Group Policy : Group Policy
refresh interval for users
At least
Microsoft Windows 2000
Specifies how
often Group Policy for users is updated while the computer is in use (in the
background). This setting specifies a background update rate only for the Group
Policies in the User Configuration folder. In addition to background updates,
Group Policy for users is always updated when users log on. By default, user
Group Policy is updated in the background every 90 minutes, with a random
offset of 0 to 30 minutes. You can specify an update rate from 0 to 64,800
minutes (45 days). If you select 0 minutes, the computer tries to update user
Group Policy every 7 seconds. However, because updates might interfere with
users' work and increase network traffic, very short update intervals are not
appropriate for most installations. If you disable this setting, user Group
Policy is updated every 90 minutes (the default). To specify that Group Policy
for users should never be updated while the computer is in use, select the Turn
off background refresh of Group Policy setting. This setting also lets you
specify how much the actual update interval varies. 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 number
you type in the random time box sets the upper limit for the range of variance.
For example, if you type 30 minutes, the system selects a variance of 0 to 30
minutes. Typing a large number establishes a broad range and makes it less
likely that client requests overlap. However, updates might be delayed
significantly. Important: If the Turn off background refresh of Group Policy
setting is enabled, this setting is ignored. Note: This setting establishes the
update rate for user Group Policies. To set an update rate for computer Group
Policies, use the Group Policy refresh interval for computers setting (located
in Computer Configuration\Administrative Templates\System\Group Policy). 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 a
user can run, might interfere with tasks in progress.
