Need more info.
Is this WS tied into the main servers, or is it a standalone that logs on a couple times a day to upload data?
Is there a firewall/router between it and the servers, or between it and the Web?
Any 'NetNanny'-type of app can block all but a select group of URLs. That may work if the purpose is to block staff from surfing pr0n on the company's time...
For more security other steps will be needed also. For one thing, you could install a keystroke logger to document all inputs made on the workstation.
