Click the Computer Name tab. 4. Type text into the Computer text box. You directly add or change the name this way. No requirement says a computer must have a description. 5. Click the Change button. Now you can make changes to the full computer name, or to the work- group name. Each computer name on a network must be unique, and there can be no spaces in the name. But when it comes to workgroup names, they need to be the same on each machine that claims membership; any differences will cause the operating system to consider the two groups to be separate. Figure 2-5: The direct way to changing a computer’s or work- group’s name under Windows Vista is displayed by entering a command in the Start menu search box. 40 140925-bk08ch02.qxp 4/8/08 12:51 PM Page 504 Book VIII Chapter 2 Managing a Windows Network Your Laptop’s Name and Address, Mac 505 Finding your laptop’s IP address in Windows Vista Here is one way to learn the IP address (and much more) for a computer suc- cessfully connected to a network, under Windows Vista: 1.

Playing Nice, Sharing a Folder To make a folder on a desktop or laptop available to other authorized com- puters in the same Local Area Network, it needs to be shared. The folder can be shared with only those users with accounts on the laptop you are config- uring, you can open it up for access by anyone on the network, or you can give permission only to specific users. When you share a folder you are making available all of its contents, includ- ing those of subfolders held within. Individual files can’t be shared; they must be placed within a shared folder to be accessible. In most cases, you don’t want to share the root folder (the topmost folder of a disk drive) or any of the system folders that hold Windows and its settings. Keep this unavailable to avoid intentional or unintentional damage to your essential system files. Sharing a folder under Windows Vista Windows Vista allows sharing of files from any folder where permission is granted, or from the Public folder. A shared folder and the files within can be 40 140925-bk08ch02.qxp 4/8/08 12:51 PM Page 506 Book VIII Chapter 2 Managing a Windows Network Playing Nice, Sharing a Folder 507 accessed by anyone logged onto your computer or by someone on another computer on the network. If you share files from their current location without copying them to another location or to the Public folder, you can specify which users or machines can have access. To do this, follow these steps: 1. Locate the folder with the files you want to share. 2. Click one or more files or folders. 3. On the toolbar, click Share. The File Sharing dialog box opens. 4. Click the text box’s drop-down arrow. 5. Click the name of a person previously identified to the network. 6. Click Add. You can also type the name of the person you want to share files with, and then click Add. If you don’t see the name of the person with whom you want to share files, click the text box’s drop-down arrow and then click Create a New User. If password protection is turned on for your computer, the person you’re sharing with must have a user account and password on your computer in order to access the files and folders you’re sharing. You can turn password protection on or off in the Network and Sharing Center. Once you add a name to the list of people who can share a particular folder, you can also set permissions for users. See Figure 2-7. 1. Click the drop-down arrow under Permission Level for each name. 2. Select one of these options for each name: • Reader. This gives read-only permission to another user; that person can view shared files but cannot edit or delete them. • Contributor. Users with this level of permission can view or add shared files, but can only edit or delete files they have contributed. Contributor status is only available when folders are shared; individ- ual files can’t be given this permission level. • Co-owner. These users can view, add, edit, or delete any shared file. 40 140925-bk08ch02.qxp 4/8/08 12:51 PM Page 507 Playing Nice, Sharing a Folder 508 Notifying other users of changes to sharing settings Once you have completed setting sharing for a folder or file you will receive confirmation from the system. You may want to notify other uses that a folder has been shared or permissions otherwise changed. Windows Vista helps notify: ✦ Click E-mail to open a Windows Mail e-mail message containing a link to your shared files; enter the e-mail addresses for the proper recipients. ✦ Click Copy to automatically copy the displayed link to the Windows Clipboard. You can then open an e-mail program or instant message (IM) program and paste the link into the message. If you change the name of a file or folder after you it has been shared, any link you sent to other users will no longer work; you must send them a new link or otherwise notify them of the change. Sharing files in Windows Vista with the Public folder To share files from the Public folder, copy or move files to the Public folder or one of its subfolders, such as Public Documents or Public Music. Anyone with a user account on a particular computer can access the Public folder on that machine; in addition, you can decide whether to extend that folder on the network. Figure 2-7: When you choose people to share network access in Windows Vista, you can assign three levels of permissions. 40 140925-bk08ch02.qxp 4/8/08 12:51 PM Page 508 Book VIII Chapter 2 Managing a Windows Network Playing Nice, Sharing a Folder 509 Anything in the Public Folder is open to viewers with permission to access it; individual files and folders located there can’t be restricted. By default, network access to the Public folder is turned off; you have to turn it on if you want to enable sharing. You can also turn on password-protected sharing to limit network access to the Public folder to only those with a user account and password on your computer. Assigning permission levels to users You can set specific permissions for individual folders or groups of folders. You also can set varying levels of general permission for users. The right to assign permission levels to users is given only to system admin- istrators and users with administrator accounts; if you are the only user on your laptop, you’re likely to be the administrator unless you’re working with an organization that configures and manages laptops for users. Available permission for users follow: ✦ Full control. Users can see the contents of a file or folder and make changes to existing files and folders as well as create new files and folders. They can also run programs from a folder. ✦ Modify. Users are permitted to make changes to existing files and folders but cannot create new ones. ✦ Read & execute. Users can see the contents of existing files and folders but cannot make changes to them or delete them. They can also run programs from a folder. ✦ Read. Users have read-only access to folders and the files within them. ✦ Write. Users can create new files and folders and make changes to exist- ing files and folders. Sharing a folder under Windows XP Here’s how to share a folder in Windows XP: 1. Go to My Computer. Any other Windows Explorer display (including My Documents, My Music, and My Pictures) will do, too. 2. Click the folder. The folder’s highlighted. 40 140925-bk08ch02.qxp 4/8/08 12:51 PM Page 509 Accessing Another Computer on a Local Network 510 3. Do one of the following: • Right-click and choose Sharing and Security. • Choose File ➪ Sharing and Security. A Properties dialog box appears. 4. Locate the Share This Folder on the Network check box. It’s in the Network Sharing and Security pane. 5. Choose one: • To share the folder: Add a check mark to the Share This Folder on the Network check box. • To remove sharing permission: Click an existing check mark in the Share This Folder on the Network check box. You can’t share the folder if it’s marked Private in the Local Sharing and Security pane on the same dialog box. 6. Enter a Share Name text box. A share name is a nickname that appears on the screens of other users in the network. You can use this to make the folder name more descrip- tive of its contents. 7. If you think it’s safe, you may enable the Allow Network Users to Change My Files check box. Stop and think before permitting others to alter your files. It is one thing to allow others to retrieve information from your computer and some- thing completely different to allow them to change your data. On the other hand, if you’re setting up a network for your own benefit — for example, preparing your laptop and desktop to exchange files for your Road Warrior travels — this facility allows that process to be done easily. When you’re finished making settings regarding sharing, the folder’s icon changes to show an outstretched hand beneath its picture. Accessing Another Computer on a Local Network Once you set up your computer’s networking facilities, you can see any shared folders or resources offered by computers on the network. Windows XP and Windows Vista operate in a similar fashion.
