Do you know repadmin is the best tool for Active directory troubleshooting, editing or modifying but few knows there is something called repadmin /experthelp which shows you expert level cmd & it should be used with caution to modify any change in AD.
You might have used basic switches with repadmin like /showreps /showobjmeta /replsummary etc, but it has more to offer with expert cmd.
You know AD replication are based on per attribute basis, so if i want to see the all the attribute replicated with other dc, you can use repadmin /showobjmeta (cn=abc,ou=ouname,dc=corp,dc=cotoso,dc=com),it will show all the attribute replicated with the date, USN no & best thing is in order.
I remember the situation, where i wanted to track which DC has performed the password change & i used repadmin /showsobjmeta cmd & it gave me the complete listing.
