Windows clients not updating dns
As stated above Windows clients typically refresh their address even if nothing changed, so our update code would run unconditionally, too, based on timed events.
During design discussion, it was decided that the new options should be not include the provider-specific prefix but rather be provider agnostic to ease sharing the code and possibly allow other providers to use dynamic DNS updates as well.
To be able to detect if the resource record is stale, every dynamically created RR in the Windows DNS has a timestamp that is updated with the dynamic update if scavenging is enabled.
Manually created DNS records do not have a timestamp.
Optionally, for machines that use IP aliasing or setups that wish to update both IPv4 and IPv6 addresses of an interface at the same time there will be an option .
Contrary to IPA dynamic DNS update that generates the PTR record in the bind dyndb plugin, AD wouldn’t update the PTR record on its own when only A/AAAA record is updated.
To be able to keep the forward and reverse zones in sync, the AD dynamic update message would also include updating the PTR records.
(I hope that’s crystal clear – you would be surprised on the number of responses I get asking if the DHCP credentials should be in this group.) You Just to be crystal clear, this means that if the lease is an 8 day lease, than NOREFRESH should be 4 (four) and REFRESH should be 4 (four) so when you add them together, they are not greater than the lease length.This section provides a brief overview of how Windows clients may update their DNS records and how scavenging is configured and performed in a Windows domain.For more complete information, please follow the links at the bottom of this page.This is because DHCP doesn’t own the record, the client does, even though DHCP registered it.The way to get around this is you can configure DHCP’s Option 081 to update the record for all client, no matter if the client asks or not.
