BlackBerry Controller error 5003

After I rebooted our Blackberry server today the Blackberry Controller service would not restart and the system log showed ‘error 5003′.

I did the following to fix the issue:

  1. Stop the DNS, start the BlackBerry Controller service, and then restart the DNS.Note: The issue could potentially occur again when the computer is restarted.
  2. Modify the value of the Syslog User Datagram Protocol (UDP) port using the HKEY_LOCAL_MACHINE\Software\Research In Motion\BlackBerry Enterprise Server\Controller\SysLogPort registry key to utilize port 4071 and restart the BlackBerry Enterprise Server services. Note: If the SysLogPort registry key is not be present, it can be created as a DWORD key before performing the workaround.
