Hi Karan! Take note that the letters inside brackets are parameters. Here is a guide to use this command:
And for testing connectivity, you must use netcat inside toolbox, as Telnet is not present in VA. You should type:
$tb start
$tb session
nc -zv -w 5 FQDN PORT
there, you have to replace FQDN with the full qualfied name of your AD or IQService server, and PORT should be 389 and 636 for AD, and 5050 and 5051 for IQService.
