Your Linux server has been set up to run web service and pc file service. When the server starts up, you can see messages about all the services that are starting up. When it is done starting up, it will give you a login prompt. The server works without you needing to log in. You only need to log in if there are problems with the services or if you need to add a user login or change a password. This server should NOT BE SHUTDOWN. Just leave it running. (You can turn the monitor off, though). LEAVE THE SERVER RUNNING ALL THE TIME. If it is turned off for any reason, just turn it back on.
If you do need to log in, you have been provided with the master user's login information (username: root, password: ...)
If you do log in as root, you will see some icons on the desktop. The most useful is the one for "root's home". This is a shortcut to the home directory for the user root (/root). In this directory, I've provided some scripts to perform some important tasks, such as creating new user logins (addpcuser), changing passwords (changepassword), and adding new PC's to the server's domain (addmachine). (Note: you are prompted for the password FOUR TIMES when you use addpcuser or changepassword. This is because you are actually making entries in two different password systems: the linux password file (/etc/passwd), and the samba password file (/etc/samba/smbpasswd). The scripts take care of these things for you).
The user login creation scripts, addpcuser, also creates a login command file that maps network drives for each user. These drives show up in "My Computer". For example, the user's home directory is H:, the group shared folder (e.g. student) shows up as S: or T: and so forth. There is also a read-only share called "public" that shows up as the P: drive.
Most users should save into the group shared folder (e.g. S:) and not the home directory (H:) or the local drive (C:).
There are three advantages to saving to the network drives instead of the local drive C:
