SYSVOL and/or NETLOGON share not created after DCPROMO
Just promoted a machine as DC with DCPROMO and the SYSVOL or NETLOGON shares are not created?
No worries, this happens a lot. This can be fixed by setting the new domain controller as non-authoritative.
To get the domain controller to re-establish the shares properally and publish it under the domain namespace theres a trick to this which I will show you.
Navigate to the following registry key on the domain controller you just copied the SYSVOL to:
HKLM\SYSTEM\CurrentControlSet\Services\Ntfrs\Parameters\Backup/Restore\Process at Startup
Set the value of the BurFlags registry entry to D4.
D2, also known as a nonauthoritative mode restore
D4, also known as an authoritative mode restore
Restart the Ntfrs service (File Replication Service)
The DC will now automatically share the SYSVOL and republish it under the domain namespace.
