XP network source switch questions

[bob urz]

I have a XP SP2 machine i use for internet with a cable modem. I
occasionally send Email through a dial up internet connection because
the email will not go through the cable internet provider.

Here is my question, how does XP know what connection to use?
if i dial up the dial up, the computer will use the dial up
for internet and not the cable modem and i can send my email.

I can disconnect the dial up, but then it seems to take awhile
to get the internet back through the cable modem connection
so how does XP know when and how long to switch between the connections?

The real question is why are you at SP2 level and not SP3

Who said it was SP2? the computers XP is fully up to date


and not even connected to the

Internet via a Router ?

That's risky to say the least.

Then why would you use DUN when you have cable Internet ?

To send email out of a separate account

For email only ? The cable

Internet can serve that purpose.

I have a dial up account i sometimes send email out of. I can receive
email from the dial up account through the cable ISP, but cannot send
it. being blocked on one end or the other.

but you really did not answer the question. how does XP switch between
two network connections for internet?

Assuming your Cable Connection is always on but your Dialup connection
is on demand i.e. you only connect when you want to send an email.

If this is so then I suggest open your Internet Options by going to:

Tools >> Internet Connections >> Connections

Now select your dialup connection from the list and then select the last
radio button that says: "Always dial my default connection". See the
picture shown at this link:

He does that and everytime he performs something, like IE or Firefox, that wants to
connect to the Internet it will attempt a DUN connection.

As I understand it, he can't send any emails if he is connected to his
Cable Network. This could be a security issues because his email might
be with some other telco which does not allow relay of messages unless
you are logged in to their network. He therefore needs to tell his
system what to do in such circumstances.

Also, when he says he "I have a XP SP2 machine" he is simply saying that
his new machine was SP2 but it it must have been updated ever since.
One should always assume this because SP3 has been around for some time now.

We should wait for the OP to reply back.

Windows builds a routing table based on the last connection made. If you
make a dial-up connection after the cable connection, the routing table will
use the dial-up connection gateway as the path to the Internet. It has been
a while since I played with this, so I don't know the details of what
Windows does with the routing table when the dial-up connection is broken.
Could be that it does not immediately restore the cable modem routing table.

As for needing to use the dial-up connection to send email; the method you
are using is a kludge, and there should be a better way. Does your cable
provider block port 25 outbound? If so, does your dial-up provider allow
access to their mail server via a "Message Submission" port?

This is the information i am looking for. I did not know the process
used. Is there a specific microsoft name for this?

The systems works as i need it to. Yes, its Micky mouse. but i will live
with it. Its a secondary email i only occasionally use.
(different ISP than the cable modem)

My dial up is on manual so it will NOT auto dial without manual
intervention. As soon as the dial-up connects, the computer switches the
internet connection to it. I know this because the speed goes way down
and you can see the crt's flashing in the task bar. After i disconnect
from the dial-up, there seems to be some lag until i get internet back.
its seems like 30 seconds to 1 minute. It seems to me windows chooses
the most recent connection to use for interent

I am NOT trying to change this, Just understand whats going on under the
hood. I assume some port blocking by one of the isp's is causing
the cannot sent email issue.

One reason I would do it, I no longer have a reason, is you can use your
computer as a fax machine and *not* have to pay for internet fax service
or pay the UPS Store or someone else to send and receive faxes for you.

Fax does not equate DUN.

That's my bad, I certainly could have been clearer.

My intent was why would I have a connection other than cable or other
high speed connection.

I don't know of a specific name. And I don't have a way to test matters,
now. I fired my old ISP, which did allow me to maintain one ADSL connection,
and one dial-up connection simultaneously. I played with the 'route' command
at the command prompt. Learned how to manually modify the routing table with
the 'route add' command; such that I could actually ping my dial connection
from my DSL connection.

TTBMK, my new ISP does not permit simultaneous connections from two places.

Well, you have a choice: Either figure out how the Windows routing table is
managed, and how to manually override that management, or learn how to
manage your SMTP connections. In my experience, the latter is 10x easier.

I have an HP Photosmart All-In-One printer which can FAX with no dial-up
connection on the computer.

If I were to have a need again for faxes on a semi-regular basis, I'd
find a fax software program like WinFax 9 was. When you get an incoming
fax, you can have the incoming, as well as outgoing, faxes sorted into
folders just like an email client. And you can check each incoming fax
to see if you want it printed, so you don't waste paper and ink. You
also have electronic copies that you can work with, such as attaching
the fax to an email or document.

If you are receiving and sending too many faxes a day then clearly it
makes sense to invest in a dedicated fax machine or even "all-in-one
printer" that can do a wonderful job. It's crazy that in the 21st
century people are still sending faxes when a pdf file attached to an
email would do very well. I can't remember when .was it last time I
sent a fax to any of my business contacts!

Because there are many small businesses, say owner and maybe a single
employee, who don't use email as a means of doing business, and don't
have time to do if they wanted. They don't have secretaries and office
staff, and the owner actually goes out and works! LOL

David and Cheng,

With all due respect, I think there's a portion of the business
community you have no clue about, maybe don't know exists.

There are people who don't want the extra load of email and such, and
sometimes emails actually take more time that a simple phone call. Some
just don't understand computers.

A lot of these people also have to do their own shopping, I/O/W they
have to also go pick up the supplies they need. They have to return
calls from potential customers.

These are people for whom time spent in an office type environment,
doing that type of work, is lost time where the actual work cannot and
does not get done.

I always thought that Hotmail, Yahoo, AOL and Google have together made
sure every person on this planet has an email!

Not hardly. I know people who don't have email, and some that
maybe check theirs once a week. Of course, these are also people who
don't have a lot of their own personal info out there to be stolen.

To add to it, people
these days have facebook and twitter account (I accept I don't have
these two) and one needs an email account of some kind to open an
account.

A Facebook account with 0 actual facts in it, and no Twitter account at
all. I'm one of those that have far better things to do that deal with
either of those services.

What about on-line services like banking and tax filings?

I do on-line minimal banking, no online billpay, and taxes done by
someone else.

Surely, a business man (irrespective of size) must have some way of
communicating.

Telephone and face-to-face comes to mind.

Secretaries are a thing of the past.

Sometimes that is not a good thing. You can find yourself in a place
where the "big guy" who is getting paid $25/hr. doing the job of someone
who would be making $10/hr. Wouldn't it be better to be getting the
higher pay doing things to improve the business, bring in more business,
rather that take out the trash?

I don't have a
secretary and unlikely to have one. My GF is completely independent in
all respect and unlikely to help me in my business as my secretary. In
fact she is an Accountant so she makes sure I file my tax returns
correctly and on time.
