Medisoft office hours won't conect to server

I work at a college tutoring center as their IT guy and we use medisoft office hours professional 12 for networks to schedule appointments with writing tutors and recently we installed a new server, on the new server I installed the advantage server software and followed the instructions on the disk but the computers we use to connect with office hours cant connect to the office hours data (they can connect to the server and if you pull up the data folders on windows explorer they are there it is just that office hours can not access them)
