Detailed dialup network connection logging?

The way I read it, he wants to know what his dial-up ISP uses for DNS
for its customers. That's going to be different from what he's using
because he has hardcoded the DNS entries on his host.

How hard would it be to find out? Just do NOT define a specific list of
DNS servers. Let the ISP specify the DNS server. Then do the nslookup
to see what his ISP gave him. That's how I find out what my ISP assigns
to me (because they have regional DNS servers).

I agree. I suggested that several days ago.

Actually, I'm not interested on the DNS I'm currently using. I only
interested on the DNS that is offered during a dialup connection.

Assume as I'm trying to re-get the gateway for my dialup connection directly
from my ISP, without reconnecting my dialup.

Exactly. Since the DNS are specifically set, Windows ignored the offered DNS
from the ISP. I need to be able to get the offered DNS from a log or
something, although it would be better if I could request them directly from
the ISP on demand.

Letting the ISP specify the DNS server (i.e.: use dynamic DNS on the dialup
connection setting) does give the exact answer I need, however I don't want
to use them. I need to use my custom list of DNS (as static DNS) while still
able to get that same ISP DNS.

Actually I'm the only respondent here that said to use 'nslookup' to
provide an on-demand means of testing which DNS server is currently
being employed for lookups. Maybe you suggested something else but I
don't see it in your replies here. You claimed 'ipconfig' wouldn't show
that info for dialup (I believe it will) so I don't know what you
thought you said would show the actual DNS server versus the configured
one.

Not applicable. If you don't configure the connectoid to use the ISP's
DHCP server to have it assign you a DNS server then you don't get one
from them. You just use the one that you specified.

- DHCP used for IP/DNS assignment:
You use what they give assign to you for IP address or DNS server.
ipconfig & nslookup show you what they assigned.

- DHCP *not* used, you specify the IP or DNS assignment (their static):
They never assign your IP address or DNS server. You told them not
to. You configured a static list of IP address or DNS server. You
use that. ipconfig & nslookup show you what you assigned.

If you don't override, you get their assignments. If you override, you
never get their assignment because you are *not* using their DHCP server
to get that assignment but instead you are using whatever you specified
as your override.

It is an exclusive disjunction operation: you get their assignment or
you use your own but there is no combination of both. It's "them XOR
you", not "them OR you". See http://en.wikipedia.org/wiki/Exclusive_or;
however, there is no 1-1 state as shown in the truth table in this
scenario. If you specify non-blank values, their DHCP server isn't
involved. They can't push an IP address or DNS server unless you use
their DHCP server, and you're not using their DHCP server.

What about the previous suggestion to (temporarily) remove your
hardcoded DNS entries and see what you get?

What I suggested the other day was for JJ to temporarily remove the
hardcoded DNS entries and let his dial-up ISP assign what they want
him to use. He could then make a note of those values and then make a
decision on whether or not to return to his hardcoded values.

I don't know of any other way to find the information he's looking
for.

Are you saying it's not good enough to get the ISP's DNS information
you're looking for, and then go back to your hardcoded DNS? If so,
there's something you're not telling us.

Oops, missed that. Once you got into ICS and routers in your reply, I
glanced over the rest since those didn't seem on target.

Agreed. Major tangent there, with the router/ICS stuff. Mostly my
fault.

Because I would need to dial it twice. You can't change a live dialup DNS
setting, since it's only in effect for the next conection session. Dialup is
different from LAN. LAN DNS can be changed on the fly and be applied
immediately.
