Windows 7: Windows server 2008 r2, or 2011

Hi, I hope I'm posting in the right section. Especiall since this is windows 7 based forum.

I had near the same dilemma a few years back, and now I have the opportunity to get a server and some client computers for cheap from an office closing. I'm being offered either a dual core work station that have windows server 2008 loaded or a quad core server with server 2011 small business. Then some workstations with windows 7. I pretty much need some advice and path of direction, because I'm beyond rusty with server 2008, and 2011 I only helped a friend installed it a while back. What I want accomplished is to be able to do the following:

• Log off one workstation as a certain user account then log back on through another workstation with the same account and have access to all my previously saved work. (maybe virtualization?)
  
• have certain network drives setup for each user account
  
• Setup a vpn to synchronize certain folders.
  
• Have the user accounts and data on the server.
  
• setup printing limits.

Pretty much Even though I'm not there yet in the real world I'm trying to emulate an office network. Currently, I have 2 routers and a switch. The main router has on dd-wrt and handles dhcp, and the other router is pretty much an extension. Any advice and help is appreciated. I'm leaning towards the dual because it's cheaper, but I can try to sell my laptop to get some money for the quad core.



Can I also create "guest" like accounts that have no access to certain items and will not attach all drives? Do I have to install the programs on the local computer, or should I install them on the server? Is this something I should do in another os like linux? I was thinking windows server since its pretty much a windows network, and since it's being included.

So far what i'm thinking for the network drives is a logon script but don't know where to have it set up on. I'm thinking that if everything is done through the server, then I can deploy it via the active directory user list maybe? They also have some terminals there, but since I have a few desktops I don't think I'm interested. I do have a bit of curiosity on how those are setup.

I found some info, it seems as if I have to use a domain controller. I know it houses a user database, but is the content and any information that is for the user account handled locally on the workstation or the server?

Get the quad core server...if you can...either way. Windows Server Small Business 2011 is in fact Windows Server 2008 R2...that is basically a pack of other Microsoft software. With a Domain set up, the server handles the user authentication, but can still log on locally if you need to.
