    We are running a Windows 2003 SBS server on a very small network and are
    getting the same 3 error messages in the Directory Service event log as
    follows:

    Event Type: Error

    An attempt to complete the topology for this site will be tried again at the
    next scheduled KCC interval (the current default is 15 minutes).

    Additional Data

  2. Hi,

    Thank you for your post.

    According to your description, I understand that you encountered some error
    message in event view. If I am off base please let me know.

    Based on my research, it appears that we need to perform an offline
    defragmentation.

    Use the following procedures to perform offline defragmentation. Procedures
    are explained in detail in the following articles:

    Active Directory Operations Guide
    Appendix A - Tasks Reference
    http://www.microsoft.com/technet/prodtechnol/windows2000serv/technologies/ac
    tivedirectory/maintain/opsguide/part2/adogdapa.mspx#EUAA

    Appendix B - Procedures Reference
    http://www.microsoft.com/technet/prodtechnol/windows2000serv/technologies/ac
    tivedirectory/maintain/opsguide/part2/adogdapb.mspx#E0CE0AA


    1. Back up system state. System state includes the database file and
    database log files as well as SYSVOL, NETLOGON, and the registry, among
    other things. Always ensure that a current backup exists prior to
    defragmenting database files.

    2. Take the domain controller offline, as follows:

    If you are logged on to the domain controller locally, restart the domain
    controller in Directory Services Restore Mode.

    If you are using Terminal Services for remote administration, you can
    remotely restart the domain controller in Directory Services Restore Mode
    after modifying the Boot.ini file on the remote server.

    3. Compact the directory database file (offline defragmentation). As part
    of the offline defragmentation procedure, check directory database
    integrity.

    4. If database integrity check fails, perform semantic database analysis
    with fixup.

    Hope the above information helps, if you have any further issue, please let
    me know. I am standing by to be of further assistance.
