"Failed to Open the Group Policy Object" error

"Failed to Open the Group Policy Object" error could indicate an Active Directory communications issue. Site expert Kevin Beaver gives advice on how to solve this AD problem.

When I open Domain Control Security Policy, I get the error "Failed to open the Group Policy Object. You may not have appropriate rights." When I run GPOTool, I get the following error:
