Enable Dynamic DNS Update on WAN MiniPort
Posted December 18th, 2008 by Matt ShadboltI’ve been planning an upgrade to Windows Essential Business Server 2008 lately and before any migration can proceed you have to run the Server Preparation Wizard. This Wizard checks the health of your environment – such as the domain functionality level and the DC’s service pack level. One interesting error that I received prompted me to resolve an issue with the Dynamic DNS update status of a WAN MiniPort (IP). The error is as follows:
Error: Dynamic DNS registration is disabled for the WAN Miniport (IP) (MAC address: 00:11:22:33:00:00) internal network adapter on the SERVER.domain.local server. See also: KB 816592
The WAN miniport is a virtual interface that the server uses for Routing and RAS. As it isn’t a physical interface on the server, there was no where to enable the Dynamic DNS update like a normal network connection. However, there is a fix!
Warning: Changes to the Registry can cause major issues. Be sure to back it up first.
Open the registry editor (Start > Run > regedit) and browse to the following path:
HKLM> SYSTEM > CurrentControlSet > Services > Tcpip > Parameters > Interfaces
Now you need to find the correct interface. The RAS interface should be registered in your DHCP leases so open the DHCP configuration and find its IP address. Once you’ve got the IP address, browse down the list of interfaces (they should look like {5w11g5s4re8s5s26s8d4f3w8e7r} etc) and find the interface with the key DhcpIPAddress that corresponds with the IP you found in the DHCP console.
Now right-click on the RegistrationEnabled DWORD and choose Modify. Change the HEX Value Data from 0 to 1. This tells the virtual interface to dynamically register the name. You can now force the interface to register by running the IPCONFIG /REGISTERDNS command at a command prompt.
If you now re-run the EBS Preparation Wizard you will find that the error disappears!
