Active directory dhcp not updating dns
The DHCP server registers Windows clients’ A RRs and PTR RRs with the dynamic DNS server on their behalf.
When an update triggers, the DHCP server updates both the RRs for the client.
Since there is no dynamic reverse lookup zone, the registration fails, but the DHCP database cleanup, performed every 60 minutes, attempts the registrations that previously failed.
If the client has moved to a new IP subnet, the the A record is registered using the old IP address.
Although all versions of Win2K clients automatically benefit from dynamic DNS updates, Windows clients (Windows NT, Windows 9.x) take advantage of dynamic updates only if a Win2K DHCP server is available to service them.The clients use an FQDN to register their IP addresses.For example, the FQDN of a computer named Mars in the domain sales.will be mars.sales.If you configure a Primary or Secondary zone, the DNS database is stored on the hard disk in a zone file, which is a plain ASCII text file (e.g., dns).By default, Win2K doesn’t configure a standard Primary zone for dynamic updates.
