In real network, when operations master server fails due to hardware issues or some other problems, we need to move the operation master role to another domain controller as soon as possible. This move process is called seizing. Therefore, Seizing an operations master role means forcing an operations master role onto another domain controller. Before we seize operations master roles, we must permanently disconnect the domain controller that holds the operations master roles  from the network.

Here, all Operation Master Roles are on KTM-DC01-2K8 domain controller. In this scenario, currently this server is Offline due to hardware problems. So we get an error when we open Operations Masters roles on other domain controller KTM-DC02-2K8. To solve this problem, we have to seize Operations Masters roles and reassign it to KTM-DC02-2K8 domain controller as soon as possible.

Before KTM-DC01-2K8 become Offline, all Operations Masters Roles are in the KTM-DC01-2K8.

Use ntdsutil to perform this procedure:
1. Log on to KTM-DC02-2K8, working DC.

2. Open Command prompt, in the Run box, type cmd and then Click OK.

3. At the Command Prompt, type ntdsutil and press Enter.
