User tracking is supported with Active Directory. If you look at the UTLiteNT.bat file, you can modify it to reflect the AD domain name that the user account belongs to as well as the address/port of the CW2K server. We are currently using this across numerous Windows based systems including WinXP running SP2.
Once you have this script modified, you just need to call it from within the users logon script within AD. This will launch the utlite33.exe program and the username of the person logging in will be reported to CW2K.
You can find the two files (utliteNT.bat and utlite33.exe) that you need located in %NMSROOT%\campus\bin directory. Within the batch file is the location that you need to copy the files to.
