to track user logon/logoff


Step 1: Create the following two files using Notepad or your favorite text editor:

——logon.cmd—-
echo logon %username% %computername% %date% %time% >> \\sbs\share\logon.log

—–logoff.cmd—–
echo logoff %username% %computername% %date% %time% >> \\sbs\share\logon.log

Step 2: Update Group Policy to run the appropriate batch file. In Group Policy, go to:
User Configuration-> Windows Settings-> Scripts (Logon/Logoff)-> Logon

Step 3: As users log on and off, your log file should look something like this:

logon June VSXP Tue 22/02/2005 10:39:51.12
logoff June VSXP Tue 22/02/2005 10:41:08.45
logon MickM VSXP Tue 22/02/2005 10:42:01.07
logoff MickM VSXP Tue 22/02/2005 10:42:46.81
