    Hello Peeps,

    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
