What is the cause of error message "The Group Policy Client Service failed the sign-in. Access is denied" ?

Question

Hello, my computer is having an issue where the note keeps coming up when I log onto my account. "The Group Policy Client Service failed the sign-in. Access is denied?”

The last time I had access to this account was to download some school files and a physics application called ‘Tracker for Video analysis and modelling tool” I also had my personal OneNote open.

I have already tried resolving the issue by

• Restarting the computer
• Check for Malware/Viruses using a antivirus.
• Restarting Group Policy Client Service
• Check the settings if Group Policy Client were configured right.

Thanks in advance,

RB

Hello RB,

Thank you for posting in Q&A forum.

This error usually means that the Group Policy Client service, which handles user settings and permissions, didn’t start correctly during login. It often occurs because of a damaged user profile or problems with Group Policy Objects (GPOs) being set up incorrectly or being damaged.

It can also be caused by communication issues with domain controllers, which are needed for Group Policy functions in network environments.

You can try the possible method in this similar thread below.

5.If this user profile is roaming profile, you can try to rename the users roaming ntuser.dat file.

For example, here is a ntuser.dat file in local path of the user TestB.

Please note:

1.Always back the registry before you make changes on registry.
2.Always back up important data in user profile before you delete/remove user profile folder.
