Powershell Log Off Remote Session

Question

I am trying to formulate a Powershell command to remotely log off a user. We have a terminal server with a very unstable program that sometimes locks sessions. We have to re

Answer 1

Log off all users from a machine:

try {
   query user /server:$SERVER 2>&1 | select -skip 1 | foreach {
     logoff ($_ -split "\s+")[-6] /server:$SERVER
   }
}
catch {}

Details:

• the try/catch is used when there are no users are on the server, and the query returns an error. however, you could drop the 2>&1 part, and remove the try/catch if you don't mind seeing the error string
• select -skip 1 removes the header line
• the inner foreach logs off each user
• ($_ -split "\s+") splits the string to an array with just text items
• [-6] index gets session ID and is the 6th string counting from the reverse of the array, you need to do this because the query output will have either 8 or 9 elements depending if the users connected or disconnected from the terminal session
