25 PCs and no server :shock: ?
What about security? You've no way of recording who's accessing what, despite the file share arrangements.
What about bottle-necks? You can't tell if the sytem is meeting your needs or if data on one client is too heavy. I don't know if you're using a router or a hub, but might data collision be a problem?
What about disaster plans? What about backups?
What about convincing your boss that it would be an economical use of your resources for you to configure a server which would automatically do the housekeeping on 25 clients. Right now you're looking after 25 individual machines - a server would enable you to look after 25 machines collectively.
Crikey, no wonder you need help automating administrative processes!
