How to block all Internet Access ???

[jtice]

I need a simple way to block all programs on my business workstations, from Internet Access.

I read up alittle on the XP firewall, but it says not to use it with a LAN, becuase it can effect file sharing.

I need the users on the LAN, sharing files, printers, etc.
But, I need them to be totally blocked from the Internet.
Not just Internet Explorer, But a complete block from the Internet including all programs.

Thanks

dude, go here and read this, you can also remove TCP/IP from all your computers on the LAN. W/O TCP/IP on the boxes, no internet, period, and you can SYS ADMIN that, so no one can reinstall it, or permanently remove it.
