Specifies if the devolution level that DNS clients will use if they perform primary DNS suffix devolution during the name resolution process. With devolution a DNS client creates queries by appending a single-label unqualified domain name with the parent suffix of the primary DNS suffix name and the parent of that suffix and so on stopping if the name is successfully resolved or at a level determined by devolution settings. Devolution can be used when a user or application submits a query for a single-label domain name. The DNS client appends DNS suffixes to the single-label unqualified domain name based on the state of the Append primary and connection specific DNS suffixes radio button and Append parent suffixes of the primary DNS suffix check box on the DNS tab in Advanced TCP/IP Settings for the Internet Protocol (TCP/IP) Properties dialog box. Devolution is not enabled if a global suffix search list is configured using Group Policy. If a global suffix search list is not configured and the Append primary and connection specific DNS suffixes radio button is selected the DNS client appends the following names to a single-label name when it sends DNS queries:The primary DNS suffix as specified on the Computer Name tab of the System control panel. Each connection-specific DNS suffix assigned either through DHCP or specified in the DNS suffix for this connection box on the DNS tab in the Advanced TCP/IP Settings dialog box for each connection. For example when a user submits a query for a single-label name such as “example” the DNS client attaches a suffix such as “microsoft. com” resulting in the query “example. microsoft. com” before sending the query to a DNS server. If a DNS suffix search list is not specified the DNS client attaches the primary DNS suffix to a single-label name. If this query fails the connection-specific DNS suffix is attached for a new query. If none of these queries are resolved the client devolves the primary DNS suffix of the computer (drops the leftmost label of the primary DNS suffix) attaches this devolved primary DNS suffix to the single-label name and submits this new query to a DNS server. For example if the primary DNS suffix ooo. aaa. microsoft. com is attached to the non-dot-terminated single-label name “example” and the DNS query for example. ooo. aaa. microsoft. com fails the DNS client devolves the primary DNS suffix (drops the leftmost label) till the specified devolution level and submits a query for example. aaa. microsoft. com. If this query fails the primary DNS suffix is devolved further if it is under specified devolution level and the query example. microsoft. com is submitted. If this query fails devolution continues if it is under specified devolution level and the query example. microsoft. com is submitted corresponding to a devolution level of two. The primary DNS suffix cannot be devolved beyond a devolution level of two. The devolution level can be configured using this policy setting. The default devolution level is two. If you enable this policy setting and DNS devolution is also enabled DNS clients use the DNS devolution level that you specify. If this policy setting is disabled or if this policy setting is not configured DNS clients use the default devolution level of two provided that DNS devolution is enabled.

Specifies the primary DNS suffix used by computers in DNS name registration and DNS name resolution. To use this policy setting click Enabled and enter the entire primary DNS suffix you want to assign. For example: microsoft. com. Important: In order for changes to this policy setting to be applied on computers that receive it you must restart Windows. If you enable this policy setting it supersedes the primary DNS suffix configured in the DNS Suffix and NetBIOS Computer Name dialog box using the System control panel. You can use this policy setting to prevent users including local administrators from changing the primary DNS suffix. If you disable this policy setting or if you do not configure this policy setting each computer uses its local primary DNS suffix which is usually the DNS name of Active Directory domain to which it is joined.

This policy setting extends the disk quota policies in this folder to NTFS file system volumes on removable media. If you disable or do not configure this policy setting the disk quota policies established in this folder apply to fixed-media NTFS volumes only. Note: When this policy setting is applied the computer will apply the disk quota to both fixed and removable media.

This policy setting determines whether the system records an event in the Application log when users reach their disk quota warning level on a volume. If you enable this policy setting the system records an event. If you disable this policy setting no event is recorded. When you enable or disable this policy setting the system disables the corresponding “Log event when a user exceeds their warning level” option on the Quota tab so that administrators cannot change logging while a policy setting is in effect. If you do not configure this policy setting no event is recorded but administrators can use the Quota tab option to change the logging setting. This policy setting does not affect the Quota Entries window on the Quota tab. Even without the logged event users can detect that they have reached their warning level because their status in the Quota Entries window changes. Note: To find the logging option in My Computer right-click the name of an NTFS file system volume click Properties and then click the Quota tab.

