I was trying to start the service but in vain. It gave me this error: "Could not start the Microsoft Exchange Directory Service on Local computer. The service did not start an error. This could be an internal Windows error or an internal service error. If the problem persists, contact your system administrator." Please could someone assist me to sort this problem. By the way if I copy the dsdata folder which is an older version it works. regards Thomas Kamire DISCLAIMER: This message and any attachments are confidential and may be legally privileged or otherwise protected from disclosure.
