John is completely right. This is where client/server is an advantage over peer-to-peer. While you could sort of set things up similarly on a "main pc" as far as permissions, it brings up issues you would have with server/client.
When you think of a folder and how you share it, think of this way. The first thing you do is to set up shares. What clients and users have access to the folder over the NETWORK. Then with the advent of NTFS, security made a huge leap. Think of NTFS permssions as those that control the folder as if you were on that computer. In order to properly secure resources, you need to have at least a minimal understanding of shares and permissions. They are not the same.
EVERYTIME you set up data on your server whether it is the Amazing Charts folder or your Billing software or even your pictures from the beach. Once you set up the data, sit down and say who do you want to access this and how much do you want them to access. Do they get read only, read/write, editing, deletion. The ultimate test for you, the admin, is to make sure you can go to any client and browse to the folder, create a text file, write on the text file, save the text file, then delete the text file. But, you don't want users to be able to do that.
So, say you make a folder on the server that contains the AC backups, forgetting the auto backups (which makes my head spin), you must make sure that the program can access it and you must make sure you can access it. Your staff should never be able to access it either from their computer or from the server computer as they should never be able to get on the server.
This is what makes YOU the SYSTEM ADMINISTRATOR. And, you are, you just don't know it. You just want to become a better systems admin.
Another nice thing about a server/client setup is you know WHO logged into that server exactly when. I am anal about passwords for clients. They know to log off and let another person log in even if they are going to the bathroom. They only access Medware, FAP or AC from their account. And, their passwords are made by me, because I can't accept a password created from their dog and their birthday. Letting someone use their password is not punishable by termination (too harsh) or a slap on the wrist (too easy), but by losing their Internet access over lunch. Facebook has become the number one form of discipline for employees. But, all they have to do is walk over and use Employee B's facebook. And, now they have lost facebook for three lunches AND, the person's computer they used has lost it for three.
Whether they are on the Internet or not is a different discussion. I used to allow it all day, but I think lunch hour is a decent compromise. And, they can get their banking done, etc. Because God knows I pay them so much!
In 1997, I bought a Dell with 2GBs. I sold it on eBay. Ken, did you buy it?
