Error trying to open Group policy Management Editor in Server 2008 R2

make sure you have enough permissions on SYSVOL folder.

You must have read or write access to the gplink and gpoptions propeties on the gpo.

What account are you using to try to edit the gpo?

By default, domain admins have this right.

make sure you have read and write access to the gpo you are trying to modify.

http://technet.microsoft.com/en-us/library/cc776858(WS.10).aspx

The permissions are fine. I have been in and out of this policy many times as I have been creating it. I am logged onto the server as an administrator. I just received this error all of a sudden.

Not sure what you mean. I get this error trying to open the policy.

Is it for this policy only?

Yes

Is this a new domain controller? Was this GPO created on this DC?

It is a new domain controller, a secondary server in an existing domain. The GPO was created on this domain controller by myself. I was in and out of this policy dozens of times making changes before this error occurred.

Policy is still in SYSVOl folder?

yes

Have you tried opening from another station?

Yes, no luck. I am assuming the policy is just corrupt at this point and that I will have to replace.

Yes, that is what I am assuming. Thanks for your assistance along the way.

thanks
