We have a windows based (windows 7 piece of software), and as part of the installtion process it is trying to register the software presumably with a 3rd party web server. but for whatever reason the registration is failing, and we assume its due to firewall rules at our permiter. My question is would there be any way/software/tool we could run on the actual PC that we are trying to install the software/register on, to get some clues to see what ports it is using to try and register the software with the external registration server? What "ports" are used for registering software as a general rule?

If I understand correctly you are looking for the port documentation of that particular software. If so, can you tell us what sw we are talking about or is it sensitive information?

it isnt well known software hence i wondered if you could sniff/capture what ports it was trying to send the registration details to to the remote registration server.

ah well in this case how about using wireshark;

above all else it prominently highlights errors like TCP packets resent (a likely thing to occur if there's a port problem).

Wow this is getting complicated. Effectively this is an "ethic hacker" that tries to crack some nuts. In this sense, maybe it's just normal for any firewall to block it; failing to do so would mean that scuba found something. That said, I recommend following that tech.support link in the bottom right corner: support@imperva.com

my understanding is this is merely registering the software, nothing to do with uploading the results or anything. i.e. it asks for contact name, email address (presuime so they can try and sell you their commercial software). its nothing to do with hacking.
