Configuring iLO 2 37
Enabling the Terminal Services Passthrough option
By default, the Terminal Services Passthrough feature is disabled and can be enabled on the
Administration>Access>Services page. The Terminal Services button in the Remote Console is deactivated
until the Terminal Services Pass-Through feature is enabled.
To use of the Terminal Services Passthrough feature, install the latest Lights-Out Management Interface
Driver and then install Terminal Services passthrough service for Microsoft® Windows® on the server.
When the Terminal Services Passthrough option is set to Enabled or Automatic on the
Administration>Access>Services page and the Terminal Services Client is installed on the Windows®
client (installs by default on Windows® XP), the Terminal Services button is enabled. When you click the
Terminal Services button, the applet tries to launch the Terminal Services, even if the server is not running
a Windows® operating system.
You must comply with Microsoft® license requirements which are the same as connecting through the
server's NIC. For instance, when set for administrative access, Terminal Services does not allow more
than two connections, regardless of whether the connections are through the server's NIC, or iLO 2, or
both.
Terminal Services warning message
Terminals Services users operating on Windows® 2003 Server might notice the following when using the
Terminal Services pass-through feature of iLO 2. If a Terminal Services session is established through iLO
2 and a second Terminal Services session is established by a Windows® administrator (Console mode),
the first Terminal Services session is disconnected. However, the first Terminal Services session does not
receive the warning message indicating the disconnection until approximately one minute later. During
this one-minute period, the first Terminal Services session is available or active. This is normal behavior,
but it is different than the behavior observed when both Terminal Services sessions are established by
Windows® administrators. In that case, the warning message is received by the first Terminal Services
session immediately.
Terminal Services Passthrough option display
The iLO 2 firmware might not accurately display the Terminal Services Passthrough option. The Terminal
Services Passthrough option might appear active even if the operating system is not Terminal Services
enabled (for example, if the host operating system is Linux, which does not support Terminal Services
operation).
Remote Console and Terminal Services clients
Using the management network connection to the iLO 2, an iLO 2 Remote Console session can be used to
display a Terminal Services session to the host. When the iLO 2 Remote Console applet runs, it launches
the Terminal Services client based on user preference. The Sun JVM must be installed to obtain full
functionality of this feature. If the Sun JVM is not installed, then the Remote Console cannot automatically
launch the Terminal Services client.
If Terminal Services pass-through is enabled, and the Terminal Services server is available, switching
between iLO 2 Remote Console and the Terminal Services client will be seamless as the server progresses
from pre-operating system environment to operating system-running environment, to operating system-not
available environment. The seamless operation is available as long as the Terminal Services client is not
started before Remote Console is available. If Remote Console is available and the Terminal Services
client is available, Remote Console will start the Terminal Services client when appropriate.
