Dear Microsoft Support Team,
I hope this message finds you well. We are reaching out to report an issue that has arisen after the installation of the KB5028166 update on our Windows 10 computers in July 2023.
Since the update, all computers that are not joined to the Samba4 domain are encountering an error message, specifically: "The trust relationship between this workstation and domain failed," when attempting to access the shared computer that has received this patch.
We have already tried various online solutions to remove the KB5028166 update, such as using PowerShell or command prompt, but none of them have been successful.
We are interested in knowing if Microsoft has plans to release a fix or update to rectify this issue. Your prompt response and assistance in resolving this matter would be highly appreciated.
Thank you for your attention to this concern.
Warm regards,
Mr. Yii
