From time to time you want to speed things up when deploying or upgrading schema or configuration of AD. If this is a case you can force to replicate all info between all domains controllers by specifiyng a command:

repadmin /syncall dest-domain-controller /APed

/syncall – all information

dest-domain-controller  – pretty obvious. If running on a DC, there’s no need to specify a destination DC.

/A(ll partitions)P(ush)e(nterprise-all sites)d(istinguished name)

Above method might be a good check if you suspect some replication delays/erros between DC’s.

Just to remember, you can check replication status by specifying the following command:

repadmin /showreps
