Dhcp dns updating affairdating
The DNS Client service performs this function for all network connections on the client, including any that are not configured to use DHCP.
When a qualified DNS client (such as a computer running Windows XP Professional or Windows Vista®) issues an update, DHCP servers running Windows Server 2008 process the update to determine in which of three ways the server will initiate updates on behalf of the client: The ability to register both A and PTR resource records enables a DHCP server to act as a proxy for clients running other operating systems, such as Microsoft Windows Millennium Edition, or Windows 98, for the purpose of DNS dynamic update registration.
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.
When a DHCP server registers and updates DNS pointer (PTR) and address (A) resource records on behalf of its DHCP-enabled clients, it uses the information contained within an additional DHCP option: the Client FQDN option (option 81), which permits a client to provide its FQDN and any instructions to the DHCP server that is used to process DNS dynamic updates on its behalf.
Would appreciate any pointers on getting this to work.
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.
Dont have a router there, only a 3750 tied in via a fiber link.
Had to troubleshoot a workstation hogging bandwidth.
Using Netflow, I could see the ip address of the offender but couldnt see the hostname of the computer/workstation that was the offender.
