A. Starting the Terminal Services Manager MMC snap-in (Start - Programs - Administrative Tools - Terminal Services Manager) will list user processes by machine but this may be cumbersome if a large number of terminal servers are running. It can also be done with the following command:
query user \[<user name>\] \[/server:<server name>\]
C:\> query user
USERNAME SESSIONNAME ID STATE IDLE TIME LOGON TIME
>administrator console 0 Active . 09/05/99 18:19
savillj rdp-tcp#1 1 Active 10 09/05/99 14:23
The above lists all users.
You can also check what the user is running with the QPROCESS command:
C:\> qprocess <user name>
To check who is running a certain program (e.g. winword.exe)
C:\> qprocess <process>
will list all users running the passed program.
