Chapter 5: At a Glance Procedures
SharingToday's computers, operating systems, and networks have given us the unprecedented and often dizzying ability to share or gather information locally or globally. This interconnectivity, however, comes with a cost: the need for greater security to protect your computer and its contents from harm.You want the convenience and efficiency of being able to share the documents and files on your computer with your colleagues or coworkers, but you also want protection against lost information, hackers, prying eyes, and other evils. Microsoft Windows 2000 Professional was designed to meet those specific requirementsmaintaining security while enabling sharing. One of Windows 2000's primary security measures is the ability it gives you to classify users into groups, with each group having a specific level of permission to access or change items. You can share your files and folders but can limit or deny access to shared documents. You can monitor who's connected to your computer and what they can have access to. You can set up your computer so that you can share your printer with your coworkers, but you can also limit their access to the printer if necessary. You and your colleagues can collaborate on programs in an online NetMeeting session and can keep a text version of the online meeting for future reference. Sharing Your ComputerWindows 2000 initially sets up your computer to be shared by others. If your computer is part of a client-server network--and even if you never want to share any documentsfor administrative purposes your computer needs to be set up for sharing. If sharing has been disabled or removed, you can re-enable it or install it to enhance your connection to the network.
TIP: Hands off! Do not turn off the File And Print Sharing check box or uninstall sharing if your computer is connected to a client-server network. If you do, your documents might not be properly backed up and your computer configuration might be out of synchronization with other computers. Additionally, you'll probably receive a very sharply worded message from the network administrator. Enable Sharing

Groups, Permissions, and SecurityOne of the primary goals of Windows 2000 is to protect your computer from those who have no business reading your documents or modifying files and from your own desire to reconfigure the computer. One of the primary security measures is to classify users into different groups, described in the table at the right, with each group given a different level of authority, or permission, to access and change items. Some of these groups might look different on your computer, because someone with the proper permissiona member of the Administrators groupcan create new groups and modify permissions for existing groups.When you specify who can access a shared folder, you'll see more groups and a list of users, giving you even more options. In most cases, you can ignore the majority of the groups and either give permission to everyone or limit permission to a custom group or to certain individuals. Use the groups cautiouslyyou don't want to be responsible for allowing sensitive information to fall into the wrong hands. Permissions, of course, go well beyond allowing access to shared folders. When you log on, you're logging on as a specific type of user. Even if your computer isn't part of a large network and you don't care whether others can read your documents, you should still be concerned about security. For example, if you're always logged on as an Administrator rather than a User or a Power User, all the computers to which you're connected are as vulnerable as your own to viruses, hackers, and other evil forces that copy or delete documents, change system files, or reformat hard disks. For more information about setting up groups and assigning users to groups, see "Adding New Users" on page 284 and "Defining Access Rights" on page 287. Windows 2000 User Groups and Permissions
Sharing Documents and FoldersTo permit other people on different computers to access some of your documents, you share the folder that contains the documents. By specifying which groups have access and the type of permission each can have, you can limit access to the documents.
TIP: Slow computer. The greater the number of people who are connected to your computer and are using its resources, the more slowly your computer will run. If its sluggishness becomes unbearable when several people are connected, you'll want to consider reducing the number of people who can connect at one time. Share a Folder

TRY THIS: Prevent accidental changes. You can prevent accidental changes to some of your shared documents while allowing full control over other documents in the same folder. To do this, right-click the document, choose Properties from the shortcut menu, turn on the Read-Only attribute, and click OK. Note that turning on a document's Read-Only attribute will prevent a user from accidentally saving changes, but he or she can still make changes intentionally by turning off the Read-Only option. TIP: No sharing. If the Sharing command doesn't appear on the shortcut menu, either you don't have the authority to modify folder sharing or sharing hasn't been set up on your computer. SEE ALSO: For information about specifying individual access to shared folders, see "Limiting Access to a Shared Folder" on page 82. Set the Access
