Configure the LCE (Undefined variable: LCE.WindowsClient)

If you did not configure the LCE (Undefined variable: LCE.WindowsClient) during installation, or if you want to modify the configuration, you can configure the client using the command line.


  1. Via the command line, go to the directory where you installed the LCE (Undefined variable: LCE.WindowsClient), and then execute the following command: server_assignment.exe --server-ip "<Server IP or Hostname>" --server-port <Server Port>

    • <Server IP or Hostname> corresponds to the IP address or hostname of the LCE server that you want the LCE Windows Client to communicate with. The hostname can be a maximum length of 46 characters.
    • <Port Number> corresponds to the port used to communicate with the LCE server. The default port is 31300.
  2. Type net stop "Tenable LCE Client"

    The Tenable LCE Client service stops.

  3. Type net start "Tenable LCE Client"

    The Tenable LCE Client service starts. The LCE (Undefined variable: LCE.WindowsClient) is configured.

Note: After the client is configured and authorized by the LCE server, a hidden file named. lcufh is created in C:\ProgramData\Tenable\LCE Client. This file contains a cache of process hashes and is used to store hashes that should only be reported once.
