Have the script write an INI file on a central server. Use the workstation name as the file name. Then write parameters as needed. Such as "user=fred", etc.
Then you can have a server process enumerate the directory; read the files it finds; send the e-mail; delete the file.
That seems to be my best solution, are there any examples here so I'm not re-inventing the wheel.
I'll need to to only run if domain user login OS is XP or Vista
