You can have them be the same, but you have to setup a "split-brain" DNS. Unless you have some specific benefit you will derive from using the same domain name, then I would agree with the other responders: use a ".local" or somesuch for your internal.

We are having discussions to decide on a new internal domain name. I know that years ago, it was best practice to have a different internal domain name from your external domain name, which is what the Novell guy is holding onto, like a pitbull to a mailman's leg. Is that still true today? We are on private IPs internally, so external forces can't route to the inside anyway, so my thinking, and the other Windows admins, is that having the same FQDN internally would be ok.
