One issue that can come up with Offline Files concerns how Windows should respond when a network connection is lost. In other words, if you are working on a cached file, can you continue to work on the file when the connection to the other computer is

Disk quotas do not prevent you from allocating more space than is available on the disk. For example, on a 40-GB volume used by 50 users, each user might be allocated 1 GB.

A new Group Policy setting allows you to specify the default owner of objects (such as files) created by members of the Administrators group. Access the Group Policy setting System objects: Default owner for objects created by members of the administrators group in

abruptly lost The choice is up to you. By default, when a network connection is lost, a message appears in the notification area informing you that you are disconnected from the network and that you can continue working offline with any folders and files you previously made available offline or that were automatically cached on your local computer. This is the usual behavior you ll want, but there are other choices available as well. To alter how your computer responds to going offline, open Folder Options in Control Panel, select the Offline Files tab, and click the Advanced button to open the Offline Files Advanced Settings dialog box, shown in Figure 15-6.

Local Computer Policy\Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options. In Windows XP Professional, the default owner is the object creator. To change the default owner to the Administrators group, use the Group Policy snap-in. For more information about using the Group Policy snap-in, see 5, Managing Desktops. Although members of the Administrators group do not have quotas enabled by default, you can set quotas for all members of the Administrators group except the built-in Administrator account. In Windows 2000, you cannot set quotas for any member of the Administrators group.

When you select Deny disk space to users exceeding quota limit on the Quota tab of the Properties dialog box, users who exceed their limit receive an Insufficient disk space error message and cannot write additional data to the volume without deleting or moving files. Individual programs determine their own error handling for this condition. The program treats the volume as full. By leaving the Deny disk space to users exceeding quota limit check box cleared, you can let users exceed their quota. This is useful to track use of disk space without denying users access to a volume. You can also specify whether to log an event to the volume host computer s system log when users exceed either their quota or warning level. Event Viewer keeps a chronological record of users who exceed their quota or warning level. However, it does not provide information about which users are currently over their quota warning level. Note

Use the fsutil behavior set quotanotify command to set the interval between quotarelated events that NTFS records in the system log. For more information about this command, see Windows XP Professional Help.

To delete the quota entry for a user, you must first do any of the following:

Permanently delete the files. Take ownership of the files and folders. Move the files to a different volume.

You have two options that govern how your computer behaves when a network connection is lost:

You cannot delete quota entries if a user owns files or folders on the volume. If you try to delete a quota entry for a user who still owns files or folders on the volume, a dialog box appears as shown in Figure 13-5.
