Hi Dave,
We run CCC on Win2K in an SBS 2003 environment. As far as I know MSDE doesn't care about what it's installed on. And, as far as I know, you can add as many servers as you want to on an SBS 2003 network, as long as you have licenses, don't exceed 75 licenses, and don't have more than one domain. See the "Networking and Security" Section at
http://www.microsoft.com/windowsserv...eneralfaq.mspx
for details.
I'm not willing to put anything else on the CCC server, though. It hangs every four months or so. (We've had it for 12 months, and we've had the SBS2003 environment for 2 months. It hasn't hung in the past two months...)
Regards,
Carl
