Posted on 2009-02-19
Last Modified: 2012-05-06
We have started having random issues with our exchange server over the last coulpe of days (when creating mailboxes through AD tools they don't always get created, random outlook disconects/reconnects, etc)  I have been searching for a solution for this for several days and happened to click on the Security section of the Event Viewer and noticed about 19,000 of the below errors.  Hopefully someone can help me out with this, as google and all of the other admins I know have no explination.  Thanks!

    Accepted Solution

    I would start by running the domain prep again.
    Then run the Exchange Best practises tool on the server and see what that throws up.

        As a quick follow up.  As this is a "working" (as far as user can tell) production exchange server, is there anything special I need to be aware of before I run domain prep?  (If there is a site that covers this a link would be fine.  Google has failed me again :-/ )

    Domain prep is non-destructive. It can be run in production hours and does not make any changes that would affect the operation of Exchange. It simply corrects permissions within the domain that Exchange requires.
