Hello satyamahapatra1,
Thank you for posting in Microsoft Community forum.
Please check AD replication in the forest by running commands below on the PDC.
repadmin /showrepl >C:\rep1.txt
repadmin /replsum >C:\rep2.txt
repadmin /showrepl * /csv >c:\repsum.csv
Check the results of these commands.
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
