Log file on ICS connection on windows XP

I just setup a very simple LAN to share one dial-up line for all 50 computers which connected to our LAN. In this LAN, there is one enabled computer running Windows XP which has the ICS (internet connection sharing).

The question is, Is there such a log file that holds the record of activities perform by each client? I mean, what time they connected to www, where are they visiting etc?
