    I want to schedule this defragmentation - currently it seems to run every 24
    hours after the last system reboot.

  2. Hello Amerera,

    Thank you for posting in the SBS newsgroup.

    According to your description, I understand that you would like to schedule
    the Online Defragmentation of the Active Directory Database (Ntds.dit). If
    I have misunderstood the problem, please don't hesitate to let me know.

    As I know, Online defragmentation is performed automatically by ESE at
    regular intervals following the garbage collection process. However, we
    cannot control the stop/start/scheduling of Online Defragmentation.

    I understand that this limitations may inconvenience our users and we
    apologize for the inconvenience you faced. In our efforts to continue to
    improve our products, I will send your comments on to our product group so
    we may use commentary such as yours to improve our services. We welcome
    your further suggestions in our www.microsoft.com/mswish link. Feel free to
    use this at any time.

    Best regards,

    Nathan Liu (MSFT)

    Yes you understood my question. Thanks you for your quick response.

    It is unforunate I can not control this activity. I will have to reboot the
    server in the middle of the night to ensure that this defrag only occurs at
    that time every 24 hours.

    The reason I was concerned was because I found that at the same time users
    had problems sending emails - they clicked send in their Outlook 2003 clients
    the emails did not go into outbox folder - only stayed in draft folder. The
    problem did not resolve itselve until MSExchangeSA messages appeared in the
    event log. See below for these messages - I am getting them 2-3 times each
    day. Do you want me to open a new thread or can you respond to this thread as
    to what I should do to stop the Exchange System Attendant service from
    stopping and starting 2-3 times each day?

  4. Hi Amerera,

    Thank you for your update.

    For the additional issue, based on our research, there are two most
    probable caused of the frequent 9095 and 9096 event issue:

    1. The most likely cause of this is a key in the HKCR registry hive that is
    longer than 259 characters. During initialization Exoledb scans the HKCR
    Hive to identify registered file types. If any subkey has a default value
    that exceeds 259 characters, this issue can occur

    2. It is also possible that this is caused by a permissions problem with
    the HKClassesRoot hive, or one or more subkeys within this Hive.

    You can use the HKCRScan utility to scan the keys and check on them. If a
    key value is correct, check the permissions setting for the key. After
    this, rescan with the utility. For more information, please refer to the
    following articles:
