I'm running a small Active Directory domain (22 users) here in a wastewater treatment plant. I've been looking off and on for a means of telling who is logged in to the machines on my network. I haven't been able to find anything in either Windows 2000 server or Windows 2003 server that will give me this information. Is there a untility that will give this information? My preference would be for one that gives the username and computername, but even the IP of the computer would help since our dynamic addressing doesn't change all that much. Thanks.
