For some daft reason, someone in the past set up two of our school IT suites (Music and Media Studies) on different physical networks, with their own unique server and domain name. I'm wondering if I'm letting myself in for any problems if I connect them up to the main network by patching the relevant network switches. (These rooms aren't even on the Internet at the moment.)
I've been warned that I should disable DHCP on these extra servers in order to stop them spreading IP addresses from their own strange ranges onto the rest of the school, but are there any other nasty side-effects I should be aware of...? (At some point I need to integrate them all properly, but at the moment I'm just looking for a quick fix to register some new music software via the Internet without repatching individual PCs. Everything's Windows Server 2003 / XP clients.)
