I have two servers, dell2650 with one running ad, dns, dhcp terminal services and some user programs. the other server is just for one specific sql 2000 multi user program (timematters). I set the system up but I am no expert, and just now see that the sql server is also a domain controller. I did not intend this, and am considering demoting it, but don't know if I should or not. what are the pros and cons of only having one domain controller vs two?
