How can I check if a user is logged on via Terminal Server?

A. Starting the Terminal Services Manager MMC snap-in (Start -Programs - Administrative Tools - Terminal Services Manager) will list userprocesses by machine but this may be cumbersome if a large number of terminalservers are running. It can also be done with the following command:

query user [] [/server:]

For example

C:> query user
USERNAME   SESSIONNAME     ID  STATE  IDLE TIME   LOGON TIME
>administrator  console    0   Active          . 09/05/9918:19
 savillj       rdp-tcp#1  1   Active         10 09/05/9914:23

The above lists all users.

You can also check what the user is running with the QPROCESS command:

C:> qprocess

To check who is running a certain program (e.g. winword.exe)

C:> qprocess

will list all users running the passed program.
