DNS dynamic updates - Secure vs. Nonsecure

[Ajay Kulsh]

Can anyone tell me what is the harm in having "Nonsecure" Dynamic DNS 
updates in Windows 2003 DNS server, if any? For some reason, from some of 
our subnets, clients (thru DHCP server or directly) cannot register their A 
and PTR records with the DNS server if we choose to have Secure Only 
updates, so we have enable both Secure and Nonsecure. Has anyone had this 
kind of problem before? Thanks.
