Why DNS scavenging doesn't work?
Posted on 2014-09-24
This is using MS Windows 2003 AD domain. There are 2 DCs, and 2 DHCP servers. I want to do the dns object ageing and scavenging so as old objects must be automatically purged. I read some articles in which they suggest that all 3 levels - server, zone and the A/PTR object have to be enabled for scavenging. The scavenging settings that I set were, in zone - both forward and reverse zones of the ad domain, set with 2-day and 1-day, for no-refresh and refresh, respectively. In server, I enabled the scavenging and set 1-day;
As for the 2 DHCP servers, I also ticked settings in the DNS tab; Besides this, I also run "netsh dhcp set server dnscredentials" with correct user name and password. This DHCP servers also joined as members of UpdateDNSProxy group. However, I check that the 2502 events are reported meaning none of the stale object is scavenged.
Any settings I miss out? How to troubleshoot and get the scavenging work?
