Learning about serv/network administration

[Bakedgoods]

What would be the best way to teach myself more about server and network administration from home?

For example, setting up a managed network at home with user groups and profiles etc? Although i'm studying for a CCNA at the moment I feel i'm missing out on this and i'm interested in getting at least some basic experience.

I have no idea how to stop someone pluggin into a network and using the network resources without having to log in (assuming they are physically able to connect).

Anything people can recommend? Certain books etc?

Cheers guys

Well, can't you just only grant people who are authenticated or have a paticular hostname for example onto the network? I know you can do this with active directory.

What I mean is though, if someone with a machine that isn't yours (so it wont be configured to have to log on), will they be required to logon or will it simply just book up as normal?

I know these are pretty stupid questions...
