The infrastructure and usage of Active Directory (AD)

In the process of using AD Domain Services, we will encounter the unexpected situation of domain controller failure, in order to ensure that in the face of unexpected situation, the fastest solution to the problem, you need to use the AD domain service backup and restore, today will bring you a few cases, so that we can further understand the AD Domain Services.

Impersonation environment: Server crashes, restore with backup system state.

Prepare: 1) Reinstall the system server. (because the emulation server crashes, so to re-install the system to the server, this is not described in detail here.) ）

2) The past backup needs to be imported into the server. (Note: No matter what method to import the backup, do not put in the system disk!!) ）

Step one: To reinstall the system server, rename, (the name before the system crashes), change the IP address (IP before the system crashes), turn off the firewall, turn on remote.

These steps, I believe we all understand, here is not introduced, we directly into the topic.

Step two: On the new server, install active Directory Domain Services, Windows Server Backup

Step three: After the installation is complete, elevate the server to a domain controller.

(Note: The domain name does not need to be exactly the same as the original domain, and is intended to generate the directory service Recovery model.) ）

The original domain name is zc.com, here we use another domain name zxc.com to do domain name.

The reason for this error is that the preferred NDS is not configured, if this error occurs when raising a domain controller, please check the preferred DNS designation.

Note: Because we are in a virtual environment, these two warnings can be ignored.

Click Install

Step Five: Restart your computer to check if the restore was successful.

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; border-bottom-width:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/6B/7B/wKiom1UuZMTgi_XMAAB_ Mesjtgq273.jpg "width=" 644 "height=" 325 "/>

Check: 1) Check whether the user is restoring

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; border-bottom-width:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M01/6B/76/wKioL1UuZhvi7ekMAAD-uPF_ 1ru671.jpg "width=" 644 "height=" 364 "/>
2) Check that the DNS records are healthy

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; border-bottom-width:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/6B/76/wKioL1UuZhyAkS_ 5aaelabsroiw522.jpg "width=" 644 "height=" 364 "/>
3) Check the ad management tools and shared folders

650) this.width=650; "title=" image "style=" border-left-0px; border-right-width:0px; border-bottom-width:0px; border-top-width:0px "border=" 0 "alt=" image "src=" http://s3.51cto.com/wyfs02/M00/6B/7B/ Wkiom1uuzmqryoo9aadau4rbr6m993.jpg "width=" 644 "height=" 364 "/>

If none of the above checks go wrong, it proves that the experiment was successful.
