VDI Bandwidth Management via GPO policies

Last Updated:

Administrators can configure GPO policies to set the maximum bandwidth available for thin clients. Bandwidth restriction policies can also be implemented to apply specifically to office devices, allowing home users to take full advantage of personal network capabilities.

This article covers:


  • Administrator privileges
  • VDI setup

MSI bandwidth settings

Administrators configure these settings through the installer or registry (either HKCU or HKLM) using the keys/values below:

Key: \SOFTWARE\Policies\Zoom\Zoom Meetings\General

  • BandwidthLimitUp - Set the maximum sending bandwidth in kbps (has a minimum value of 800kb)
  • BandwidthLimitDown - Set the maximum receiving bandwidth in kbps (has minimum value of 800kb)
  • IgnoreBandwidthLimits - Ignore the web bandwidth

Web bandwidth settings

These are configured on the account page of the Zoom web portal and will override the MSI bandwidth settings unless IgnoreBandwidthLimits is set to 1. They can be applied based on IP address and rules. If no bandwidth limits exist or apply then the value can be set to 0.

Policy bandwidth settings

These registry keys are configured on the VDI client under SOFTWARE\Policies\Zoom\Zoom Meetings\VDI\bandwidth\ and work with thin clients to apply policies based on their .ini files*:

  • Office: These are the "on-premise" settings, which are determined by the .ini file for the thin client. On the thin client, check the .ini file in the install folder for the following line:
    If the value of IsInOffice is 1 that means that the office settings are used.
  • Home: If the .ini file does not exist, or the value of IsInOffice is 0, then the home settings are used.

Both values can accept three different connection types (ica, udp and direct) with "up" and "down" dword values configured for the bandwidth.

If the registry key "GPOBandwidthOverrideWeb=1" is configured, these values are used regardless of whether the value exists under the location and connection type. Since the default value is 0, there is no bandwidth limit if the value is not configured.

*Note: For Linux, which includes "eLux", the implementation is slightly different from the usual .ini file. Instead, an additional line is needed in a ZoomMedia.ini file located in this directory: setup/ica/ZoomMedia.ini

The additional line is the same:
