Configuring Remote Desktop Features

Horizon policies
In Horizon Administrator, set the Multimedia redirection (MMR) policy to
Allow. The default value is Deny.
Back-end firewall
If your Horizon 7 deployment includes a back-end rewall between your
DMZ-based security servers and your internal network, verify that the back-
end rewall allows trac to port 9427 on your desktops.
Determine Whether to Use Windows Media MMR Based on Network Latency
By default, Windows Media MMR adapts to network conditions on single-user desktops that run on
Windows 8 or later and RDS desktops that run on Windows Server 2012 or 2012 R2 or later. 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.
This feature applies to Windows 8 or later single-user desktops and Windows Server 2012 or 2012 R2 or later
RDS desktops. Users can run any supported client system, Windows 7 or Windows 8/8.1.
This feature does not apply to Windows 7 single-user desktops or Windows Server 2008 R2 RDS desktops.
On these guest operating systems, Windows Media MMR always performs multimedia redirection,
regardless of network latency.
You can override this feature, forcing Windows Media MMR to perform multimedia redirection regardless
of the network latency, by conguring the RedirectionPolicy registry seing 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.
The registry key that you congure for a remote desktop depends on the bit version of the Windows
Media Player.
Option Description
64-bit Windows Media Player
n
For a 64-bit desktop, use the registry key:
HKEY_LOCAL_MACHINE\Software\VMware,Inc.\VMware tsmmr
32-bit Windows Media Player
n
For a 32-bit desktop, use the registry key:
HKEY_LOCAL_MACHINE\Software\VMware,Inc.\VMware tsmmr
n
For a 64-bit desktop, use the registry key:
HKEY_LOCAL_MACHINE\Software\Wow6432Node\VMware,Inc.\VMwa
re tsmmr
3 Set the RedirectionPolicy value to always.
Value name = RedirectionPolicy
Value Type = REG_SZ
Value data = always
4 Restart Windows Media Player on the desktop to allow the updated value to take eect.
Managing Access to Client Drive Redirection
When you deploy Horizon Client 3.5 or later and View Agent 6.2 or later or Horizon Agent 7.0 or later with
client drive redirection, folders and les are sent across the network with encryption. Client drive
redirection connections between clients and the View Secure Gateway and connections from the View
Secure Gateway to desktop machines are secure.
For Horizon Client 4.2 or Horizon 7 version 7.0.2 or later, if VMware Blast Extreme is enabled, les and
folders are transferred across a virtual channel with encryption.
