How to Force Active Directory Replication

If you make a changes on DC01 and you want to replicate those to other DCs instantly, run command repadmin /syncall /APeD on DC01.

A = All Partitions
P = Push
e = Enterprise (Cross Site)
D = Identify servers by distinguished names

If DC01 is out of sync, you should run command repadmin /syncall /AeD on DC01.
This will do a pull replication, which means it will pull updates from DC02 to DC01.
