DNS msdcs has only one entry, our former PDC - is this ok? Eventually we'll remove that server as a DC
We have recently moved the Primary Domain Controller role(s) from one of our domain controllers to another.
Other than a few bumps in the road, things have stabilized and seem to be working OK.
However, I've noticed something in our DNS that puzzles me. In one of the msdcs items our former PDC is the only server listed.
See attached image for an idea of which msdcs item I'm talking about. You can navigate to it by going to:
DNS - <any DC> - Forward Lookup Zones - <domain.LOCAL> - _msdcs
There is only one item in this _msdcs section. It's 'type' is "Name Server (NS)", and the item refers to our former Primary Domain Controller.
My questions are:
1). Is it ok that this item lists our former PDC? (Instead of our current PDC).
2). If we dcpromo and remove the former PDC, will this object change automatically?
3). Should we manually edit this object right now? (and make it our current PDC)
4). Should there be more than one item in this _msdcs container?
I understand the general role of the _msdcs container in DNS, but this separate item in the <our domain>.LOCAL section is a bit of a mystery to me - I haven't been able to find resources that explain it's role/function.
Thanks for the help!

Thanks for the information. It would've been awesome to have a more thorough explanation of the "best practices" configuration for this item, but I understand that sometimes more in-depth learning/teaching has to take place with other resources (classes, manuals, training).
Thanks! -joel

Do you know if it's best practice to have more than one server listed in this container?
I'm not clear on what that particular container is for, so I'm hesitant to make changes without understanding it better.
