I am looking for advice on whether to move to a server based network. currently we have 3 computers, running peer to peer on XP (except for one on W98). We run a practice management program, as well as a document management program. The "main" computer has a tendency to freeze up fairly ofter. I am thinking it would be more efficient to use a server - I do not see us going past 5 computers. If the recommendation is to upgrade, I would appreciate advice on what what to look for, and what software to employ.
