Server - DCPromo out fails unable to determine the ownership of floating single-master operation roles.

We faced this error during dcdemote

DCPromo out fails with: The directory service is missing mandatory configuration information, and is unable to determine the ownership of floating single-master operation roles.

Following commad was correct:

netdom query fsmo

But on all dc there was old informations that pointed to old PDC DC that no longer exist:

dsquery * CN=Infrastructure,DC=ForestDnsZones,DC=sevescorp,DC=com -attr fSMORoleOwner

output

CN=NTDS Settings\0ADEL:123412345-1234-1234-1234-123123123123,CN=XXXX-AD\0ADEL:123412345-1234-1234-1234-123123123123,CN=Servers,CN=xxxx,CN=Sites,CN=Configuration,DC=xxxxxxxx,DC=com

then we opened ADSIEdit.msc and connected to: 

CN=Infrastructure,DC=ForestDnsZones,DC=domain,DC=int



and we changed these information to correct one:



You must execute this activities on schema master DC

Same procedure must be replicated on 

CN=NTDS Settings,CN=,CN=Servers,CN=,CN=Sites, CN=Configuration,DC=domain,DC=local

With ADSI edit using this article on point 3.:

To get correct string you need to view point 1. of precedent article and mainly going here:

we changed this information and thereafter they was correctely replicated and dcdemote was working fine
