Active Directory: Force Replication Of All Domain Controllers On All ...

Active Directory Domain Services uses pull replication to replicate Active Directory Partitions. This means that the Domain Controller on which replication is started receives the data from the source Domain Controller. It’s like a one way ticket.

If you want to replicate all Domain Controllers, then you have to start replication on each of them separately. This may take a while. To save time, I am going to show you a PowerShell One-Liner to force replication on all Domain Controllers of all Active Directory Sites. Let’s take a look at this One-Liner now.

Force Replication of all Domain Controllers on all Sites

Suppose, you have one Domain with multiple sites. (One Forest and one Forest Root Domain).

Log on to one of your Domain Controllers. Start Windows PowerShell with administrative privileges. The domain name and the domain partition don’t need to be specified. They will be filled automatically by Get-ADDomain. 😉

function Replicate-AllDomainController { (Get-ADDomainController -Filter *).Name | Foreach-Object {repadmin /syncall $_ (Get-ADDomain).DistinguishedName /e /A | Out-Null}; Start-Sleep 10; Get-ADReplicationPartnerMetadata -Target "$env:userdnsdomain" -Scope Domain | Select-Object Server, LastReplicationSuccess }

Once completed, you get a nice overview with the computer names of the Domain Controllers and the time of the Last Replication Success.

That’s it.

Have fun replicating your DC’s! More about repadmin here:
