If your View deployment includes a back-end firewall between your DMZ-
based security servers and your internal network, verify that the back-end
firewall allows traffic to port 9427 on your desktops.
Determine Whether to Use Windows Media MMR Based on Network Latency
Windows Media MMR adapts to network conditions by default on Windows 8 or later desktops. If the
network latency between Horizon Client and the remote desktop is 29 milliseconds or lower, the video is
redirected with Windows Media MMR. If the network latency is 30 milliseconds or higher, the video is not
redirected. Instead, it is rendered on the ESXi host and sent to the client over PCoIP.
Windows Media MMR adapts to network latency on Windows 8 or later desktops only. Users can run any
supported client system, Windows 7 or Windows 8/8.1.
This feature does not apply to Windows 7 desktops, where Windows Media MMR always performs
multimedia redirection, regardless of network latency.
You can override this feature on Windows 8 or later desktops, forcing Windows Media MMR to perform
multimedia redirection regardless of the network latency, by configuring the RedirectionPolicy registry
setting on the desktop.
Procedure
1 Start the Windows Registry Editor on the remote desktop.
2 Navigate to the Windows registry key that controls the redirection policy.
