4.1 Product Behavior
<1> Section 2.7.1.1: Except in Windows 2000 operating system, Windows XP operating system, and Windows Server 2003 operating system, when the network is unavailable, the Group Policy client also listens to network change notifications so that the policy can be refreshed as soon as the network is reachable. When a network change is detected and the Group Policy server is reachable, the policy application is applied only if the time elapsed is greater than the periodic refresh interval.
<2> Section 2.8.1: Periodic timer expiration for each user who is interactively logged on to the computer and for the computer itself is, by default, every 90 minutes, plus, by default, a random offset between 0 and 30 minutes. Windows Group Policy clients maintain separate timers for the computer and each user who is interactively logged on to the computer. Time-outs can vary from as low as 1 minute to any number of days. The timer interval is a value that is determined by the client computer configuration and is typically configured by an administrator.
