TimerResolution

HKLM\SOFTWARE\Policies\Microsoft\Windows\Psched

Description

Determines the smallest unit of time that the Packet Scheduler uses when scheduling packets for transmission. The Packet Scheduler cannot schedule packets for transmission more frequently than permitted by the value of this entry.

This entry stores the setting of the Set timer resolution policy (Computer Configuration\Administrative Templates\Network\QoS Packet Scheduler). Group Policy adds this entry to the registry when you enable the Set timer resolution policy.

• If you enable this policy, Group Policy stores the value you specify in the policy in the value of this entry.
• If you disable this policy or do not configure it, Group Policy deletes this entry from the registry and uses the default timer resolution set for the system.

If you enter a value that is too small for the Hardware Abstraction Layer on your system to support, the system uses the smallest supported interval.

Change method

To change the value of this entry, use Group Policy. This entry corresponds to the Set timer resolution Group Policy (Computer Configuration\Administrative Templates\Network\QoS Packet Scheduler).

Note

This entry is not included in an Administrative Template (.adm) files provided with Windows 2000. To use this entry, you must write a policy and add it to a new or existing .adm file. For instructions, see Advanced topic: Creating custom .adm files in Windows 2000 Server Help.

This entry takes precedence over a user setting. When this entry appears in the registry, a policy is in effect and the system ignores the value of TimerResolution in the Psched\Parameters subkey.

Tip

For detailed information about particular Group Policy settings, see the Group Policy Reference (Gp.chm) on the Windows 2000 Resource Kit companion CD.

For general information about Group Policy, see Group Policy in Windows 2000 Help.
