Recently I faced an issue with one of our clients where he was unable to  run the DCPromo to demote the server , he was getting the below error.

The server operating system was Windows 2008 R2.

01-Floating single-master operation roles

After some research I found out that the reason is that the fsMORoleOwner  attribute was pointing to an incorrect entry ,it may contain an entry such as “0ADEL:123456f8-1238-1233-1230-123456361b8b”  But the actual FSMO role owner is   dc1.test.local.

I was trying to change the attribute via ADSI Edit  on the server which I need to demote  , But again I was faced with the below error.


So  if anybody faces a similar incident  , they should do the below steps. by log in to the current domain controller which was holding the schema master role

* Identify the current FSMO Role Owner by

netdom /query fsmo

1 Login to the current owner  ,  and open the ADSI Edit

2 Connect to the DC=ForestDnsZones,DC=test,DC=lab

3 Right click on  CN=Infrastructure  go to Properties

4 On CN=Infrastructure Properties   click on fsMORoleOwner attribute and click on edit  you will find an incorrect entry  as below fsmo_Wrong_entry

5 Clear the text and enter the below text.

CN=NTDS Settings,CN=dc,CN=Servers,CN=HeadOffice,CN=Sites,CN=Configuration,DC=test,DC=local.

After the above steps   repeat the step2  to connect it to the  DC=DomainDnsZones,DC=test,DC=lab and repeat the steps 3,4 & 5


Voila Press OK and close the ADSI Edit  and now login to  the server where you want  to demote and run the DCPromo command and now you will be able to complete the wizard without any error
