Hello all,
I am receiving a strange error message that I have never seen before in Group Policy. I am attempting to edit a GPO and I receive the following message:
"Failed to open the Group Policy Object. You might not have the appropriate rights."
"Details: The volume for a file has been externally altered so that the opened file is no longer valid."
I have looked online and have found very little about this message. Most of the things I come across relate to the local group policy, but my issue is occurring in the GPMC on a domain controller.
I have three domain controllers - Server 2008 R2, Server 2012 Standard, and Server 2016 Standard. I can edit this GPO on my Server 2008 R2 domain controller, but receive the error message on the other two.
I have tried this solution from my research, but it seemed to cause more problems than it fixed and didn't remedy the original issue:
- Get GPO GUID: from Group Policy Management Console (GPMC) –> choose GPO –> from right pane go to Details tab –> go to Unique ID field.
- Open the path: C:\Windows\SYSVOL\sysvol\<Domain>\Policies\<GPO GUID>\User
- Delete “registry.pol” file.
Has anyone see this before?
Thank you!
