We have a Windows 2008 that is multihomed. One nic is on the LAN, two NICS are iSCSI Nics that connect to our SAN. All Nics have static IP adresses. This 2008 server is a DC and does DNS. The iSCSI Nics keep registering themselves in DNS automatically. We've unchecked the option in the Advanced settings under TCP/IP, we've also added the registry key 'DisableDynamicUpdate' for the iSCSI adapters. The server is fully patched and has been rebooted after these changes, but it keeps registering the iSCSI adapters in DNS. We need it to only register the LAN adapter.
