DNS A Records not being made

Hello,

Recently, We have noticed that when an IP Address is allocated to a user via DHCP, it does not automatically create a DNS A Record... This isnt for every host, it appears to be intermittent.

So when programs that rely upon DNS for host to IP or visa versa... Communication is failing.

If i manually do: "ipconfig /release" and then "ipconfig /renew" on the machine in question, the A Record is then created and the problem is solved... However, this is only a manual fix and we would like to find the root cause as to why these A Records arent being made automatically.

Also, i have found some event log errors on the machines that do not create A Records automatically...
The eventlog error is: "the system failed to register host (a or aaaa) resource records (rrs) for network adapter"

Thankyou

Hello Muhammad,
Thankyou for getting back to us... I have double checked and the client and server settings are already set as was in your pictures.
How about this one:

Hello Hypercat, thankyou for helping us with this...

However, all of the options in your picture are the same on our scope properties on the DNS Tab.
Have you checked the DHCP and DNS logs on your server?  I'm wondering if the security information for those workstations has been corrupted in some way to prevent automatic updating of the DNS records.  Also, does it renew automatically if you reboot the workstation?
