I had a 2003 (sbs) Domain. I added a 2012-R2-STD DC. Moved the FSMO roles to the 2012R2 server. Demoted and removed the 2003 SBS server.
I'm adding a second (2012Std) DC. I added "Active DIrectory Name Services" Role. When Promoting this server to as a Domain Controller I received the following Warning
"A delegation for this DNS server cannot be created because the authoritative parent zone cannot be found or it does not run Windows DNS server. If you are integrating with an existing DNS infrastructure, you should manually create a delegation to this DNS server in the parent zone to to ensure reliable name resolution from outside the domain "erateoffice.net". Otherwise, no action is required."
What does this mean? In general, DNS looks ok on the new DC.
Thank you in advance.
