If Sysvol is missing then you will have lost all your policies and any login scripts.<br />
<br />
You can re-create the Default Domain Policy and Default Domain Controller Policy using the Dcgpofix.exe command. The rest will have to be manually re-created.<br />
<br />
Run NET VIEW \\DC-Server-Name to check if NETLOGON and SYSVOL appear.

<div>
Do you not have a backup of any Domain Controllers ?
</div>

Hi Peter<br />
<br />
SYSVOL folder on both servers are still there and so are the policies, but there is a problem with the GPOs syncing. I have DFSM installed on both server and under replication the domain system volume is missing. <a href="https://filedb.experts-exchange.com/incoming/2018/02_w07/1275045/DFSR05.JPG" target="_blank" title="DFSR05.JPG (21 KB)"><img alt="DFSR05.JPG" class="file-block lazyload" style="max-width: 405px;" data-src="https://filedb.experts-exchange.com/incoming/2018/02_w07/1275045/DFSR05.JPG" /></a>

<div>
there are backup of the domain controller, but the problem is that the backup don't go back far enough to fix the problem
</div>


<div>
First of all take a copy the folder, and a full backup of at least one DC, if they are VMs take an online checkpoint.<br />
<br />
I would have a look at the like &quot;D4&quot; for FRS&quot; section of this.<br />
