1. Microsoft Windows has two destinctive ways of logging onto a machine. An interactive logon is where you log onto your machine locally (sitting in front of it), whereas a network logon is the process of connecting to the file server remotely across the network. Normally, both logons happen simultaneously after entering the username/password only once, so users typically don't perceive much difference between the two logons. Key point: Network logons can be disabled for administrators. This prevents people from stealing passwords and remotely administering the machine. This makes security easier because the server can be controlled via physical security. Contrast: Unix has similar concepts. A local logon is through the "console". Often, root access will be denied to remote logons. Both Windows and Unix have the concept of remotely logging on via one user account, then using that account to locally upgrade to root/administrator. From Hacking-Lexicon
