replication does not work on one DC RRS feed

  • Question

  • Hi all,

    Windows 2008 R2 SP1

    We found out that replication fails on this DC as we have multiple DCs at multiple sites.

    check the directory service log and find out the event id 474

    Log Name:      Directory Service
    Source:        NTDS ISAM
    Date:          12/10/2012 9:08:28 AM
    Event ID:      474
    Task Category: Database Page Cache
    Level:         Error
    Keywords:      Classic
    User:          N/A
    Computer:      DC6
    Description:
    NTDS (496) NTDSA: The database page read from the file "C:\Windows\NTDS\ntds.dit" at offset 132931584 (0x0000000007ec6000) (database page 16226 (0x3F62)) for 8192 (0x00002000) bytes failed verification due to a page checksum mismatch.  The expected checksum was [92da6d25e0b99bbf] and the actual checksum was [90586fa7c17f4529].  The read operation will fail with error -1018 (0xfffffc06).  If this condition persists then please restore the database from a previous backup.  This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem.

    then followed event 1084 and event id 2108

    How should I troubleshoot this?

    Thank you.

  • Event ID 2108 and Event ID 1084 occur during inbound replication of Active Directory in Windows 2000 Server and in Windows Server 2003:http://support.microsoft.com/kb/837932

    Also verify the health of disk run chkdsk in read only mode if error is reported take full backup of server and perfrom chkdsk/f.Also exclude the ntds/ntfrs and sysvol folder from AV scan.Check the device drivers it should be updates with latest hotfix and service pack installed on server.

    Check the integrity of AD database and perfrom semantic database analysis and run go fix if required.If this does not work then you need to defrag the AD database to get is fixed.http://support.microsoft.com/kb/258062

    Please take full backup of server before you proceed.

    Hope this helps

  • If you have other DCs & there is no other application in the probmetic DC; backup is not required coz every DC has hold same database.

    If there is other applications are installed in the probmetic DC then only you need the backup. like DHCP,WINS, NPS & so on.
