I install linux samba servers at clients and can login from anywhere in the world securely, check processes, connections, view logs, and best of all my systems never go down. I prefer turbolinux 6.5 server, although the new 7.0 is a little bit more updated. Try it instead of windows NT or 2K. I also like webmin.com web based gui for admin sometimes.
Also it is $2000-$7500 cheaper than the MS licenses with clients. Samba needs no licenses, just a good tech.
