Frequently Asked Questions
1
What recovery step resolved the reported environment after uninstalling the update did not help?
Resetting the domain controller's secure channel to itself resolved the reported authentication and DNS administration access issues. Rolling back the update alone did not resolve the issue in that case.
2
Which services or user workflows were affected in the reported incident?
Users were prompted for credentials when accessing mapped drives and folder redirection, and no credentials were accepted. DNS name resolution and domain services continued running, but opening the DNS console and running DNS PowerShell commands returned Access Denied.
3
Did the reported issue prevent all domain administrator access?
No. The reporter could still log on locally as a Domain Admin, despite being unable to administer DNS through the console or DNS PowerShell commands.
