How to Install the Sun Ray Connector Windows Components
This procedure provides the steps to install the following SRWC components on the Windows system:
Multimedia redirection - Enhanced performance for Windows Media Player.
Adobe Flash acceleration - Enhanced playback capabilities for Adobe Flash content.
Sun Ray audio driver - Enhanced audio and video synchronization for multimedia content.
USB redirection - Enables access to USB devices connected to a Sun Ray DTU from a Windows session.
Audio input - Enables audio recording on a Sun Ray DTU from a Windows session.
Before You Begin
For information about how to install and configure SRSS 4.2 and SRWC 2.2, see the Sun Ray Server Software 4.2 and the Sun Ray
Connector for Windows OS Version 2.2 documentation.
If you want to install the Sun Ray Connector Windows components by using the *.msi files, you can use a 3rd-party tool to extract the
*.msi files from the srs-wininstaller.exe file.
Note
To bypass the installation UI, you can run srs-winstaller /S from the command line.
Steps
1. Log in to the Windows system as Administrator.
2. If you plan to install the USB Redirection component on a Virtual Machine (VM), you must add USB drivers on some VMs if they do not
provide drivers by default. See How to Add USB Drivers to a Virtual Machine for details.
3. The Windows system must have access to the SRWC image.
<SRWC_image>/srwc2.2/Sun_Ray_Connector_Windows_Components_1.0
4.
5.
6.
7.
Copy the srs-winstaller.exe file from the SRWC image to the Windows system.
Double-click the srs-winstaller icon to start the Sun Ray Connector Windows Components Setup Wizard.
Review the License Agreement and click I Agree.
Choose which components you want to install and click Install.

Multimedia Redirection - Next Steps
Additional Requirements for H.264 (MPEG-4)
The multimedia component does not include audio/video demux and decoders for H.264 (MPEG-4) streams. To ensure that MPEG-4 video
streams are accelerated properly, you need to download some third-party or freeware solutions.
Consider the following freeware:
MatroskaSplitter: http://haali.cs.msu.ru/mkv/
ffdshow: http://sourceforge.net/project/showfiles.php?group_id=173941
Alternatively, you can use a third-party codec, such as the SDK codec from MainConcept: http://www.mainconcept.com
For the MainConcept codec, the following items are required:
MPEG splitter
MPEG decoder
MP4 splitter
MP4 decoder
H.264 decoder
Many other solutions are possible. Not all solutions are listed here.
Xinerama Limitation
H.264 and VC-1 support on the DTU is not available for Xinerama sessions. In Xinerama sessions, video windows may be dragged from one DTU
to another or may span multiple DTUs. Audio/video synchronization of H.264 and VC-1 support is limited to the primary DTU, and the videos
cannot be synchronized between DTUs. H.264 and VC-1 videos may still be rendered by the application in the same manner as they would be
rendered on Sun Ray 1 DTUs.
7

For more information on Xinerama, see About Multihead Configurations.
Adobe Flash Acceleration - Next Steps
For Adobe Flash animations, users must enable "Third party browser extensions" in their browser's Internet Options.
Sun Ray Audio Driver - Next Steps
Caution
For audio to work properly, the Sun Ray audio driver must be set as the default. If users have changed their default audio
driver, they must perform the following procedure to make the Sun Ray audio driver the default.# From the Windows
Desktop, choose Settings->Control Panel.
1.
2.
3.
4.
Click Sounds & Audio Devices.
Click the Audio tab.
If the Sun Ray RDP Audio Driver is not the default, select it and click Apply.
Close your browser and reopen it.
USB Redirection - Next Steps
Under MyComputer, right-click Properties > Hardware > DeviceManager, the utSrSession under the System devices entry should be
displayed (Click image to enlarge).
See How to Verify that USB Redirection is Active for information about how to verify that USB redirection is working from a new session.
So deinstallieren Sie SRWC

