Overscavenged DNS, now I need to repopulate.
Posted on 2006-04-19
Our DNS had many records incorrect, as DHCP was and apparently is not updating records properly when IP addresses changed. I shortened the leases for DHCP and shortened the scavenge interval for DNS to clear out the records, but apparently went too far. I need a way to repopulate DNS from DHCP without having to touch all the workstations in my environment. I have a current list of computer names and IP addresses, and DHCP is also current. I would prefer not to maually update all the records individually. Also, if anyone has an idea on how to ensure that DHCP keeps up with workstation name/address links in the future I would appreciate it. DHCP and DNS are both running on the DCs (Win2k3 sp1). The DHCP lease interval is currently 5 days, and DNS is set to scavenge stale records, the no-refresh and refresh are 1 day, and the automatic scavenging is set to 10 days.
