Moving FSMO Roles via Command line

 Listing all the FSMO roles at once via different ways -

Command 1- net dom query fsmo

Command 2 - Listing Domain Wide FSMO roles

Command 3 - Listing Forest wide FSMO roles

As per all above snaps, we can find out which DC's are holding different FSMO roles.

Our task would be to move Schema & Infrastructure master role from "DDC01" to another DC named "GDC01".

Below command will be used for movement.

Syntax 

Move-ADDirectoryServerOperationMasterRole -Identity "DestinationDC" -OperationMasterRole 'FSMO Roles separated by comma'

  We can then check again & this time we will see those two roles on another DC.

Syncing / Unsyncing an OU from Azure AD Connect

 Scenario-

I have an OU named "Dummy OU" containing 3 sub OU's. At present all 3 Sub OU's are syncing but as per requirements i have to Unsync  one of the Sub OU named "Dummy Groups".

Solution

First, we will open Azure AD Connect. Connect to Azure AD by providing 'Global Admin' Credentials of your tenant.

Connect to OnPrem AD

Next would be unselect "Dummy Groups" OU under Domain and OU filtering

We will then proceed & Click on Configure. Incase you don't want to initiate the syn right now, uncheck it.
