RDP Compression Algorithm

Among the various Group Policy settings you can configure for Remote Desktop Services, there is one particular setting which allows you to disable compression for RDP traffic. In certain network environments where compression is handled by third-party devices, double compression can sometimes cause problems to your remote session environment.

Through the Set compression algorithm for RDP data policy setting, you can specify which RDP compression algorithm to use or to disable compression completely. Not to use an RDP compression algorithm is only recommended if you are using a hardware device that is designed to optimize network traffic. The other options include an algorithm that is optimized to use less memory, this option is less memory-intensive, but uses more network bandwidth. The algorithm that is optimized to use less network bandwidth uses less network bandwidth, but is more memory-intensive. Additionally, a third option is available that balances memory usage and network bandwidth.

  1. To configure this policy, open the Local Group Policy Editor snap-in by typing gpedit.msc in the Start search text box and press enter.
  2. Go to Local Computer Policy\ Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Remote Session Environment node.
  3. Double click Set compression algorithm for RDP data and check the Enabled radio button.
  4. Under RDP compression algorithm, choose the desired option from the drop-down list of functions
  5. Click Apply and OK.

Note, that when choosing not to use an RDP compression algorithm, some graphics data will still be compressed.
