Hi,

We migrated Server 2003 AD and DNS to Server 2008 R2 and later also configured DHCP on the new box. In the event log we keep getting below warning message upon DHCP Service restart:

"This computer has at least one dynamically assigned IPv6 address. For reliable DHCPv6 server operation, you should use only static IPv6 addresses."

Log Name: System
Source: DHCP-Server
Event ID: 10020
Level: Warning

We have disabled IPv6 via registry and also unchecked it on all network interfaces. When we do "ipconfig /all" in cmd we don't see any interface with IPv6 option.

How to resolve this?

Thanks and Regards.
