Sysvol/Netlogon not shared. trying Authoritative restore

Applies to Windows 2012

I have 4 DC, all single NIC, DNS setting should be correct (primary is self referencing, seoncdary others in a round robin).  All machines on the same subnet.

Only one machine (PDC) has a shared sysvol and netlogon folder.

Reading  suggests using adsiedit to do an authoritative restore.

However, I am missing the msdfrs-options parameter in the cy=sysvol subsrciption...

So what to do?

I will try the non authoritative procedure first and see if that works...

Note, dcdiag on the PDC work normally, where DCDIAG on all the other machines pass all tests except advertizing since the two shares are absent.
