JSI Tip 3700. How can I limit the bandwidth that a computer or adapter uses in Windows 2000?

If you install the QoS Packet Scheduler (Psched.sys), you can limit the combined bandwidth reservations of all programs running on your Windows 2000 system by setting the NonBestEffortLimit value name, a REG_DWORD data type, to a percentage, between 0 and 100, of the total connection bandwidth. The default value is 20 percent.

The system wide setting is located at HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Psched. You can make adapter specific settings by using NonBestEffortLimit at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Psched\Parameters\Adapters\Adapter-GUID.

NOTE: Adapter specific settings take precedence.
