Ethereal Capture-Filter for web address filtering?

Hello,

I guess this question must have been asked before but I haven't found 
any answers. My boss has told me to find out which web addresses within 
the company are surfed to when he is on holidays.

The network is handled by a w2k server. For the stations the server acts 
as gateway whereby it is forwarding internet traffic to a router which 
is connected to the dsl line. So every traffic passes the server. I 
installed Ethereal and played around a little bit. I already found out 
how to filter all traffic on port 80. But of course this only returns 
the data traffic between the two computers ip-addresses.

I guess I have to filter just the requests of the workstations to the 
dns server, haven't I? With this I could theoretically see which 
addresses are to be solved, am I right? How do I do this/which port do I 
filter for name resolution?

Thanks and best regards,

Felix Eggbert, Germany
