On our small corporate network (a few hundred client pc's and 4 servers), both our DC's (Win2k Server) have SQL Server running for various apps. One DC is also our print server for the network, 20 or so printers - 8GB spool drive, the server antivirus server, and our file storage server for roaming profiles and personal storage. The other DC is also our RAS VPN server with ~40 connections at one time all day, and our email server which includes the email handler (Imail 8.05hf3), the email anti-spam (ASSP) and the email antivirus gateway (Interscan). Handles 3500 emails in and 500 out daily with a few hundred virus laden emails and 50% spam running an average ~10% cpu with rare spikes approaching 100% but usually less than 70% and commonly dips down to 0-3%. I agree with your ideal, but economics dictate that we use our DC's for more than just AD. We are not having any problems running other applications and services on our two domain controllers.
