Keep in mind that while I really enjoyed Windows 2000 for many many years, it was left with an unpatched exploit. Here it is -> http://secunia.com/advisories/product/1/?task=advisories

This server must NEVER BE EXPOSED to the internet and possibly not to a company network. It may be possible to place a firewall to block ALL ports except which are needed and NEVER ALLOW anyone but the admin on the console.

Best of luck!
