You will need some way to network these machines first. I'd recommend a simple 4 port switch. To keep things simple, just put Linux onto the old computer. Go back to your vista machine and enable file and printer sharing. Go back to the Linux machine and locate the drive.
As a side note about a similar situation. About 2 years back I had one good high end machine and a very crap laptop. I configured a new wlan and pretty much for about a year, I walked bout the house with the laptop remotely logged into the good computer. All the functionality of a laptop and all the power of top range PC. One or two small hicups but nothing you cant get over. You could have a similar setup.

Network Layer
RRAS (Routing and Remote Access service)
Network security concentrates on the packets of information flowing between computer systems.Operating System security controls access to resources on the server itself.Therefore, the two are looking at different things in terms of security.

single user os are those os where only one user access the resources of the operating system at a time .the resources of operating system 'll not allocate to any other user.multi user operating system is that operating system where the resources of operating system can be accessed by more than one user at a time ,means to say; multi users can access the operating system simultaniously or any other way.network user operating system is also the multi user operating system but the different is that the users are geographically remote user connected through a network media but share the same capy of operating system
