How to get a list of SQL Servers on network

Hi !

Using D5 Entrprise, how can I get a list of all SQL Servers on our
network ?

The TADOConnection has a property editor for the ConnectionString that
allow the programmer to build the string. In the Connection tab, there
is a list of "server names" I would be happy to reproduce in my
application.

My goal is to avoid poping a dialog for the user to enter this
information.

Can someone help me on this one ?
