If you can log in as root, do so. You should be able to reach the Mandrake Control Center, either from the Main Menu, or from a panel icon. In the "System" section, you can launch UserDrake to manage your users. From here you can add or delete users, change their passwords, and add them to groups if necessary.
As to the Samba problem; is Samba installed? Are the
smbd and
nmbd daemons running (look in the System Monitor if using GNOME, try KDE System Guard if using KDE, or in any DE, open a terminal and type
top and look for processes with these names)?
What is your network setup? Can you reach the Internet, just not the other PCs? Are you trying to ping them directly by IP address or by hostname? Have you used the Network and Internet Wizards in the Mandrake Control Center to set up your network connections?
Free games? You should have several installed by KDE and GNOME, if you installed either or both of those Desktop Environments, and Frozen Bubble is part of the Mandrake default install (since Mandrake supported the development of this great little game). If you need more, you should consider going to
Easy URPMI (assuming your network problems do not include Internet access) and using the instructions on that site to add some external repositories to your Software Media Manager. Once that is done, you will have access to all of the games in Mandrake repositories, and I think you'll find plenty to satisfy you. Just remember to change the default filter in Mandrake Control Center=>Software Management=>RPMDrake (Install Software) from "Mandrake Choices" to "All Software by...." and you'll see thousands of programs.
