set domain name

["Andrew Critchlow" <a_critchlow@hotmail.com>]

What's the best way to set the local domain and a debian server?
Also, eveytime I change resolv.conf it gets changed back to something else, could this be because there is a dhcp server running and the interface is configured to accept dhcp?
