NetPath endpoint port is closed

Updated December 8, 2016

Overview

The endpoint is red and in a critical status. When you click the endpoint to expand the issue, the message contains PercentPortClosed.

Environment

  • NPM 12.0 and later

Resolution

Step 1: Test TCP connectivity

  1. Download and extract PSTools.zip from Microsoft.
  2. Identify the IP address from the endpoint with the issue.
  3. Run psping from the command prompt to test end-to-end latency and packet loss to the NetPath service.

    psping -t endpoint_ip_address:endpoint_port

  4. After receiving 20 results, press Ctrl+C to stop.
  5. Look at the packet loss in the results. Check if it reads "Access is Denied" or if the packet loss less than 5%.

 

Did the TCP connectivity test successfully?

  • Yes: Go to Step 2.
  • No: The NetPath probe has an issue opening the port. Check the health of the endpoint server.

Step 2: Check the NetPath ConnectionBasedProbing flag

  1. Open C:\ProgramData\Solarwinds\Orion\NetPath\NetPathAgent.cfg.
  2. Check if the EnableConnectionBasedProbing flag is true.

Is the flag set to true?

  • Yes: Submit a ticket to technical support.
  • No: Follow this workaround:
    1. Open C:\ProgramData\Solarwinds\Orion\NetPath\NetPathAgent.cfg in a text editor as administrator.
    2. Save a copy of original NetPathAgent.cfg file as a backup.
    3. Stop the SolarWinds Job Engine 2 service.
    4. Change the following settings in the NetPathAgent.cfg file:

      "EnableConnectionBasedProbing", "true",

    5. Save the NetPathAgent.cfg file.
    6. Start the SolarWinds Job Engine 2 service.
