Compete for the role of operation master
In the environment of multi-domain controller, the primary domain controller is suddenly damaged due to hardware failure, and there is no backup in advance, how to make the extra domain controller take over its work and make the Active Directory run normally, and how to restore the damaged primary domain controller after the hardware is repaired.
Treatment method:
Clear the primary domain controller object from AD
Perform five capturing FMSO operations through the ntdsutil.exe tool on additional domain controllers
Set the extra domain controller to GC (global catalog)
Reinstall and restore damaged primary domain controller
View the commands of the five roles: netdom query fsmo
Delete useless primary domain control:
1. Domain Super Admin account (administrator) must be used
two。 Administrative tools-- active directory sites and services-- find the bad domain control server-- delete all content in NTDS Settings-- delete server sites
3. Open active Directory and computer-- domain controllers-- removes the broken primary domain control computer.
Use Ntdsutil to compete for roles
Use the command line tool ntdsutil on essBDC to compete for RID master. Disconnect the network connection from the essDC. The simulated ess failed.
To compete for the operation master role using the ntdsutil command, perform the following steps:
1. Type cmd in the run text box and press enter.
two。 At the command prompt, type ntdsutil.
3. At the ntdsutil prompt, type roles.
4. At the fsmo maintenance prompt, type connections.
5. At the server connections prompt, type connect to server essBDC.ess.com.
6. At the server connections prompt, type quit.
7. At the fsmo maintenance prompt, enter?, enter, and you can see the commands available at that prompt.
8. At the fsmo maintenance prompt, type one of the following commands to compete for the appropriate operational master:
Seize RID master
Seize PDC
Seize schema master
Seize infrastructure master
Seize naming master
Please note that there are two methods: Seize and Transfer. If the owner of the original FSMO role is offline, use Seize, and if you are online, use Transfer. Here, since the primary domain E-copa is offline, use "Seize"
