Demotion doesn't properly remove server from DNS

Hi, here the problem.

After a successful demotion, DCs' names are not removed from the DNS
AD-Integrated zones (Name Servers Tab). I've waited days to see if it was
replication-related, but it doesn't seem to be. Also, I've checked that the
replication is taking place and it's fine.

Any ideas?

Hello net_admin,

Remove them manual, no problem. Also you have to remove it manual from AD
sites and services.

Best regards

Hello Meinolf,

I always do that, both from DNS and ADSS. But it's annoying to do it to all
DNS zones everytime I demote a box.
I even dump the entire AD DB with LDIFDE and search throught it.

It would be nice to have a proper cleanup.

Cheers.

You are being thorough (which is a good thing) - but you should be able to
identify the relevant DNS records registered by a domain controller in the
forward lookup zones by examining content of the local
%windir%\system32\config\netlogon.dns file...

Hi
- You can do it manually or using dnscmd in a script, check at Script center
for samples of this.
- But this shouldn't be a thing that you do regularly, is it? Are you
constantly removing DCs from your domain?

I hope that the information above helps you.
Have a Nice day.
