Group Policy Best Practices Analyzer

I am getting a important error while running Group Policy Best Practices Analyzer. I think this is not appropriate. I was expecting to get clean result for this, but at the end it provided a critical error. There is a problem with permission and other issue. The DC looks to be working fine. But somehow the problem lies with incorrect permission. What should I do to fix this problem. Is there any automated way to fix the problem.

You will have to check back everything to find out where the actual problem lies. What I know about this the Enterprise DC has read permission for the GPO. And later on it authenticate the users and apply the same permission. I do not think there might be any problem with the default configuration. But somehow you will need to apply the permission.
