Hello @Courtenay ,
Thank you for posting here.
After my view, I can see "Active Directory Web Services---This service provides a Web Service interface to instances of the directory service (AD DS and AD LDS) that are running locally on this server. If this service is stopped or disabled, client applications, such as Active Directory PowerShell, will not be able to access or manage any directory service instances that are running locally on this server."
1.Based on the description, do you mean the ADWS service on one Domain Controller can not be started?
2.If so, if you try to start ADWS service on this Domain Controller, what error message do you receive? Please provide the screenshot if possible.
3.After we try to start ADWS service on this Domain Controller (maybe the service can not be started), please check if there is any event logged in Event Viewer as below?
Should you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
