networked computerstarting dialing up

[Guest]

Hi
Hope this is not a repeat as my gateway computer just threw a wobbly.
I have two computers networked with dial up. The gateway computer has
internet sharing set up.
If the gateway in disconnected from the net. the second computer will
initiate dial up after a while. this could be a few minutes to hours.
I can solve this by turning off the sharing on the gateway, however I would
like to cure this another way.
Can I trace which program is initiating this connection, and can I trace
what address it is trying to connect to by dialing up.
Regards to all

On which OS? On XP Pro I would use netcap and format the resulting
..cap file with Ethereal.

Hi thanks for the reply

The first part is easy, I'm using XP Pro, as for the rest... netcap???? Cap
file????Ethereal????
Maybe we should wind this back a bit, I like the direction, just can't
understand the lingo ;-)

Robert is talking about the netcap.exe command line utility:

....and then using Ethereal to read the outputted log file:

Something on your second computer is trying to dial out, obviously. This is
usually a program that checks for updates occasionally - like an anti-virus
program, IE (if the option is checked on the Advanced options tab),
toolbars, or a myriad of other programs. It could also be malware/spyware
trying to "call home". It could be that you have automatic updates for
Windows turned on for that computer. Maybe a Favorite that is set to be
synchronized on a schedule?

You could also check your firewall log to see what's happening:
