Windows 2000 Domain Controllers refresh to other Windows 2000 Domain Controllers on
5 minute intervals. Non-DC Windows 2000 computers are
refreshed every
90 minutes.
If many WIndows 2000 computers requested a refresh at the same time, significant congestion would occur. To avoid this, a random offset interval is added to the refresh interval, to calclate the the refresh cycle. Windows 2000 domain controllers use a 0 minute offset, while non-DC Windows 2000 computers use 30 minutes. The refresh information for user and computer policies are maintained separately.
You can use the Group Policy to change these settings, or you can use the registry:
To change the refresh interval for computers: Registry key: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\System Value Name: GroupPolicyRefreshTime Data Type: REG_DWORD Range (in minutes): 0 to 64800 To change the offset interval for computers: Registry key: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\System Value Name: GroupPolicyRefreshTimeOffset Data Type: REG_DWORD Range (in minutes): 0 to 1440 To change the refresh interval for domain controllers: Registry key: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\System Value Name: GroupPolicyRefreshTimeDC Data Type: REG_DWORD Range (in minutes): 0 to 64800 To change the offset interval for domain controllers: Registry key: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\System Value Name: GroupPolicyRefreshTimeOffsetDC Data Type: REG_DWORD Range (in minutes): 0 to 1440 To change the refresh interval for users: Registry key: HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\System Value Name: GroupPolicyRefreshTime Data Type: REG_DWORD Range (in minutes): 0 to 64800 To change the offset interval for users: Registry key: HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\System Value Name: GroupPolicyRefreshTimeOffset Data Type: REG_DWORD Range (in minutes): 0 to 1440To immediately impose GPO settings upon a target workstation:
