M 1056 Warning Microsoft-Windows-DHCP-Server System 11/2/2016 8:21:47 PM
The DHCP service has detected that it is running on a DC and has no credentials configured for use with Dynamic DNS registrations initiated by the DHCP service. This is not a recommended security configuration. Credentials for Dynamic DNS registrations may be configured using the command line "netsh dhcp server set dnscredentials" or via the DHCP Administrative tool.
M-DC1 1046 Error Microsoft-Windows-DHCP-Server System 11/2/2016 8:21:51 PM
The DHCP/BINL service on the local machine, belonging to the Windows Administrative domain m.local, has determined that it is not authorized to start. It has stopped servicing clients. The following are some possible reasons for this:
This machine is part of a directory service enterprise and is not authorized in the same domain. (See help on the DHCP Service Management Tool for additional information).
This machine cannot reach its directory service enterprise and it has encountered another DHCP service on the network belonging to a directory service enterprise on which the local machine is not authorized.
Some unexpected network error occurred.
M-DC1 10020 Warning Microsoft-Windows-DHCP-Server System 11/2/2016 8:21:51 PM
This computer has at least one dynamically assigned IPv6 address.For reliable DHCPv6 server operation, you should use only static IPv6 addresses.
I do not know how to create an ipv6 address to assign
Both both the SBS2008 and the server 2012 have the option to deauthorize when DHCP console is brought up
I do not want to deathorize sbs until I am sure that 2012 is ready to function as DHCP server without any errors or warnings
