Discovered something and just wanna share to avoid hiccups during the BES 5.0 software installation
If you are using default SQL instance
and do not customize to use other than the default port 1433, select static port
and set value as 1433
If you are using a named SQL instance
without any further modification to use a specific port, then select dynamic port
This is because - By default, a named instance of SQL Server listens on a dynamic port.

My experience is that if you have mismatch this settings, then you will not be able to launch the BlackBerry Administration Service webconsole.
Love sharing experience to help others avoid wasting time, which can be put to better use.