This policy setting determines whether the system records an event in the local Application log when users reach their disk quota limit on a volume and prevents users from changing the logging setting. If you enable this policy setting the system records an event when the user reaches their limit. If you disable this policy setting no event is recorded. Also when you enable or disable this policy setting the system disables the “Log event when a user exceeds their quota limit” option on the Quota tab so administrators cannot change the setting while a setting is in effect. If you do not configure this policy setting no events are recorded but administrators can use the Quota tab option to change the setting. This policy setting is independent of the enforcement policy settings for disk quotas. As a result you can direct the system to log an event regardless of whether or not you choose to enforce the disk quota limit. Also this policy setting does not affect the Quota Entries window on the Quota tab. Even without the logged event users can detect that they have reached their limit because their status in the Quota Entries window changes. Note: To find the logging option in My Computer right-click the name of an NTFS file system volume click Properties and then click the Quota tab.

This policy setting specifies the default disk quota limit and warning level for new users of the volume. This policy setting determines how much disk space can be used by each user on each of the NTFS file system volumes on a computer. It also specifies the warning level the point at which the user’s status in the Quota Entries window changes to indicate that the user is approaching the disk quota limit. This setting overrides new users’ settings for the disk quota limit and warning level on their volumes and it disables the corresponding options in the “Select the default quota limit for new users of this volume” section on the Quota tab. This policy setting applies to all new users as soon as they write to the volume. It does not affect disk quota limits for current users or affect customized limits and warning levels set for particular users (on the Quota tab in Volume Properties). If you disable or do not configure this policy setting the disk space available to users is not limited. The disk quota management feature uses the physical space on each volume as its quota limit and warning level. When you select a limit remember that the same limit applies to all users on all volumes regardless of actual volume size. Be sure to set the limit and warning level so that it is reasonable for the range of volumes in the group. This policy setting is effective only when disk quota management is enabled on the volume. Also if disk quotas are not enforced users can exceed the quota limit you set. When users reach the quota limit their status in the Quota Entries window changes but users can continue to write to the volume.

This policy setting determines whether disk quota limits are enforced and prevents users from changing the setting. If you enable this policy setting disk quota limits are enforced. If you disable this policy setting disk quota limits are not enforced. When you enable or disable this policy setting the system disables the “Deny disk space to users exceeding quota limit” option on the Quota tab so administrators cannot make changes while the setting is in effect. If you do not configure this policy setting the disk quota limit is not enforced by default but administrators can change the setting. Enforcement is optional. When users reach an enforced disk quota limit the system responds as though the physical space on the volume were exhausted. When users reach an unenforced limit their status in the Quota Entries window changes but they can continue to write to the volume as long as physical space is available. Note: This policy setting overrides user settings that enable or disable quota enforcement on their volumes. Note: To specify a disk quota limit use the “Default quota limit and warning level” policy setting. Otherwise the system uses the physical space on the volume as the quota limit.

This policy setting turns on and turns off disk quota management on all NTFS volumes of the computer and prevents users from changing the setting. If you enable this policy setting disk quota management is turned on and users cannot turn it off. If you disable the policy setting disk quota management is turned off and users cannot turn it on. If this policy setting is not configured disk quota management is turned off by default but administrators can turn it on. To prevent users from changing the setting while a setting is in effect the system disables the “Enable quota management” option on the Quota tab of NTFS volumes. Note: This policy setting turns on disk quota management but does not establish or enforce a particular disk quota limit. To specify a disk quota limit use the “Default quota limit and warning level” policy setting. Otherwise the system uses the physical space on the volume as the quota limit. Note: To turn on or turn off disk quota management without specifying a setting in My Computer right-click the name of an NTFS volume click Properties click the Quota tab and then click “Enable quota management. “
