Modify the Active Directory domain controller computer name

In the previous article about modifying the IP address of Active Directory, as well as the place to be verified after the modification, today we mainly introduce the places to be verified after modifying the computer name of the DC server, as well as considerations.

1. The machine used in this space is still "sh-dc-01" and is ready to be renamed "BJ-DC-01"

2. Use the following command to verify the fully qualified domain name of the current DC server, the FQDN

650) this.width=650; "height=" 266 "title=" clip_image003 "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none, "alt=" clip_image003 "src=" http://s3.51cto.com/wyfs02/ M00/6e/4c/wkiom1v4m_ysmurdaafw2o3u50s311.jpg "border=" 0 "/>

3. Add a new FQDN name for the DC server. The new service subject name (SPN) is registered in the Active Directory database and a new computer name resource record (SRV record) is registered in the DNS server.

650) this.width=650; "height=" 126 "title=" clip_image005 "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none, "alt=" clip_image005 "src=" http://s3.51cto.com/wyfs02/ M01/6e/4c/wkiom1v4m_yz9yg9aadakhclgtk987.jpg "border=" 0 "/>

4, execute the following command to view the current DC server all the available FQDN names, you will find in addition to the original sh-dc-01.contoso.com, a new bj-dc-01.contoso.com record

650) this.width=650; "height=" "title=" clip_image006 "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none, "alt=" clip_image006 "src=" http://s3.51cto.com/wyfs02/ M02/6e/4c/wkiom1v4m_zrmghgaaetkjidpqo718.jpg "border=" 0 "/>

5. Use the following command to set the new FQDN record in the Active Directory database to online mode

650) this.width=650; "height=" 186 "title=" clip_image008 "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none, "alt=" clip_image008 "src=" http://s3.51cto.com/wyfs02/ M00/6e/4c/wkiom1v4m_zznbz0aafc1kt27kq570.jpg "border=" 0 "/>

6, according to the prompt, need to restart the DC server, so here to perform a reboot DC server operation

7. After the DC server restart is complete, execute the following command to delete the sh-dc-01.contoso.com

650) this.width=650; "height=" 207 "title=" clip_image010 "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none, "alt=" clip_image010 "src=" http://s3.51cto.com/wyfs02/ M01/6e/4c/wkiom1v4m_2hjet3aaeezm8rzhg840.jpg "border=" 0 "/>

8. Use the following command to view the FQDN of the current DC server. This has been successfully modified to bj-dc-01.contoso.com

650) this.width=650, "height=" "title=" clip_image011 "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none, "alt=" clip_image011 "src=" http://s3.51cto.com/wyfs02/ M02/6e/4c/wkiom1v4m_3rxgmhaaemap4fkdc715.jpg "border=" 0 "/>

9, click Server Manager, click Configure this local server, view the current DC server new computer name

650) this.width=650; "height=" 401 "title=" clip_image013 "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none, "alt=" clip_image013 "src=" http://s3.51cto.com/wyfs02/ M00/6e/48/wkiol1v4naoygbg_aaff2svdcsi315.jpg "border=" 0 "/>

10, here, the DC server computer name has been modified to complete, but in order to ensure that the DC server is available, you also need to verify that the following settings have been successfully modified

11. Open the DNS Server Management console to see if bj-dc-01.contoso.com is added to DNS

650) this.width=650; "height=" 373 "title=" clip_image015 "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none, "alt=" clip_image015 "src=" http://s3.51cto.com/wyfs02/ M00/6e/4c/wkiom1v4m_3qgp3haagof4qijba306.jpg "border=" 0 "/>

12, through you will find that the original FQDN still exists in DNS, because the DNS does not delete the record itself, so you need to manually delete the sh-dc-01.contoso.com

650) this.width=650; "height=" 204 "title=" clip_image017 "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none, "alt=" clip_image017 "src=" http://s3.51cto.com/wyfs02/ M01/6e/4c/wkiom1v4m_3hglm6aaczztgkjbq915.jpg "border=" 0 "/>

13. Expand "contoso.com", "_sites", "Default-first-site-name" _tcp "Verify that the SRV record is updated to bj-dc-01.contoso.com new FQDN record

650) this.width=650; "height=" 225 "title=" clip_image019 "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none, "alt=" clip_image019 "src=" http://s3.51cto.com/wyfs02/ M02/6e/48/wkiol1v4naptq2h8aad3i89klte583.jpg "border=" 0 "/>

14, the above verification is correct, you also need to verify the five major roles of the DC server (operations master), using the following command to verify

650) this.width=650; "height=" 236 "title=" clip_image021 "style=" margin:0px;border:0px;padding-top:0px; Padding-right:0px;padding-left:0px;background-image:none, "alt=" clip_image021 "src=" http://s3.51cto.com/wyfs02/ M00/6e/48/wkiol1v4nassnoe9aaf3levrzr8642.jpg "border=" 0 "/>

The computer name of the DC server for Active Directory has been modified.

PS: Never modify the computer name directly in the computer properties. This causes the computer's properties to be inconsistent with the Active Directory database, resulting in the inability to use the resources within the domain, and frequently joining the computer to the domain.

650) this.width=650; "height=" 993 "title=" clip_image023 "style=" border:0px;padding-top:0px;padding-right:0px; Padding-left:0px;background-image:none, "alt=" clip_image023 "src=" http://s3.51cto.com/wyfs02/M01/6E/48/ Wkiol1v4nasyvdx8aamspnnqtc4053.jpg "border=" 0 "/>

The reasons for writing these two articles are also because many friends recently changed the IP address and computer name of the DC server according to the usual method because they were not clear about the importance of the DC server. I hope to use these two posts as a reference for friends in need.
