    This process is automatic. KCC automatically create optimized connection objects for replication. So, just keep a check on the event viewer. In Directory Service event logs check if you see any errors related to replication.
    In the File replication service logs if you have event id 13516 then the replication is working fine. If at any time you see 13508 and 13509 then you will have to check if the connectivity is reliable. Also keep a check on system logs.

    run repadmin /replsum

    It will show you the results. If there are any replication issue, if will show the error in the result.

    ashutosapre: is see some 13508 from previous day on DC1. Let supposed i have DC1,DC2, DC3.
    the event properties is reading as:
    The file replication service is having trouble enabling replication from dc3 to dc1 for c:\windows\sysvol\domain using the dns anme FRS will keep retrying. Following are some of the reasons you would see this warning........[1] FRS can not correctly resolve the DNS name form this computer.
    [2] FRS is not running on
    [3] the topology information in the active directory for this replica has not yet replicated to all the domain controllers

    i put the commands on dc1 and it does not any fails. All good and suceess.

    you can either use Replmon.exe or go for Spotlight for AD monitoring this will give you the detailed reports on Replication, DC health, dns etc...

    Based on the output you reported, it definitely sounds like some problems on your DC's
    Run DCDIAG on each server to confirm the health of your Active Directory installations.
    Once the errors in your DCDIAG's have been resolved then you shouldn't have any replication errors.

    Repadmin is the best command to fix the replication issue. Below are the troubleshooting steps for AD. Hope this will help you a lot

    Troubleshooting Steps

    Critical Errors

    Event ID: -- 467 – Directory Service Event
    Indication – AD Database table has been corrupt.
    Resolution – Perform a offline defragmentation of AD Database or Remove the AD database from the server and reinstall AD.

    Warning Errors

    File Replication Events

    Event ID: 13508 – Unable to create RPC connection to replication partner
    A single FRS event ID 13508 does not mean anything is broken or not working, as long as it is followed by FRS event ID 13509, which indicates that the problem was resolved.
    Check for Event ID 13509 after 13508 if not troubleshoot the event 13508
    Resolution – Stop and start the File Replication service.
    1. Run --> cmd --> net stop ntfrs (stopping the service)
    2. Net start ntfrs (starting the service)
    Note: Stopping and starting the service should be done strictly after business hours.

    Event ID: 13568 – Indicates FRS is in Journal Wrap state
    How to perform nonauthoritative restore.

    1) Open command prompt on DC, type net stop ntfrs
    2) Goto Run> Type Regedit
    3) Browse to below path
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup
    4) In the right side window, select BurFlags and double click to open it
    5) Type D2 in the Edit DWORD Value. Click ok and exit from Regedit snap-in
    6) Open command Prompt again on DC and type net start ntfrs
    7) Open Event Viewer and in FRS logs you will find 13565. This indicate restore process is started
    8) Event ID 13516 will indicate restore is completed.

    For more details:

    Directory Service Events:
    Event ID: 1925, 1311, 1865, and 1566 --- These Events indicate KCC (Knowledge Consistency Checker) Errors
    1) Check there is no network issues in the site.
    2) Check the DC by running a Basic DNS test. (Run --> cmd --> dcdiag /test:dns /s:sourcedomaincontrollername /Dnsbasic).
    For EX:- dcdiag /test:dns /s:YOURDCNAME /Dnsbasic
    3) Check DNS Registration by running the following command.
    Dcdiag /test:dns /DnsRecordRegistration.
    Event ID: 1079, 1169 --- This Event is trigerred if Active Directory is unable to perform replication if there is a low memory to perform the operation.
