Configuring Remote Desktop Features

Table Of Contents
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 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.
The registry key that you configure 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.\VMware tsm
mr
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 effect.
Managing Access to Client Drive Redirection
When you deploy Horizon Client and Horizon Agent with client drive redirection, folders and files 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. If VMware Blast is enabled, files and folders
are transferred across a virtual channel with encryption.
TCP connections on port 9427 are required to support client drive redirection. If your Horizon 7
deployment includes a back-end firewall between your DMZ-based security servers and your internal
network, the back-end firewall must allow traffic to port 9427 on your remote desktops. If VMware Blast is
enabled, TCP port 9427 is not required to be open because client drive redirection transfers data through
the virtual channel.
The Client Drive Redirection custom setup option in the Horizon Agent installer is selected by default.
As a best practice, enable the Client Drive Redirection custom setup option only in remote desktops
where users require this feature.
