After countless hours of scouring the web, the only thing I could do to get rid of these errors was
**DO NOT DO THIS WITHOUT CONSULTING THE NETWORK ADMINISTRATOR**
cd to “\program files\gpmc\scripts” and run “Cscript
GrantPermissionOnAllGPOs.wsf “Enterprise Domain Controllers”
/Permission:Read /Domain:yourdomain.local”.
**This issue can be avoided during upgrade by using “adprep
/domainprep /gpprep” during the domainprep-stage of the domain
upgrade.**
