This Group Policy object (GPO) is inaccessible because you do not have the read-level permission on it

If you lost permissions to a GPO, obviously you cannot edit the GPO in Group Policy Management Console (GPMC). You would get this error: This Group Policy object (GPO) is inaccessible because you do not have the read-level permission on it.

Don’t you worry. There is an easy fix as long as you are a domain admin.

• Open ADSIEdit.msc console
• Right click on ADSI Edit and select “Connect to…”. Choose “Default Naming Context” and click OK.

• Expland to ADSI Edit >>> Default Naming Context (domain.com) >>> DC=company,DC=com >>> System >>> Policies

• Find the GUID of the GPO you lost access in Group Policy Management Console. Select the GUID of the Policy under CN=Polices OU.
• Right click on Policy and choose Properties.
• Select Security Tab and Click Advanced Button.
• Take ownership of the policy by changing the owner to yourself (or better to Domain Admins). Close the properites dialog box.
• Right click on the Policy and open Properties again.
• Go to Security Tab. I would suggest to add permissions by copying the default permissions from other policy.
• You may close the ADSI Edit console.

That’s all. After permissioning try accessing the GPO in GPMC.