Generically, a plastic card containing a microprocessor capable of making calculations. Smart cards that can be used to
initiate or connect to Sun Ray sessions contain identifiers such as the card type and ID. Smart card tokens may also be
registered in the Sun Ray Data Store, either by the Sun Ray administrator or, if the administrator chooses, by the user.
smart card token
An authentication token contained on a smart card. See token.
SNMP
Simple Network Management Protocol
spanning tree
An intelligent algorithm that enables bridges to map a redundant topology and eliminates packet looping in Local Area
Networks (LANs).
store-and-forward
switches
The switch reads and stores the entire incoming frame in a buffer, checks it for errors, reads and looks up the MAC
addresses, and then forwards the complete good frame out onto the outbound port.
subnet
A working scheme that divides a single logical network into smaller physical networks to simplify routing.
system
The Sun Ray system consists of Sun Ray DTUs, servers, server software and the physical networks that connect them.
T
TCP/IP
Transmission Control Protocol/Internet Protocol (TCP/IP) is a networking protocol that provides communication across
interconnected networks between computers with diverse hardware architectures and operating systems.
thin
client
Thin clients remotely access some resources of a computer server, such as compute power and large memory capacity. The Sun Ray
DTUs rely on the server for all computing power and storage.
tick
The time interval since a specific network event. It is defined as 1/100th of a second, which is the usual SNMP convention.
timeout
value
The maximum allowed time interval between communications from a DTU to the Authentication Manager.
token
The Sun Ray system requires each user to present a token, which the Authentication Manager uses to allow or deny access to the
system and to sessions. A token consists of a type and an ID. If the user uses a smart card, the smart card's type and ID are used as
the token. If the user is not using a smart card, the DTU's built-in type and ID (the unit's Ethernet, or MAC, address) are used
instead as a pseudo-token. If mobile sessions are enabled, a user can log in to an existing session from different locations without a
smart card, in which case the user name is associated with the session. A pseudo-token used for mobile sessions is called a mobile
token. Alias tokens can also be created to enable users to access the same session with more than one physical token.
token
reader
A Sun Ray DTU that is dedicated to reading smart cards and returning their identifiers, which can be associate with card owners
(users).
trusted
server
Servers in the same failover group that "trust" one another.
U
URI
Uniform Resource Identifier, the generic term for all types of names and addresses that refer to objects on the World Wide
Web.
user
session
A session that is running on a Sun Ray server and to which a user (identified by a smart card token or a pseudotoken) is logged
in.
V
VC-1
Informal name of the SMPTE 421M video codec standard, now a supported standard for Blu-ray Discs and Windows Media
Video 9.
virtual
desktop
A virtual machine containing a desktop instance that is executed and managed within the virtual desktop infrastructure,
usually a Windows XP or Vista desktop accessed through RDP.
virtual frame
buffer
A region of memory on the Sun Ray server that contains the current state of a user's display.

WMA
Windows Media Audio data compression file format and codec developed by Microsoft.
work group
A collection of associated users who exist in near proximity to one another. A set of Sun Ray DTUs that are connected to a Sun
Ray server provides computing services to a work group.
Windows
system
Throughout the SRWC documentation, "Windows system" indicates a Windows OS that can be accessed from a Sun Ray DTU
using SRWC. A Windows Terminal Server is one example of a Windows system.
Windows
Terminal
Server
A server running Windows Server software with Windows Terminal Services enabled.
Windows
Terminal
Service
A Microsoft Windows component that makes Windows applications and desktops accessible to remote users and clients.
Depending on the Windows release, this feature may be called Terminal Services, Remote Desktop Services, or Remote Desktop
Connection.
X

Description
Xnewt
The new default Xserver for Sun Ray Server Software 4.1 and later on Solaris.
Xserver
A process which controls a bitmap display device in an X window system. It performs operations on request from client applications.
Sun Ray Server Software contains two Xservers: Xsun, which was the default Xserver in previous versions of SRSS, and Xnewt, which
is the default Xserver for SRSS 4.1 and later. Xnewt enables the latest multimedia capabilities.
