Dynamic dns records not updating

Hello, We have started to have lookup problems in out network.

When a new client gets an IP address, DHCP doesn't update DNS with the record. The DHCP and DNS are on the same box (which is also the primary DC).

This results in an 'A' record owned by either 'system' or the PC's AD computer account.

When this happens, the 'A' record becomes unwriteable by the DHCP server due to its security settings.

For Windows 2008 and all newer operating systems, IPv6 must not be disabled.

If disabled, it will cause other problems: The Cable Guy – Support for IPv6 in Windows Server 2008 R2 and Windows 7, by Joseph Davies, Microsoft, Inc.

I have checked the event viewer logs for the DHCP and DNS server but nothing is present?

Hi Everyone, I have a 2003 AD DC running DNS services.

After having upgraded a Windows Server 2003 Active Directory Domain to Server 2008, and upgraded client PCs from Windows XP to Windows 7, I'm seeing inconsistent dynamic DNS update behaviour. If the machine’s DNS is statically configured: – It must only point to the internal DNS – It must be joined to the domain in order to authenticate using Kerberos to update. If statically configured and not joined to the domain, the client can’t update if the zone is set to Secure Only. For non-joined domain DHCP clients, you can configure DHCP to update in lieu of the client updating into a Secure Only zone. For any non-Windows statically configured machine, it must support the DNS Dynamic Updates feature and the zone configured to allow Secure and Unsecure updates. If the DNS server is multihomed and not configured properly to work with multihoming, it may cause problems with Dynamic Updates. If the zone is single label name, such as ‘domain’ instead of the proper minimal format of ‘domain.com,’ ‘domain.net,’ etc., it will NOT update. The client will "look" for the SOA of the zone when it attempts registration. For AD Integrated Zones and Secure Only Updates: a.The default setting appears to be Dynamically update DNS A and PTR records only if requested by the DHCP clients.(This is under ) Is there a downside to selecting Always dynamically update DNS A and PTR records?
