Here is a handy tip on how to force replication of Windows 2008 Domain Controllers using Repadmin. There is a GUI and a command line.
From time to time its necessary to kick off AD replication to speed up a task you may be doing, or just a good too to check the status of replication between DC’s.
Below is a command to replicate from a specified DC to all other DC’s.
Repadmin /syncall DC_name /APed
By running a repadmin /syncall with the /A(ll partitions) P(ush) e(nterprise, cross sites) d(istinguished names) parameters, you have duplicated exactly what Replmon used to do in Windows 2003, except that you did it in one step, not many.And with the benefit of seeing immediate results on how the operations are proceeding.
If I am running it on the DC itself, I don’t even have to specify the server name.
