Microsoft dhcp server not updating dns
I’m not sure how often that bind rewrites these files, but at least it seems to always happen when you stop the bind service.
Before continuing These steps assumes that you already have a working copy of dhcp3-server and bind9 installed.
If you have the DHCP service installed on your domain controller without a service account configured, by default, DNS registrations from DHCP clients will be prevented from being registered and will log event 1056 in event viewer.
Solution: Complete the following steps below to change the credentials of the service account used for DHCP.
OK Every half hour the lease will try to renew by machines itself Because generally client will try renewal after half lease time elapsed Now Even if you keep No refresh (1 HR) refresh (2 HRS) = 3 HRS, scavenging will run every 3 HRS and it will delete records older than 3 HRS Most of the records are updated every half an hour, hence scavenging will not delete most of the records Is there any specific reason for keeping such a short duration, if you could please explain... Please set your DHCP advanced DNS options as below so that your DNS records will get updated Also add DHCP server to DNSUpdate Proxy Group on Domain Controller (DNS Server) You already have set credentials in DHCP console Mahesh I inherited the setup and am in the process of trying to clean up some of the previous admins configurations. The DHCP lease times have been reduced to 1 hour for each VLAN.
The reason I suggesting you to not keep such a small scavenging period is all SRV records may get deleted if they do not updated within 3 HRS What is the frequency of DHCP client in out ? The devices are moving constantly as team members go from desk to conference and desk again. The changes seem to be making a difference in the DNS clean up.
