I'm interested in setting up a local area network for my business. It's a small business and we have about 10 people each on their own computer as well as a separate computer (a tower with about 1TB of memory) that is used to store all the important documents (HR, Finance, Research, Client Related etc).
Now what I'd like to do is convert this separate computer into a server, which everyone can access (simply through a folder on Windows 7). They should be able to access the Research and Client Related documents but not the HR and Finance documents (which can only be accessed by the finance and HR managers and myself).
We thought of a concept that we aren't sure will apply in practice. Creating one LAN for the employees to access their data (Research and Client Related ONLY) and another LAN network for the F&HR managers and myself to access all of the data on the server.
Is this possible? Currently we all use Windows 7 while the separate computer runs Windows Vista. Will we have to purchase Windows Server 2012 or something similar?
Your comments will be extremely helpful! Thank you very much.
