Our internet usage monitor (Win2k server, built in logging) usually lists usage under IP addresses, not user account names. I would like either one of the following:
1. Convince W2k server that it should log usernames instead of IP addresses - probably a really simple setting I've missed
2. A program which, given an IP address, returns the user logged on at that address ("currently" is sufficient as our IP addresses, although dynamic, rarely change).
