP address--192.168.1.2

Subnet Mask--255.255.255.0

Default Gateway--NONE

DNS Server--192.168.1.1

By not putting in a default gateway (which is the IP address of the router by the way) the machine will not be able to get off of the LAN, thus no internet access. By using the IP address and subnet mask, it will still have access to the LAN and by using the router as a DNS server, it can still use hostnames to resolve IP addresses inside the LAN.
