As we see in the screenshot there is one user logged into this computer, the Administrator account. If you want to check multiple computers just create a list in notepad and save it as a batch file to run. This clearly won't work for a large quantity of servers, but it worked great for the 6 servers I needed to check. Unfortunately if the user does not have the appropriate permissions on the server they will not get an error message. Instead the result will list no sessions.
