  Dear All,
  
  When I open workbench, I encounter this error "Could not connect to any license server. The server is down or is not responsive". I have stable internet connection and am using Ansys 17.2 version. I can't find the modules on the left bar as well. Thank you for your help in advance.

  Hi Alireza,
  Can you please try to ping and telnet the server first, please send the screenshot of same..
  Go to the start menu and open the command prompt, and run the commands and send the screenshot of output:
  - ping servername
  - telnet servername portnumber (bydefault port number is 1055.)
  A blank screen will confirm that you are connected, if you get any other output, please provide a screenshot of the same.
  - To ON telnet service go to start àsearch “Turn Windows feature on or off” àcheck box “Telnet Client” and click ok.
