Then you have to set up your server as a DNS Server by adding the serverrole DNS Server and configuring your zone like in this Windows Server 2003 DNS Server tutorial. It will be a little different from the Server 2008 wizard, but you ‘ll find out. Use nrajlich.dyndns.org (or whatever you have) as Zone name (step 5) and fill the ip of your other home in at step 9.
Forward port 53/udp at your servers router to allow incoming dns queries.
Never worked with DNS Servers before but I think it should work! 🙂
