Dhcp server updating dns records

The Windows 2000 DNS service supports dynamic updates.

For more information, see the chapter "Windows 2000 DNS" in this book A Windows 2000 DHCP server can register with a DNS server and update pointer (PTR) and address (A) resource records on behalf of its DHCP-enabled clients using the DNS dynamic update protocol.

Would like to see about getting DHCP configured on a Cisco switch to auto-register the computers hostname with a MS DNS server.

Had to troubleshoot a workstation hogging bandwidth.

Dont have a router there, only a 3750 tied in via a fiber link.

I have been looking at the Cisco docs for getting this to work but nothing yet.

For some reason DHCP leases are not registered in either DNS server.

Even when registering DNS on the client, nothing is added on the DNS servers.

Here is my config for DHCP on the switch -ip dhcp pool PC network 10.1.70.0 255.255.255.0 domain-name dns-server 10.1.1.1 10.1.1.2 default-router 10.1.70.1 lease 8This is an office across the street from the main building.For example, a client may acquire its IP address from a DHCP server, but the DNS records would not reflect the IP address acquired nor provide a mapping from the new IP address to the computer name (FQDN).In Windows 2000, DHCP servers and clients can register with DNS to provide this update service if the DNS server supports DNS with dynamic updates.When you do this, you must use an additional DHCP option, the Client FQDN option (option 81).This option lets the client send its FQDN to the DHCP server in the DHCPREQUEST packet.
