Name OS FSMO Holder
MCLS-DC03 2012 Yes
I am trying to migrate my Domain Controllers from 2008 to 2012 Standard Edition. My goal is to demote DC01 and DC02 so I can remove them from the network. All servers point to DC03 and DC04 for DNS. When I run dcpromo, it errors out with the message in the attached Picture called "AD Error". I have followed the instructions from this site to try and resolve this,
but it does not resolve it because I can not make the change it refers to. The first issue I have is that the website and all other sites that I have found refers to when the demotion fails and its for DC=ForestDNSZones. My error is for DC=DomainDNS Zones. If you follow the websites instructions it wants you to open ADSI Edit and connect to DC=DomainDNSZones......etc
. When I do this, I am on the FSMO role Master and get the following error in the attached picture called ASDIEdit and will not allow me to change the name to DC03 which is the new FSMO Master. The highlighted section is referencing and old server called MCLS-SVR01 that has not been in service for years. I have also attached a picture of a netdom query for FSMO. Thank you in advance.
