Microsoft dhcp server not updating dns

If implemented, the DHCP server can dynamically update DNS to modify an individual computer's resource records with a DNS server using the dynamic update protocol.

This DHCP option permits the DHCP server the following possible interactions for processing DNS information on behalf of DHCP clients that include Option Code 81 in the DHCPRequest message they send to the server: DHCP and static DNS service are not compatible for keeping name-to-address mapping information synchronized.

Billy Also: This happens in cases where the client machine is not joined to the domain and has a missing or different suffix than the zone in DNS.

See the attached image for what I see in my DHCP manager. The pen icon means "Active lease, DNS dynamic update pending.

If this is the case, go into the client machine's IP properties, and on the DNS tab in TCP/IP properties, clear the "Register this connection's addresses in DNS" as well as the "Use this connection's DNS suffix in DNS registration" check boxes, the DHCP Server will fill these in for you and register using the domain name.

If your DHCP servers are Windows 2003 or WIndows 2008, Configure a dedicated the user account you created as credentials in DHCP by going into DHCP COnsole, DHCP server properties, and on the Advanced tab of the DHCP Server Properties sheet click the Credentials button, and provide this account info.

DNS maintains (among other things) information that links a computer's fully qualified domain name (FQDN) to its assigned IP address(es).

While DHCP provides a powerful mechanism for automatically configuring client IP addresses, until recently DHCP did not notify the DNS service to update the DNS records on the client; specifically, updating the client name to an IP address, and IP address to name mappings maintained by a DNS server.
