Prevent Outside Internet, But Allow Local InTRAnet

My company is going to a very large datacenter owned by our parent company.  Over the last 2 years with Windows 2003 Enterprise, I have been running 14 Thin Clients using Terminal Services.   These Thin Clients are out on a factory floor, and sort of hard to monitor against the employee's abusing and constantly getting online.

Not calling them dumb, but to prevent the employees from using the internet, I simply tricked IE and set a Proxy setting, even though I don't have a proxy.

Now that we are going to a Corporate Data Center, the employees will HAVE to access IE, because of the fact Corporate Uses Sharepoint.   How can I allow them to ONLY access a local Address (192.168.1.*) and NOT the outside world Internet.

    Option A:  Buy a proxy server to control this...  

    Option B:  You can use your same technique, but in IE settings, you can select the option to BYPASS the *fake* proxy for LOCAL addresses.  IE Settings --> Connections -->LAN Settings --> place a check mark in bypas proxy for local Addresses.   If this doesn't work, you can add an exception on the Advanced tab and add the URL for the Sharepoint server.

    The above is probaly the best of these options as you can still allow access to your sharepoint site and company INTRANET

    I really liked that PortLock software.  It made everything pretty easy to use.  I installed the 30 day trial on the Console, and it worked well.

    NJComputerNetworks idea was a little more economical however, and worked out well.

    Thanks for the advice!!
