dns records not refreshing
"r" <none[ at ]none.com> 5/11/2007 4:00:52 PM
Running AD with all DCs at Win2003 SP1. I was reading up on scavenging
since we need to enable this on our domain. I read that computers with
static IP addresses might not get there dns records refreshed so scavenging
could delete them (all of our servers have static IP addresses). I enabled
the advanced view on my mmc and checked a couple of the record time stamps
and found some alarming information.

1. Some of our servers had time stamps that were 4-5 months old, even though
those servers have been rebooted since then.
2. Some PCs on DHCP had very old time stamps also.

Are these time stamps correct? What can account for the records not being
refreshed?

Thanks.

Default is the records are refreshed every 24 hours by the DHCP client
service, which is responsible for DNS registrations, even on static clients.
Check that the DHCP client service is running on all servers and
workstations.
