  • The “OriginatingServer” property indicates which DC the data is read from and is used primarily for troubleshooting. It is updated with each AD call so that it could change during different runs of “get-*” cmdlets

    Are both DC01 and DC02 in the same AD site? If so, why does it matter
    which DC is uses?

  • Yes both of the DC are in the same domain and IP subnet, but for some unknown reason they changed by itself ?

    Are you asking about the "configuration domain controller"? Perhaps
    the machine was rebooted or otherwise inaccessible for a while?
     
    If it's not the configuration DC then the DC used by Exchange will
    vary depending on the number of pending LDAP requests. Once they
    exceed a certain number (it used to be 20) the Exchange server will
    switch to another DC within the AD site.
     
    Where are you seeing the DC name?

  • Filter your application logs for event ID 2080.  After analyzing them all, you should be able to answer your own question.
