Determines how often Group Policy is applied to computers.
This entry stores the setting of the Group Policy refresh interval for computers Group Policy. Group Policy adds this entry to the registry when you configure the Group Policy refresh interval for computers policy.
This entry specifies a the upper limit to a random offset for how often Group Policy for computers is updated (in the background) while the computer is in use. This entry specifies a background update rate only for Group Policies in the User Configuration folder.
To prevent clients with the same update interval from requesting updates simultaneously, the system varies the update interval for each client by a random number of minutes. The value of this entry sets the upper limit for the range of variance. For example, if the value of this entry is 30 minutes, the system selects a variance of 0 to 30 minutes. A large number establishes a broad range and makes it less likely that client requests overlap. However, updates might be delayed significantly.
To change the value of this entry, use Group Policy. This entry corresponds to the Group Policy refresh interval for computers policy (User Configuration\Administrative Templates\System\Group Policy).
Note
If the DisableBkGndGroupPolicy entry is set to 1, this entry is ignored.
This entry establishes the update rate for User Group Policy. To set an update rate for user policies, use the GroupPolicyRefreshTimeOffset entry in HKLM.
Tip
Consider notifying users that their policy is updated periodically so that they recognize the signs of a policy update. When Group Policy is updated, the Windows desktop is refreshed; it flickers briefly and closes open menus. Also, restrictions imposed by Group Policies, such as those that limit the programs users can run, might interfere with tasks in progress.
To specify that Group Policy should never be updated while the computer is in use, enable the Disable background refresh of Group Policy policy.
For detailed information about particular Group Policy settings, see the Group Policy Reference (Gp.chm) on the Windows 2000 Resource Kit companion CD.
