I have 2 old domain controllers that no longer exist showing in the "Manage Authorized Servers" in "DHCP", when I try to unauthorize them I get an error that says "There is no such object on the server."

Try right click on ADSI Edit and click connect to. In connection settings, connection point, select or type a Distinguished Name or Naming Context. Enter CN=NetServices,CN=Services,CN=Configuration,DC=Your Domain,DC=com then click ok.
Expand the default naming context, highlight the path in the left pane, and you should see CN=DhcpRoot on the right.
Double click it, and then check for and edit the dhcpServers attribute to reflect the correct computers. The restart DHCP service.

You can perform some cleanup to remove the non-existent domain controllers.

Hi,
Welcome to ask here!
It is suggested to confirm if there are any old reference existing in the domain.
You can check this by:
AUDC domain trollers OU
AD Site and services
AD DNS Records
Or when you run dcdiag and repadmin.
Then try to do a metadata cleanup for the old DCs from other good ones.

Best Regards,
Just checking if there's any progress or updates?

I can't find any reference to the old Domain Controllers in AUDC Domain Controllers OU, AD Sites and Services or AD DNS Records. The DCPROMO and deleting was done when the new domain controllers were installed but for some reason the old ones still show up in that 1 spot.
When I try to connect in ADSI Edit it comes up with the error "Operation failed. Error code; 0x202b. A referral was returned from the server. 0000202B: RefErr: DSID-0310082F, data 0, 1 access point ref 1: 'your domain.com'
When you open? or when you type in the Naming Context? If the latter then there may be a typo in the path
That's what I was doing wrong, I wasn't putting our domain name in. I'm sorry. Okay now a see CN=DhcpRoot, under that I see 3 CN=domain controllers. 1 of them is the old domain controller that no longer exists, 2 of them are the current domain controllers.
