Register cisco IOS router name in win2003 DNS server

I've been able to lookup dns names with domain-name and name-server
just fine, but when i checked the DNS records on the server i didn't
see the ip of the router. Is there a way that i can make the router
work as a workstation as far as DNS is concerned, so that it publicises
the hostname or any other string of my choice at the dns server?

Thanks alot for any help and thought,
Michael
