Failed to retrieve the Server DN, shutting down


We start receiving fallowing message on the BES servers and "Failed to retrieve the Server DN, shutting down"


The BB service account is corrupted with un-known reason ( we are un-able to find the cause)

Event Type: Error

Event Source: BlackBerry Messaging Agent SMTP25WINBES01 Agent 200

Event Category: None

Event ID: 10275

Date: 2/23/2009

Time: 10:42:48 AM

Failed to retrieve the Server DN, shutting down

Event Type: Warning

Event Source: BlackBerry Controller

Event Category: None

Event ID: 20406

Date: 2/23/2009

Time: 10:00:35 AM

User: N/A

Computer: SMTP25WINBES01


'SMTP25WINBES01' agent 1: will not restart - reached the maximum of 10 restarts per 24 hours


This is one of the weird error and researching the cause did not much help to us. So we went ahead and basically performed fallowing steps

  1. Re-start the BES services ( Problems exist)

    If you remember this needs to be done in order, others fallows as you wish in any order.

  • R ( Router)
  • D (Dispatcher)
  • C (Controller)
  1. Reboot the BES server ( problem exist)
  2. Check BES account verified it is not locked
  3. Check server DNS setting TCP/IP made sure DNS IP addresses have not been changed
  4. WINS configured ( if there is one)
  5. Flushed TCP/IP configuration, Un-Registered and registered WINS server
  6. Open BES logs continue to look for errors
  7. Re-start BES services in order
  8. Re-configure the BES profile on the BES server ( Problem persist)
  9. Finally we create new BES service account , configure profile and give proper permission on the exchange 2007 server, made all worked out.

For me, the error had to do with the besadmin mailbox missing the 'HomeMTA' attribute. I took the homeMTA from another mailbox on the same Exchange server and applied that to the besadmin account and that fixed the problem.
