GUI folders missing in \\sysvol\domain\policies - Andrei

Long short story.
One domain  -  1 DC
1 month ago created the 2nd DC -> 1 domain 2 DCs
One of the DC become hw unstable (the 1st dc in the domain - old machine)
and I had to demote it using /forcedemote switch. Cleaned up AD using
ntdsutil.
status: 1 domain - 1 DC
1 week ago promoted another DC -> 1 domain - 2 DCs
Immediately after I found out that sysvol folder was missing. I've recreated
the sysvol folder and subfolders using the D2 and D4 reg values.
Yesterday after I checked the sysvol folder and I noticed that under
\\sysvol\domain\policies there were no folders (GUI with brackets). I checked
the advanced tab in AD\users and computers\system\default domain policy also
nothing there but tones of event id :1030 source:usernv.
log for possible messages previously logged by the policy engine that
describes the reason for this."
GPMC cannot find path in group policy objects for DC policy, domain policy
and  sp users logon deny.
At this point I do have only a copy of the sysvol folder that was taken 1
month ago from the 1st DC that has been forcedemoted. The GUI folders all
three of them are there. They seem to be intact.
1. Is there any possibility to restore those policies having those folders
from backup?
2. If not what would be the consequences if I use dcgpofix?
Thank you very much in advance.

Andrei
