Repadmin /replicate command to trigger immediate replication
Repadmin /replicate:
Monitoring replication is vital part of managing your Active Directory network because many AD issues can be prevented by monitoring replication activity on your network. Windows Server 2008 provides a number of tools that allow problem discovery, diagnosis and resolution. In addition to the directory sere event log available in the Event Viewer, Windows Server 2008 provides several additional monitoring tools that are installed when you add the AD Domain Services role to a 2008 server. The tool discussed here formerly part of the Support Tools available on the Windows Server 2003 CD, but are now supported natively within the Windows Server 2008 operating system.

Repadmin:
Repadmin is command-line tool used for the following:
-Triggers the immediate replication of the specified directory partition to a destination domain controller from a source domain controller.
-To view the replication topology from the perspective of each domain controller. This aids in understanding how information is transferred, ultimately assisting in the isolation of replication problems.
-To manually create a replication topology if site link bridging is disabled because the network is not fully routed.
-To force replication between domain controllers when you need updates to occur immediately without waiting for the next replication cycle.
-To view the replication metadata, which is the combination of the actual data and the up-t-date vector r USN information. This is helpful in determining the most up-to-date information prior t seizing an operations master role.

The replicate command tests replication success after you remove suspected fault conditions without waiting for the replication schedule to open.
You can refer to the source or destination domain controller in any of the following ways:
By its single-label host name
By its fully qualified host name
By the globally unique identifier (GUID) that is assigned to the NTDS Settings object for the domain controller. You can obtain the GUID for the directory system agent (DSA) object from the header of the output of the following command:
repadmin /showrepl <name of domain controller>
Case-1.
Following example replicates the contoso naming context from source-dc1 to dest-dc2
Suppose Domain is contoso.com below is example...
repadmin /replicate dest-dc1 source-dc2 dc=contoso,dc=com
Example : repadmin /replicate dc1 dc2 dc=contoso,dc=com
Case-2,
Suppose your domain is ad.microsoft.com
dc1 in chicago site and dc2 in newyork site. then command would be
repadmin /replicate dc1 dc2 dc=microsoft,dc=com
If your getting any active directory partition related replication error then you should provide after dc2..
Case:3
Suppose If your getting some replication errors between two dcs resides in different sites and you knew that some partition not replicated then follow the below example command lines.
Suppose your domain is ad.microsoft.com and partition name are
Domain----------> Dc=ad,Dc=microsoft,Dc=com
Configuration----> CN=configuration,DC=ad,DC=microsoft,DC=com
schema----------> CN=schema,CN=cofiguration,DC=ad,Dc=microsoft,DC=com
dc1 in Chicago site and dc2 in new york site. then command would be
repadmin /replicate dc1 dc2 dc=microsoft,dc=com this command for replicate between two DCs and two sites ----command should be successful.
repadmin /replicate dc1 dc2 dc=ad,dc=microsoft,dc=com this command is for replicate domain partition between two DCs and dcs are located in single site or different sites..
----command should be successful.
repadmin /replicate dc1 dc2 CN=Configuration, DC=ad,DC=microsoft,DC=com this command is for replicate configuration partition between two DCs and dcs are located in single site or different sites..
----command should be successful.
repadmin /replicate dc1 dc2 CN=schema,CN=Configuration,DC=ad,DC=microsoft,DC=com this command is for replicate schema partition between two DCs and dcs are located in single site or different sites..
----command should be successful.
The following is an example of the syntax to show all replication partners for DC1 in the Microsoft.com domain:
Repadmin /showreps DC1.Microsoft.com
