I came across this post on stackoverflow about logging off users remotely & found it quite handy at times. Thus thought of making a note of it on my blog.
To check connected users on server, command is:
C:\Users\sarangb>qwinsta /server:<server-name> SESSIONNAME USERNAME ID STATE TYPE DEVICE services 0 Disc console 1 Conn rdp-tcp#3 user1 3 Active rdpwd user2 4 Disc rdp-tcp#0 user3 5 Active rdpwd rdp-tcp 65536 Listen
Note down the ID number from users you want to log off and then execute the following command:
C:\Users\sarangb>logoff 4 /server:<server-name>
If everything succeeded user with ID#4 should have been logged off.
