This article shows you an example analysis of the role of operating host occupied by Windows Server 2008. The content is concise and easy to understand, and it will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Case study:

Suppose there are only two DC in the current domain

Occupation of the operation host role is generally used for two DC when one of the DC is broken and cannot work, you need to transfer the operation host role to the other DC to continue to work.

Active Directory supports multi-host replication of directory data stores between all domain controllers in the domain, so all domain controllers in the domain are essentially equivalent. However, some changes are not suitable for use with multi-host replication, so for each such change, a domain controller called the "operation host" receives a request for such changes.

In each forest, there are at least five operations host roles assigned to one or more domain controllers. The forest-wide operations host role must appear only once in each forest. In each domain in the forest, the domain-wide operations host role must appear once in each domain.

The transfer operation host role is performed online with good security and can be used when upgrading hardware to transfer the DC on the older equipment to the new machine.

Occupies the operation host role to execute offline, has certain hidden trouble.

The following are the steps to take up the operation host:

It is recommended to back up the original system before operation.

First log in to the second DC.

Run cmd

Enter the command netdom query fsmo

View the current operation host information. You can see that the current operations host roles are all on another DC.

Let's start to occupy the role of the operation host.

Enter a command

> ntdsutil

: roles

: connection

: connect to server DC2.zhaoyun.com

: quit

After entering the following command

Then execute the command:

All the pop-up messages are selected as

Up to now, all five operating hosts have been occupied.

Complete the transfer of the operation host.

Enter the command after exiting

Netdom query fsmo checks whether the role of the current operation host has been transferred successfully.

You can now see that all the operations host roles have been successfully transferred to DC2.

At this point, all operating hosts have been successfully occupied. The extra DC has become the primary DC.

The above is an example analysis of Windows Server 2008 occupying the role of the operator. Have you learned any knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
