You can use "net sessions" or use Computer Management/shared folders/sessions. For IP
addresses on the lan you may need to ping computer name or look at dhcp leases/wins
database/dns zone records. For outside of the lan you would need to correlate your
firewall logs to find the IP address or use a personal firewall on the computer and
review the firewall log. Sygate has good logging capability and is free to try. You
also want to enable auditing of logon events on your server and look in the security
log in Event Viewer to se what users have connected to the server. --- Steve
