Event ID 1066 — Remote Desktop Session Host Listener Availability

Applies To: Windows Server 2008 R2

The listener component runs on the RD Session Host server and is responsible for listening for and accepting new Remote Desktop Protocol (RDP) client connections, thereby allowing users to establish new remote sessions on the RD Session Host server. There is a listener for each Remote Desktop Services connection that exists on the RD Session Host server. Connections can be created and configured by using the Remote Desktop Session Host Configuration tool.

Verify

To verify that the listener on the RD Session Host server is working properly, use any of the following methods.

Note:  RDP-TCP is the default connection name and 3389 is the default RDP port. Use the connection name and port number specific to your RD Session Host server configuration.

Method one

Use an RDP client, such as Remote Desktop Connection, to establish a remote connection to the RD Session Host server.

Method two

Use the qwinsta tool to view the listener status on the RD Session Host server.

To use the qwinsta tool:

  1. On the RD Session Host server, click Start, click Run, type cmd, and then click OK.
  2. At the command prompt, type qwinsta and then press ENTER.
  3. The RDP-TCP session state should be Listen.

Method three

Use the netstat tool to view the listener status on the RD Session Host server.

To use the netstat tool:

  1. On the RD Session Host server, click Start, click Run, type cmd, and then click OK.
  2. At the command prompt, type netstat -a and then press ENTER.
  3. The entry for 0.0.0.0:3389 (TCP port 3389) should be Listening.

Method four

Use the telnet tool to connect to the RDP port on the RD Session Host server.

To use the telnet tool:

  1. From another computer, click Start, click Run, type cmd, and then click OK.

  2. At the command prompt, type telnet servername 3389, where servername is the name of the RD Session Host server, and then press ENTER.

    If telnet is successful, you will receive the telnet screen and a cursor.

    If telnet is not successful, you will receive this error:

    Connecting To servername...Could not open connection to the host, on port 3389: Connect failed
