Actually, you're not close. For $179/year, you get the basic EW
subscription. This has no server tools - no bind, no dhcpd, nada. It's
a desktop.
Are you sure on that. I don't think I've seen a linux distribution
without mail, DNS, http, samba, NFS, or DHCP in years. I cannot get in
to check the SRPM list for EW right now.
But, asuming that EW doesn't come with those apps. How much is it going
to cost to add them, using the Red Hat SRPMS? How much to add them to
Windows? Can you even add them to Windows? Does XP have an NFS, bind,
and dhcp server available?
