Suppose I am creating new OU to Secondary (Backup DC) Server

Created OU Structure and user to Backup DC – Secondary DC

 

So, it also replicating in Primary DC Server

 

 

 

 

 

If there are any problems on Primary server how to retain Secondary Backup Server

 

Primary Server FSMO Roles

Netdom query fsmo

 

 

Secondary server will also getting same roles but secondary server not having complete authority like Primary DC

If Primary Server having issues need to seize the fsmo roles after that Backup DC will retain complete authority

So, here I used to power off Primary Server

Primary DC is not active

 

 

Now type in PowerShell

But still, I will get all 5 FSMO roles

 

 

In secondary server I am getting all 5 Roles

Type

In Backup DC

Ntdsutil

Just type only roles and press enter

 

 

 

 

 

Type connections

Now need to connect to in backup Domain Controller like---

 

Connect to server bdc.vre.local

 

 

Now quit from connection press type q and enter

 

Here we need to seize all fsmo roles from primary server

Primary server is not running but fsmo roles with primary server need to seize the roles and allocate to secondary server

netdom query fsmo

 

fsmo maintenance: Seize infrastructure master

And press

Yes

 

 

fsmo maintenance: Seize naming master

 

fsmo maintenance:  Seize PDC

 

Seize RID master

 

 

Seize schema master

 

Now type q
