BESUserAdminClient - "Cannot find Dispatcher Instance:"

BESUserAdminClient requires -b parameter with some of its switches. As per the document -b is the name of the BlackBerry Server Instance that appears in the BlackBerry Administration Service.

There are many ways to find it, that includes BlackBerry Administration Service, BES SQL Server, Registry and the BESUserAdminClient itself. 

If you get an error message "Cannot find Dispatcher Instance:" when using BESUserAdminClient,then surely the issue is with the -b parameter.

How to get the Dispatcher Instance from BlackBerry Administration Service

Under the section Servers and Computers -> Click BlackBerry Solution topology -> Click BlackBerry Domain -> Click Component View -> Click BlackBerry Enterprise Server . On the right side of the screen, Click on View component list. On the Components Page note the Name under BlackBerry Enterprise Server Section. You can use the Name as the Dispatcher Instance name for the -b parameter used in the BESUserAdminClient.

Hope this helps. Enjoy the automation.
