SQL SERVER 2000: obtain user list

Hi,
I would like extract in a document (.doc, .txt, .cvs, .xml or also) the
complete list of all user that logins to my SqlServer 2000.... that is
I need to know for each user to which databases accedes.

For example, the user TOM WHITE accedes to the database [SCHOOL],
[NEWS] and [JOB] with read/write permissions. I would like extract
these informations for all user and prints in a file to obtain a
complete documentation dinamically.

It's possible in SqlServer2000?
Thanks,
Luigi.

PS: sorry, but I don't write English very well.. :_(
