I just networked two computers that both have XP OS in
them in the house and every thing works fine. But now
for no reason one will dial-up the Internet by its self.
How do I stop this from happening again ? It never did
this before I networked them.

Could be a modem hijack. In which case you could end up owing $$$ to your local
phone company. Best check out the computer with the modem.

How current is your virus protection? Try these online virus scans first:
<http://security.symantec.com/ssc/home.asp>
<http://housecall.trendmicro.com/housecall/start_corp.asp>

Next, download LSP-Fix from <http://www.cexx.org/lspfix.htm>, and CWShredder
from <http://www.majorgeeks.com/download4086.html>.

First, run CWShredder.

Now check for, and remove, spyware. Get HijackThis
<http://www.majorgeeks.com/download.php?det=3155> and Spybot S&D
<http://security.kolla.de/index.php?lang=en&page=download>.
1) Install and run Spybot. First update it ("Search for updates"), then run a
scan ("Check for problems"). Trust Spybot, and make all recommended deletions.
2) Install and run HijackThis. Do NOT make any changes immediately. Save the
Log.
3) Have your HJT log interpreted by experts at one or more of the following
forums (and post it here):
<http://forums.tomcoyote.org/>
<http://www.wilderssecurity.com/>
<http://forums.net-integration.net/>
<http://www.spywareinfo.com/forums/>

If removal of any spyware affects your ability to access the internet (some
spyware builds itself into the network software, and its removal may damage your
network), run LSP-Fix.

Paranoia comes from experience - and is not necessarily a bad thing.
 
Without knowing how you networked your computers it is
difficult to say, however, I'd guess that one of three
things is causing your problem:
1) One (or perhaps both) of your computers is using
third-party software for dial-up Internet access, and
that software is configured to be an "always on"
connection, so it dials automatically.

2) One or both computers has Automatic Updates enabled,
so it automatically attempts to connect to the Internet.

3) Some other type of software is launching the autodial
feature.

For possible solutions, check the following, one at a
time:
1) Check to see if you can turn off autodial/always-on
features on the software that you use to access the
Internet.

2) If enabled, turn off Automatic Updates to see if that
corrects the problem.*

3) Investigate to see what other programs might have
features that automatically attempt to connect to the
Internet.

4) If you are using Internet Connection Sharing (ICS) to
network your computers, you can disable the ICS on-demand
dialing feature. Disabling ICS on-demand dialing should
prevent computers on your network from launching dial-up
connections without permission. To disable ICS on-demand
dialing:
a) Open Network Connections.
b) Right-Click the dial-up connection on which you want
to enable ICS on-demand dialing, and then
click "Properties."
c) On the "Advanced" tab, under "Internet Connection
Sharing," clear the check box titled "Establish a dial-
up connection whenever a computer on my network attempts
to access the Internet," to disable ICS on demand dialing.

* To find information about turning off Windows
Automatic Updates, click "Start," click "Help and
Support," and in the Search text box type "Automatic
Update," then press "Enter." When the search is complete,
click on "Full-text Search Matches," select the topic
titled, "Turn on automatic updates," and then follow the
instructions to turn off automatic updates. [ If you
elect to turn off Automatic updates, I would highly
recommend that you either setup a reoccurring reminder in
your calendar to "launch Windows Updates manually," or
schedule a task using Task Scheduler feature in Control
Panel to launch Windows Updates at regular intervals. ]

First, try shutting down all of your computers, then
restarting them. If you are using Internet Connection
Sharing (ICS), it is important that you restart the
computer on which ICS is enabled [it should be the only
computer on your network with a modem] before restarting
the others, as the ICS computer supplies the other
computers on the network with their configuration
information.

It would be helpful to know a little more about your
network. Are you using Internet Connection Sharing? How
are your computers networked? How many computers do you
have? Do you know which computer is trying to dial out?
If not, can you isolate which computer is causing the
problem by turning off one computer at a time, until the
problem stops [e.g. turn one off, if the problem
persists, turn it back on and then turn off the next
computer, etc.]? Are you running any other type of
software [such as antivirus software] on any of your
computers that might need to connect to the Internet for
updates?

I'm glad that I could help.

If you can ever track down the program that is causing
your computer to automatically attempt to dial, and
change the settings on that software to stop that
behavior [or remove the program if it is unwanted], then
you can re-enable the "On-demand dialing" feature of ICS
so that either of your computers will be able to launch
the Internet connection at will [if you want that
functionality].

For example, if both of your computers have dial-up
connections installed, some third-party Internet software
may attempt to automatically connect to the Internet.

With ICS enabled, both of your computers should be able
to connect to the Internet through the shared Internet
connection. ICS should only be enabled on one computer -
the one that directly connects to the Internet. The
computer with the shared Internet connection is called
the "ICS host" computer. All of the other computers on
the network are called ICS client computers. If both of
your computers had modems configured to connect to the
Internet before you networked them, then, on your *ICS
client computer* you should disable any connections
located under "Dial-up" in the "Network Connections"
folder -- !but only disable the Dial-up connections on
your ICS client computer! Instructions for disabling a
connection can be found in Help and Support. If there is
not an area in the Network Connections folder
labled "Dial-up," then you do not have a dial-up
connection configured on that computer, even if the
computer has a modem installed.

Remember that the "On-demand dialing" feature of ICS is
labled "Establish a dial-up connection whenever a
computer on my network attempts to access the Internet."
The actual Internet Connection Sharing feature is enable
or disabled using the check box labled "Allow other
network users to connect through this computer's Internet
connection." You can run ICS with or without the On-
demand dialing feature enabled.

Additionally, as noted by the other person who responded
to your post, a virus could be responsible for the
unwanted dialing behavior. I strongly recommend that you
run some type of antivirus software on all of your
computers. It is possible that some type of trogen
horse / virus is causing your computer to attempt to
dial. Antivirus software could detect and remove unwanted
virus programs. Information about antivirus software can
be found at www.microsoft.com by following the link
named "Protect your computer in 3 steps."

BTW - If you are not already using a third-party
firewall, be sure that Internet Connection Firewall [ICF]
is enabled on the Internet Connection of your ICS Host
computer. You can find information about ICF in Help and
Support.

Good luck.
