It is not possible to establish a Remote Desktop connection between the client
computer and the Headless server.
Ê Ensure if the Headless server is powered on.
Ê Check the network cable between the client computer and the Headless
server for proper connection.
Ê Ensure that the LAN activity LEDs on the Ethernet adapters of your client
computer and Headless server indicate a successful connection.
If your server boots into the operating system for the first time, ensure that
your Headless server is connected to your network through its onboard
Ethernet port 1.
Ê If the Remote Desktop connection failed while connecting to your Headless
server by its computer name, try establishing the connection by specifying
its IP address (if available).
Ê Ensure that the Remote Desktop connection is not blocked by local firewall
settings or a security suite on your client computer.
Ê Try to restart the Headless server by holding the On/Off button for one
second. The server will then shut down properly and the power LED will turn
off. Press the On/Off button again to reboot the Headless server and retry to
establish a Remote Desktop connection.
Ê If the server remains inaccessible, it might be necessary to recover the
operating system. Please proceed as described in section "Operating
system recovery" of the PRIMERGY TX100 S3 Core Edition Operating
Manual.
