Use the Bandwidth Throttler in Internet Server Manager to limit the bandwidth available to Internet Information Server. You can enable the Bandwidth Throttler from the property page for any of the three IIS services. The limit you set applies to the combined bandwidth used by all three IIS services, regardless of which property page you set it from.
Û To enable the Bandwidth Throttler
1. On the WWW Service Properties, FTP Service Properties, or Gopher Service Properties page, click the Advanced tab, then click Limit Network Use by all Internet Services on this computer.
2. In the Maximum Network use box, type the maximum amount of bandwidth you want the combined IIS services to use, in kilobytes per second.
You do not need to restart the server or the service to activate the Bandwidth Throttler. The Bandwidth Throttler is enabled dynamically. Because you do not need to restart the server, you can enable and disable the Bandwidth Throttler or change the value of Maximum Network use as needed. For example, you can restrict use of bandwidth by Internet Information Server during peak morning hours to make more bandwidth available for electronic mail.
Note
The value that you enter in the Maximum Network use box is stored in the BandwidthLevel value entry in the Registry. BandwidthLevel does not appear in the Registry until you enable the Bandwidth Throttler. If you later disable the Bandwidth Throttler, the value of BandwidthLevel is set to 0xFFFFFFFF.
You can enable the Bandwidth Throttler by adding the BandwidthLevel value entry to the Registry and setting BandwidthLevel to a value lower than 0xFFFFFFFF. However, if you edit the Registry, you must stop and restart the server to make the change effective.
For more information on BandwidthLevel, see Regentry.hlp, the Registry Help file, on the Supplement 1 CD.
Warning
To add or modify a Registry value entry, use administrative tools such as Control Panel or System Policy Editor whenever possible. Using a Registry editor (Regedit or Regedt32) to change a value can have unforeseen effects, including changes that can prevent you from starting your system.
