Hello RAAJCO SPINNERS PRIVATE LIMITED KARUR,
Thank you for posting in Microsoft Community forum.
How many DCs are there in your domain except this the Windows Server 2012 R2 domain controller you restored?
How did you restore the Windows Server 2012 R2 domain controller?
You can check the DC health of the Windows Server 2012 R2 domain controller you restored, run Dcdiag /v on this DC.
You can check AD replication if you have more than one DC in the domain, run commands below on PDCs.
repadmin /showrepl >C:\rep1.txt
repadmin /replsum >C:\rep2.txt
repadmin /showrepl * /csv >c:\repsum.csv
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
Daisy Zhou
