Could also be a permissions issue on the folders/locations that are referenced.

Did you ensure the Group Policy client was enabled and started on the workstation you are testing on?
Yes I did

I resolve the above and now I am getting the below error:
The following warnings were encountered during computer policy processing: Windows failed to apply the Scripts settings. Scripts settings might have its own log file. Please click on the "More information" link. Windows failed to apply the Internet Explorer Zonemapping settings. Internet Explorer Zonemapping settings might have its own log file. Please click on the "More information" link. User Policy update has completed successfully. The following warnings were encountered during user policy processing: The Group Policy Client Side Extension Folder Redirection was unable to apply one or more settings because the changes must be processed before system startup or user logon. The system will wait for Group Policy processing to finish completely before the next startup or logon for this user, and this may result in slow startup and boot performance. For more detailed information, review the event log or run GPRESULT /H GPReport.html from the command line to access information about Group Policy results. Certain user policies are enabled that can only run during logon. OK to log off? (Y/N) -

@wirestyle22 Problems with all of them? or just the one(s) that was/were hit with Ransomware?

Everything has the same error including workstations when you

This sounds like the AD Servers were restored from a backup and got out of sync... Could that be the case?

Yeah, it does. I am pretty sure that if you have an issue that you need to restore AD, you would bring down all DCs and restore a single DC, then add new DCs. But, I am thinking this would be better to do a completely new AD environment. Too many ghosts.

Nuke and pave is always a good answer... but jeez... Why do you need so many DCs to start with?
Our AD infrastructure here has nearly 40k people in it and we only have 6.

We ask that question every day

We didn't restore the DC's fully, just sysvol. Once we stopped the spread we spun up a new DC and took FSMO roles. Then on the weekend we built all new domain controllers.

Wait - who's making the decision? Is someone not in your department acting as IT?

Yes and no. Someone in IT long ago made this decision to put DC's in every office, which is not required. That became policy. So it's being enforced by people who aren't IT, but it was decided by former IT.
