You want to determine if replication is succeeding.
The following two commands
help identify problems with replication on a source domain
> dcdiag /test:replications
> repadmin /showrepl /errorsonly
For a more detailed report, you can use the Replication Monitor
(replmon.exe). The Generate Status Report option
will produce a lengthy report of site topology, replication
information, and provide details on any errors encountered. The
Directory Service event log can also be an invaluable source of
replication and KCC problems.
