Part II ✦ Planning and Setting Up Networking — Hardware and Software • Second, everyone needs to enter a password. Windows 2000 and XP expect to see a password and will not authenticate unless there is a password. • Then make sure that the users and passwords are entered into the Windows 2000 andor XP computers. You open the Control Panel and double-click Users and Passwords. Add a new user and the password to match those the user enters on his or her own computer. ✦ Beyond authentication issues, if you still cannot see other computers in the Network Neighborhood or My Network Places, you can look for a few other things to solve that problem: • First make sure all the computers have the same setting for Workgroup, whether it’s your family name, a pet’s name, or even the word workgroup. All computers must have the same setting. • Second, make sure all computers have the same protocol, Client for Microsoft Networks, and the same services: file and printer sharing. • Third, make sure each computer name is unique; you can use each family mem- ber’s first name as their computer name, for example. Windows 2000 and XP support some computer names that are not compatible with Windows 98 or Me. If your computer names are not similar in length, for example, rename the computers and try again. ✦ If you’re using Windows XP’s built-in Internet Connection Firewall, you have to do some tweaking to enable file sharing through the firewall. See Chapter 16 for more information. If you are having networking problems, be sure to consider you might have a problem with a network interface card NIC or cable. Using Portables on Your Network Portable computers include tablets, notebooks, and handheld computers. If your notebook or tablet uses the Windows 98, 2000, or XP operating system, you need only install the hardware and configure the software as you would with a desktop computer. Even Macintosh notebooks PowerBooks connect to a network easily. If you want to add a handheld computer to your network, the process is a bit different. Using notebooks or laptops on the network You can attach notebooks or laptops to the network by using the same cabling types — Ethernet, phone lines, wireless connections, and so on — and you use similar networking hardware on these portable computers as well. Of course, there are some exceptions. For example, you must use a PC Card PCMCIA network interface card on a portable computer. Check your notebook’s documentation for other changes or problems. Today, laptops and notebooks are pretty much the same thing. In past years, notebooks were smaller and lighter in weight than laptops, but the name is now used interchangeably for both. Note Tip Tip
