WIX Install Script to Check SSRS Existence
I'm using the script below during my WIX Installer to validate SQL settings input by the user.
I need to expand this, to add a new function, that will check the existence of the specified Report server [REPORTSERVER]. When the user clicks the next button after entering the reportserver address, I need to somehow validate that it does exist.
Has anyone done anything like this?

' This script handels all database checks and interaction
' before the installation process takes place. that means
' it checks if a connect is possible, if the user has the:
' - right to create databases
' - right to create new users
'
' And if the database only supports windows authentification
' or sql authentification as well (is a must).
'
' This script also contains functions to propose a username,
' a database and a sql user password. There are also checks
' if the chosen values for username, database or password
' are valid.

You could just try to open a connection to the sql server and catch the failure / error code if this does not work out.
