holistic dating agency - Dhcp clients not updating dns records

That doesn't exactly seem to be the case from your experience, but might be close.... Massimo, are you able to pull a wireshark trace and check the DHCPREQUEST Packet?

What this means in practice is the following: This means the DHCP server computer account will own certain records in DNS, such as the PTR records and even some A records for older hosts.

(However, it's unlikely that you would have many NT 4.0 hosts in your environment.) This can cause the following two problems: For this reason, DHCP servers could be added to a group called Dns Update Proxy.

This user's credentials are used in the Advanced - Credentials setting of the DHCP zone.

What I am finding is that workstations that are joined to the domain are showing up in DNS just fine, while workstations that are not part of the domain do not show up in DNS - however they do show up in DHCP.

Dynamic DNS is a feature that allows hosts to register their records in DNS, thus removing the need for administrators to manually create records.

In addition, Secure Dynamic Update can be required for zones that are Active Directory-integrated (and should be required, per best practices), which allows only members of the Authenticated Users group to register records.

I've stumbled upon a strange behaviour with Windows machines, which seems to be fairly consistent between all Windows versions from Vista/2008 to 8.1/2012 R2; it doesn't happen instead when using Windows XP or Windows Server 2003.

The problem is this: when the network adapter is configured for DHCP and the DHCP server doesn't register DNS records on behalf of its clients (because it can't, or because it's not configured to do so), then A friend not on SF said: "That's normal, PTR is only updated by DHCP in Win2K ".

in the TCP/IP settings of the network interface: As much as it may appear strange, this is the only solution to ensure Windows will register both the A and the PTR records for a DHCP network connection; otherwise, it will only register the A record. sends option 81 and its fully qualified domain name to the DHCP server and requests the DHCP server to register a pointer resource record (PTR RR) on its behalf.

The dynamic update client registers an address resource record (A RR). the DHCP server can be configured to instruct the client to allow the server to register both records with the DNS.

I am having troubles with DNS getting updated when a new DHCP lease is handed out.
