Man, Give Redhat a shot. Good hardware detection and administration tools. Slackware is becomming the bastard child, it would probably be the very bottom of my recomendation list.

For mail, Courier MTA is a excellent package. Also, it will build RPM's out of the tarball with one command. I beileve they are introducing a spam package, but I just use the BOFH filters and blackhole relays and IP blocks I dont like.

You can read NTFS, don't try to write to it unless you like scrammbled eggs.

"DHCP Server"
personally, I statically define all my IP's. I stoped using that some time ago, do you really NEED it?

Pretty much everything here would run better on linux. Expecially the web hosting end of it. And once you get the hang of it, administration from the command line is MUCH nicer and effiecient.

If your really stuck, get with me one day, and I will try to help. If you can get a Redhat (for what your doing, I would recommend 7.3) system online, I can shell to it and we can share a screen session so you can see how its done. I can't promise to be your personal admin, but I wil offer to get you rolling.
