I'm noticing in our DNS Manager for our Windows Server 2008 R2 domain / dns servers, the timestamp is not always updating. It seems hit or a miss. All clients are Windows 7 Professional. I notice if I go on a machine and manually type in ipconfig /registerdns, then the timestamp updates on the DNS servers. Is this something I should be putting in the login script for our domain users?
I even created a GPO called DNS Client Configuration and the following is defined:
Primary DNS Suffix
Register DNS records with connection-specific DNS suffix
Register PTR Records
Dynamic Update
Registration Refresh Interval
DNS Suffic Search List
Update Security Level.
For our DHCP server we do have secure updates on and I created a special AD user that is defined dhcpupdsrv with a randomly generated 24 character password that never expires.
One group of PC's I see their timestamp is 5/14/2013, when those computers were installed. I think that location has static IP's but wouldn't the GPO cause this to update?
I want to enable DNS scavenging but I am afraid to do so until the timestamps are current.
