Dhcp lease not updating dns
Interestingly, I picked another one which I believe to be in-date, and the service account was present.I'm wondering if I remove all records which don't have the service account present, will these then be regenerated correctly, and updated properly going forward? I've picked two records that are out of date - the owner is SYSTEM.I'm wondering if I remove all records which don't have the service account present, will these then be regenerated correctly, and updated properly going forward? You can try deleting some of the outdated records, and then either let DHCP refresh the records or do an ipconfig /registerdns from the client. You still should be looking at why scavenging is not running in your environment.All records with a timestamp of today (specifically the two machines we just rebuilt) don't have the service account in the permissions - they do have their own computer account, and the owner is SYSTEM.I did a bit of reading and discovered that the group should have DNS computer accounts in, if the zones are configured to only be updated securely - which they were. I am forever getting incorrect / outdated lookups when connecting to machines.I also read that a service account should be configured to carry out the zone updates - which I have now done. Our domain's zone is configured as an AD-Integrated zone with replication to all DNS servers in the forest.At the same time, I'm combing through AD and rationalizing group memberships.
I also noted a staggering amount of old, outdated DNS records.
Is it the computer account of the client (PC123$), the DHCP server, or the service account you configured?
Because secure updates are enabled, only the owner of the record can update it.
DC1 has DNS servers setup as itself and DC2 (primary and secondary)DC2 has DNS servers setup as DC1 and itself (primary and secondary) Do you have an account set up as proxy for the DHCP server to register users?
The DHCP service needs some valid way to tell the DNS server to update the records.
Our DHCP was set to lease addresses for 1 day, for reasons which were never explained to me.
