Dave,

I had this problem too.  I have a windows box that is connected to my 
little LAN and it was emanating a Windows "who-has" lookup about every 
15 minutes forcing a dial-up.  I discovered this by using tcpdump, e.g.
	tcpdump -vvv -i any

and comparing the output of this with the logs in /var/log/syslog which 
would record the time of any dial-up.

I posted this to debian-user, you can search the archives under the 
subject "finding network activity"
