  • After 8Hrs this server automatically connected to Domain and mail delivery started.The problem was in night.

    My doubt is....

    we have 4 mailbox server

    If one mailbox server  down other will take role right?.Why this feature not working.

    I have checked DNS resolution and it is working fine.

    Mailbox will Look for mailbox Server

     

    if mailbox server found and respond to another server than its ok for mailbox.

    1. At some point during that time, your Exch server couldnt reach the DC, what the cause for that was,needs investigating.
    2. Your mailbox server wasnt down, so if you were expceting other mbx servers to take over then that probably wouldnt have happened as it wasnt a database failure.
    3. The event you posted above shows an possibly cause for your issue - http://www.microsoft.com/technet/support/ee/transform.aspx?ProdName=Exchange&ProdVer=8.0&EvtID=2102&EvtSrc=MSExchange+ADAccess&LCID=1033

    Can you post the actual details of the errors? You can change the DC names. The 2080 errors should show what DCs that mailbox server is using/

     No need to post all of them, just a sample when it worked and when it didnt.

  • I've seen this before.  There seems to be a bug in the topology discovery service.  Once it loses contact with a DC, it never re-discovers it on subsequent attempts, and eventually runs out of discovarable DCs. 

    The Exchange Toplogy Discovery Service connection to the DC is left in a close-wait state, and you cannot even restrart the discovery service until that close-wait condition is cleared.

    I believe right now the only fix is to hard-code the DCs for each server.


    [string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "
