3389. All data received from Terminal Services on this port is forwarded to the server and all data
Terminal Services receives from the server is forwarded back to the socket. The iLO 2 firmware
reads anything received on this port as an RDP packet. RDP packets are exchanged between the
iLO 2 firmware and the server Terminal Services (RDP) server through the local host address on
the server. The service provided facilitates communications between the iLO 2 firmware and the
RDP server. The RDP server interprets the service as an established external RDP connection. For
more information on RDP services, see “Windows RDP Passthrough service” (page 35).
A Terminal Services session provides a performance-enhanced view of the host system console.
When the operating system is unavailable (or the Terminal Services server or client is unavailable),
the traditional iLO 2 Remote Console provides a view of the host system console. For more
information on Remote Console and Terminal Services, see “Remote Console and Terminal Services
clients” (page 37).
To configure the Terminal Services Passthrough option, see the “Terminal Services client
requirements” (page 35) and “Terminal Services Passthrough installation” (page 36).
Terminal Services client requirements
The Terminal Services client is available on Microsoft Windows client machines running:
• Windows Server 2003

The client is part of the operating system and is activated using Remote Desktop sharing. To
activate desktop sharing, select My Computer>Properties>Remote>Remote Desktop. The
Terminal Services client in Windows Server 2003 provides command-line options and seamless
launches from the Remote Console applet.
• Windows Server 2008
On Windows Server 2008 servers, the Terminal Services client and RDP connection is built-in.
The client is part of the operating system and is activated using Remote Desktop sharing. To
activate desktop sharing, select My Computer>Properties>Remote>Remote Desktop. The
Terminal Services client in Windows Server 2008 provides command-line options and seamless
launches from the Remote Console applet.
• Windows XP
On Windows XP servers, the Terminal Services client and RDP connection is built in. The client
is part of the operating system and is activated using Remote Desktop sharing. To activate
desktop sharing, select Start>Programs>Accessories>Communications>Remote Desktop. The
Terminal Services client in Windows XP provides command-line options and launches from
the remote console applet.
Windows RDP Passthrough service
To use the iLO 2 Terminal Services Passthrough feature, you must install a passthrough service on
the host system. This service displays the name of the iLO 2 Proxy in the host list of available
services. The service utilizes Microsoft .NET framework security and reliability. After the service is
started, the service polls iLO 2 to detect if an RDP connection with the client is established. If an
RDP connection with the client is established, the service establishes a TCP connection with local
host and begins exchanging packets. The port used to communicate with the local host is read
from the Windows registry at:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\
Wds\rdpwd\Tds\tcp\PortNumber
The port is typically port 3389.
