Chapter 1
Most of the settings in this dialog box are pretty self-explanatory after you know where to find
them, but let’s take a quick tour. The Logon settings determine whether the connection is
enabled or disabled—if you disable ICA-TCP, then users cannot log onto an ICA session if
they’re using TCP/IP as their network protocol. The timeout settings determine how long an
active, disconnected, or idle connection has before the MetaFrame server terminates the
connection. The Security setting determines the encryption level used. The current ICA client
uses the RC5 encryption algorithm from RSA Data Security, supporting 40-bit, 56-bit, 128-bit,
and 128-bit logon-only security. The more encrypted the session, the more secure it is, but
greater encryption will impact performance, which is why using 128-bit security for dial-up
connections isn’t a good idea.
Disregard the online Help for Security, which will tell you that the Required Encryption setting
determines whether encryption is required for the connection and has either a Yes or No answer. This
functionality is an error.
Don’t edit the AutoLogon settings unless you want everyone who uses the selected connection to
log on using the same user account—these settings provide name, password, and domain
information for automatic logon. The Initial Program settings allow you to specify an application
to begin on startup. This application won’t be a published application; it will just be an
application running from the desktop. However, it will be the only application running on that
desktop, and if the user closes the application, the session will end. User Profile Overrides allows
you to prevent any user-chosen wallpaper from being used (which can help save on bandwidth).
Finally, at the bottom of this dialog box, you can specify what should be done when a connection
is broken: should the connection be disconnected or terminated, whether disconnected ICA
sessions should be allowed to reconnect from any machine or just from the one that initiated the
connection, whether shadowing is permitted, and whether the person whose session is being
monitored must explicitly permit that shadowing or whether they even have to be notified.
SpeedScreen Latency Reduction Manager
SpeedScreen Latency Reduction (SLR) describes two separate technologies: local text echo and
mouse click feedback. Local text echo accelerates the display of the input text on the client
device, which gives the user the feeling that there is no latency on the network. By default, this
feature of SLR is disabled for all applications and can be enabled for all or for individual
applications as needed. Mouse click feedback provides visual feedback for mouse clicks. When
the user clicks the mouse, the ICA Client immediately changes the mouse pointer to a pointer
that indicates that the user’s input is being processed in the background. When the mouse click
has been processed at the server, the client reverts the cursor to its previous form, indicating to
the user that the mouse click has been processed. This feature of SLR is enabled by default for
all applications and can be enabled for all or for individual applications as needed.
You’ll use the SLR Manager to turn on local text echo. Click this tool’s icon, and you’ll open a
list of all servers in the current farm. To enable SLR, click New and walk through the wizard to
choose an application. When you’ve finished, the application will appear in the list of
applications configured for SLR, as Figure 1.5 shows.
