Dynamic DNS, DNS Records & Scavenging

Hi there,

I posted this on the Server.general newsgroups but not heard anything back.
Probably isn't the right newsgroup really. Thought i would try here to see
if anyone can help;

We have an issue whereby we want external clients to register there VPN IP
addresses in DNS. The VPN connections are handled by a RAS server which gets
the IP addresses from DHCP. There are two DHCP Servers;

DC01 DHCP,DNS, Domain Controller

Server01 DHCP,DNS, Domain Controller

Server02 RAS

Both the servers are set to update A and PTR records for clients. In DNS
however this doesn't seem to be the case. I then added DC01 to the
DNSUpdateProxy and when i did this i saw my test laptop register its ip in
dns. I then disconnected and reconnected and got a different IP address. the
ip address i got then was one which was already associated with an A record
for another computer but the lease for the IP had expired hence why it was
assigned to me. With the DHCP servers there are no overlaps in the IP
address scopes. Do you think the A record for the other computer is stopping
my system from registering a DNS record?

Please note that there is no scavenging turned on at the server or the zone
levels.

David.
