Access Database on Server HELP!!!!

Hi!

My employer is needing help trying to figure out if it will be beneficial for him to purchase a server or not. Hopefully someone can help us! We have a simple Access Database with forms and reports that we want to share with all of our other facility locations for those people to be able to view,add,& modify their information. We want to purchase the Windows Small Business Server 2003 and put the database on there. The only question we have is will everyone who needs to use the database in the other locations have to have MS Access installed on their computers?
