Make Vb.net desktop application with sql server 2008 databse accesible in a network..

Hai All,
I have made a desktop application in Visual studio 2010 in vb.net with sql server 2008 as backend.I have made the setup of the project ,with sql database to be created using installer class and its all working well and fine. but i want to make my application in such a way that it has to be installed in one computer , and make the application and database be accessible to all computers in that network.How can I do that and do i have to make my setup again to make the changes?
any helpful suggestions requested.
Thanks In Advance
