Sessions Tab
You
can use the Sessions tab to control session timeout settings for the
terminal server. Specifically, this tab enables you to choose timeout
settings for disconnected sessions, set time limits for active and idle
sessions, and define the behavior for disconnections and session limits.
By
default, these settings are defined not in this RDP-Tcp Properties
dialog box but in each user’s domain account properties. To override
these user-defined settings, you can click the Override User Settings
check box, as shown in Figure 5, and then choose options for the following policies:
End A Disconnected Session This setting determines when (if ever) a user is automatically logged off from a disconnected session.
Active Session Limit
This setting determines how long a user can stay active within a
Terminal Services session before automatically being disconnected.
Idle Session Limit This
setting determines how long a user can leave an inactive connection
open to a Terminal Services session before automatically being
disconnected.
When Session Limit Is Reached Or Connection Is Broken This setting determines whether a user is logged off automatically when a connection is broken (manually or automatically).
Environment Tab
This
tab enables you to control whether initial programs defined in a user’s
profile should be allowed to run automatically at the start of a
Terminal Services session. It also enables you to specify a program to
start for all users connecting to the local terminal server through RDP.
The Environment tab is shown in Figure 6.
Remote Control Tab
The
remote control feature of Terminal Services enables an administrator to
see or interact with another user’s Terminal Services session. By
default, the properties that define the behavior of this feature are
set on a per-user basis in each user account’s properties dialog box.
(These properties define how an administrator can view or control that
user’s Terminal Services sessions.) The Remote Control tab enables you
to control the settings of this feature on a per-server basis instead.
The
default settings of a user account enable an administrator to interact
with another user’s Terminal Services session only if the user provides
consent. However, you can use the Environment tab of the RDP-Tcp
Properties dialog box to enable administrators to interact with (or
merely to view) all user sessions with or without consent. You can also
prevent administrators from viewing or interacting with other users’
sessions completely.
Important: Remote Control works only from remote session
You
can use the Remote Control feature only from within an RDP session. If
an administrator is logged on to a terminal server locally, the feature
is disabled.
The Remote Control tab is shown in Figure 7.
Client Settings Tab
The Client Settings tab, shown in Figure 8, enables you to configure redirection of certain user interface features.
In
the Color Depth area of the tab, you can define the amount of color
detail sent from the Terminal Server to the client. The default setting
is 16 bits per pixel, but you can adjust this higher or lower. In
general, when you require more bit depth for RDP connections,
appearance is improved at the expense of performance.
In
the Redirection – Disable The Following area of the tab, you can
determine which features should not be redirected to the client. The
advantage of disabling redirection is improved performance, but this
improvement comes at the expense of the advantages offered by each
particular feature that you choose to disable.
Drive
When you select this option, the drives local to the client cannot be
included in the Terminal Services connection. (To include the drives,
this check box must be cleared, and the Drives option must be selected
on the Local Resources tab of the Remote Desktop Connection client.)
Windows Printer
When you select this option, printers local to the client cannot be
accessed in the Terminal Services connection. However, a user can still
connect to the client printer at the command prompt by using LPT port
mapping or COM port mapping.
LPT Port Selecting this option prevents users from mapping a connection to an LPT printer.
COM Port Selecting this option blocks a connection from the Terminal Services session to COM devices on the client computer.
Clipboard
This option, when selected, prevents users from cutting or copying data
from a Remote Desktop (Terminal Services) session and then pasting that
data into the local session on the client computer. Over slow
connections, disabling clipboard redirection can prevent screen freezes.
Audio
When enabled, this option prevents the transmission of audio data from
the remote desktop to the local client computer. This is the only
option that is selected by default.
Supported Plug and Play Devices
This option, when selected, prevents Plug and Play devices local to the
client from being redirected to a Terminal Services session.
Default to Main Client Printer
When you select this option, the default printer assigned to the
Terminal Services client is prevented from serving as the default
printer for the Terminal Services session.
Network Adapter Tab
This
tab enables you to restrict the default RDP-Tcp connection to listen
for RDP connection attempts on only one particular network adapter. The
tab also enables you to set a limit on the number of connections
allowed by the terminal server. By default, no limit is set, as shown
in Figure 9.
