Evil-winrm program can be used on any Microsoft Windows Servers with this feature enabled (usually at port 5985), of course only if you have credentials and permissions to use it. So we can say that it could be used in a post-exploitation hacking/pentesting phase. The purpose of this program is to provide nice and easy-to-use features for hacking. It can be used with legitimate purposes by system administrators as well but most of its features are focused on hacking/pentesting stuff.
TroubleshootingWinRM means checking to make sure the WinRM service is running, and firewall ports are open. You should also check the WinRMconfigurationand that the WinRM listener exists. Finally, check to ensure WinRM is able tocommunicate with WMI.
