Effects of Clients w/o DNS Host Records in Active Directory

[mojoxp]

So I had this brought up at a meeting today, and I didn't know the answer: if I have an Active Directory Domain, and the DNS records for all of the Domain Controllers and Member Servers are correct, what will the effect be if the client workstations don't have host records ie: dynamic updates were disabled and there wasn't a host record created for it manually or by the DHCP server?

I know that you won't be able to access the machines remotely except by IP, and alot of things like SMS won't work... but is there anything else?
