Pulls a list of processes from the remote server over SMB. This will determine all running processes, their process IDs, and their parent processes. It is done by querying the remote registry service, which is disabled by default on Vista; on all other Windows versions, it requires Administrator privileges.

Enumerates the users logged into a system either locally or through an SMB share. The local users can be logged on either physically on the machine, or through a terminal services session. Connections to a SMB share are, for example, people connected to fileshares or making RPC calls. Nmap's connection will also show up, and is generally identified by the one that connected "0 seconds ago".
