Replmon.exe not included in Windows Server 2008/2008 R2

A lot of administrators are used to check their Active Directory replication status using replmon.exe which is a part of the Windows Server 2003 Support tools.
Today I stumbled across the need to use replmon.exe on a domain controller running Windows Server 2008, and was unable to find it.

It turns out that that this utility is not included in Windows Server 2008/2008 R2.

According to a comment from a team member from the Microsoft Directory Services Team, this is the explanation:

“Unfortunately, replmon did not survive the transition to Win2008. It was actually developed by MS support, not the product group (along with many other support tools/resource kit tools), and without an actual owner to service the tool years later, it was a casualty. I don’t see why it wouldn’t work on 2008 though…”

I wouldnt recommend using unsupported tools on Windows Server 2008/2008 R2, so the advice would be to either use repadmin.exe on 2008/2008 R2, or to use replmon.exe from a Windows Server 2003 server.

You can find the command reference for repadmin.exe in Windows Server 2008/2008 R2 here.

A few examples:

repadmin.exe /showrepl shows the replication-status for the domain controller the tool are being run from.

repadmin.exe /showrepl servername shows the replication-status for the domain controller with the provided servername,

repadmin.exe /queue shows the replication-queue for the domain controller the tool are being run from.

repadmin.exe /queue servername shows the replication-queue for the domain controller with the provided servername,

repadmin.exe /replsummary shows a brief summary of the replication status.

I also checked if there are any PowerShell cmdlets for checking replication status in Windows Server 2008 R2, but its not. Hopefully this will be implemented some time in the future.

PS: I did test installing the Windows Server 2003 Support tools on a Windows Server 2008 domain controller in a lab environment, and it does work.
