Anir, Answers/comments: 1. Security - If you setup it up properly/apply all security patches and are behind a firewall you should be fine. Doesn't matter if you are using Linux, Windows, or anything if it's not configured properly it won't be secure. Also, if you are a business (even the smallest) a $500 Cisco PIX or similar firewall is not much to invest for some protection. 2. Two NIC cards - Configure the same way you do with the Linux box (that's if you are using the Windows server as a proxy as well). One for local and one for external. Likewise, I'd advise you to spend a few bucks on a good Windows 2003 resource book and start there. Every single one of us took the same path you did....good luck.

If so, have you created a RUS for this domain? ________________________________ From: Rusty P.
