AGPM 4.0: error message and Archive not found

[ebenda]

I have been unable to get AGPM 4.0 to work. When I go to Change Control I get the following error message: "Failed to read production GPO permissions for this domain. The following error occurred: Microsoft.AGPM.NativeErrorException (8007202B)"

After clicking OK, I get "Archive not found" under Group Policy objects on the Controlled tab. The Contents tab is then frozen until I click another tab on that level. After doing that and coming back to the Uncontrolled tab, all GPOs are listed. When I try to control one of these GPOs, the process fails.

The AGPM server is 2008 R2, the client is Win7. I have checked all permissions the agpm service needs that I am aware of. Making the agpm service account a domain admin doesn't help, it produces same result. I've also uninstalled/installed with same result. Server and client logs are attached, nothing in them has been any help to me.

AGPM needs to contact the root of the forest even if you are only managing GPOs in a child domain. Possible reasons include security filtering or permissions on GPOs referencing groups or users in another domain. GPOs linked to sites is another possible reason. MS was never able to tell me exactly what AGPM was looking for in the our forest root, but the issue occurred simply because our forest root was unavailable at the time. I was not aware of this. We now have a forest root DC locally.
