MODEM OR CONFIG PROBLEM

GOING NUTS

I am having a headache with my connection. I have a DSL
networked with two others computers in another room. All
of a sudden, the computer which has the main connection
stopped working. I mean, I can't get online. On the other
hand, the two other computer get online, either through
the network or by itself thru the modem. I already did
everything I know: restore, checked the modem, switched
the network card, use the diagnostic lights(DELL option),
SFC, delete cookies history , lower the security
settings , changed wires, took the HUB off and disconected
the other ones and tried to connect the computer itself
and so on. And NOTHING seems to work. My technical support
says that the problem is the configuration because the
modem is not being able to communicate with the computer
and that I should call a technician or use the recovery CD.
By the way, I am using a DELL OPTIPLEX GX260 with XP
professional.
Any help would be very much appreciated.
Thanks!

Just to simplify things at this point -
Let's have the DSL modem directly connected to the
computer that is having the problem.
By the way, we are talking about an Ethernet connection right?
Is this a PPPoE connection? Meaning you have to make the
connection with a Username and Password?
Is the connection set to obtain an IP Address Automatically?
DNS set to Automatic also?
Is there a third party firewall being used and is it enabled?
Is there an Anti Virus program being used and is it kept up to date and enabled?
Do you have all of the XP critical updates installed?
What happens if you try to Repair the DSL connection in Network Connections?
What happens if you open the Command Prompt window and run the ipconfig /all command?
What IP Address do you get? Is it an APIPA in the 169.254.x.x range?
What happens if you then immediately run the ipconfig /renew command?
Do you get an error saying that an operation was attempted on
something that is not a socket? Or do you get some other error?
If you get the "something is not a socket" error, then you have damaged winsock keys in the registry.
If you get a different error then something else is going on.

If it is the winsock keys in the registry then -

Please read this whole reply before proceeding with any suggestions.

You should check System Information (winmsd)
START > RUN - type in winmsd and click OK
Expand Components / Network / click on Protocol -
if the section headings item of "Name" have a value
starting with anything other than MSAFD or RSVP
then that is probably what is causing the problem.

Examples:

MSAFD Tcpip [TCP/IP]
MSAFD Tcpip [UDP/IP]
RSVP UDP Service Provider
RSVP TCP Service Provider
MSAFD NetBIOS [\Device\NetBT_Tcpip...
and so on

It may be a third-party firewall or a Spyware or a Virus.
("New.Net" is a common spyware for example)
Make sure that MSCONFIG is in Normal Startup
and then see if uninstalling the third party firewall
(best done from its own uninstall program if available)
or the Spyware from Add Remove Programs will
resolve the issue. If it's a virus, then only an Anti Virus Program
will be able to deal with that.

You may want to try downloading either Ad-Aware 6 or Spybot
to another computer and then installing one of them on the infected XP Home/Pro
computer and try to wipe out Spyware and see if that resolves the issue.

Ad-aware 6.0 build 181

If none of that works or is possible, you could try this method
for replacing the winsock and winsock2 registry keys:

Uninstall any third-party proxy software or firewall programs before proceeding.

You maybe should consider enabling the XP ICF at least temporarily, especially
if you are not current with XP critical updates.

Step 1: Delete registry keys

A)Open Regedit from the Run line
B)Go to both of the following keys, EXPORT each of them, and then delete them:
(To export a key, you right click on it and choose "export" - you can choose where to export them to -
DESKTOP is handy -
and you need to type in a file name such as "exported Winsock key" / "exported WinSock2 key"
and then click on SAVE)

HKLM\SYSTEM\CurrentControlSet\Services\Winsock
HKLM\SYSTEM\CurrentControlSet\Services\WinSock2
C)Restart the computer

NOTE: It is important to restart the computer after deleting the Winsock keys.
Doing so causes the XP operating system to recreate shell entries for those two
keys. If this is not done, the next step does not work correctly.

Step 2: Install TCP/IP on top of itself

A)Open the properties window of the network connection (Local Area Connection)
B)Click Install
C)Click Protocol, then Add
D)Click Have Disk
E)Type the path to the \%systemroot%\inf folder (usually C:\Windows\inf) and click OK
(if you try to click Browse, then browse to the \inf folder,
it may not show up in the list)
F)You should now see "Internet Protocol (TCP/IP)" in the list of available
protocols. Select it and click OK.
G)Restart the computer

When the computer reboots you will have functional Winsock keys.
If so, then be sure to delete the exported winsock and winsock2 reg files.
(You don't want to accidentally put them back in the registry)

Side effects and possible problems:

This method will restore basic functionality to the Winsock keys, but is not a
complete rebuild. On a default install of Windows XP the registry key:
HKLM\SYSTEM\CurrentControlSet\Services\Winsock2\
Parameters\Protocol_Catalog9\Catalog_Entries will have 11 sub-keys.
When applying this method, the Catalog_Entries will only have 3 sub-keys.
However, it works and there does not appear to be any side effects.
The missing entries relate back to the:
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces key.
Also, third-party proxy software or firewalls may need to be reinstalled.

HI!
I REALLY APPRECIATED YOU DETAILED REPLY , AND I HOPE YOU
DON'T MIND MY ASKING AGAIN.
I DID FOLLOW THROUGH ALL THE STEPS YOU SUGGESTED, AND I
STILL GET NO CONNECTION IN MY MAIN COMPUTER, ONLY IN THE
NETWORKED ONES. MY TECHNICAL SUPPORT DOES NOT HELP AT ALL
AND I AM QUITE LOST AT THIS POINT.
ANSWERING YOUR QUESTION ON YOUR REPLY:
YES, I DO HAVE AN PPPoE CONNECTION, IT DOES CONNECT
THROUGH AN USER NAME AND PASSWORD, WHICH ARE SET
AUTOMACTLY. THE IP ADDRESS AND DNS ARE ALSO SET
AUTOMACTLY . I DO NOT HAVE A THIRD PART FIREWALL ENABLE,
THE ONLY ONE IS THE XP ICF, NOR AN ANTI-VIRUS ACTIVE. I
ALSO HAVE ALL THE MICROSOFT UPDATES UP TO THE DAY IT
STOPPED WORKING, LAST WEEK. IF I RUN IPCONFIG/ALL I DO GET
AN IP ADDRESS, HOWEVER THE LAST LINE : DEFAULT GATEWAY IS
BLANK AND BECAUSE OF THAT MY TECHNICAL SUPPORT SAID THAT
THE MODEM IS NOT BEING ABLE TO COMMUNICATE WITH THE
COMPUTER( SO IT'S MY COMPUTER THE ONE TO BLAME, NOT THEIR
SERVICE OR MODEM). ONCE IN A WHILE I DO NOT GET A IP
ADDRESS AT ALL WHEN I RUN IPCONFIG, ALL IT COMES ARE
ZEROS, AND IF I RUN IT AGAIN, IT COMES THE IP ADDRESS.
ONCE I RUN IPCONFIG/RENEW I ALWAYS GET THIS MESSAGE: AN
ERROR OCCURRED WHILE RENEWING INTERFACE LOCAL AREA
CONNECTION: UNABLE TO CONTACT YOUR DHCP SERVER.. REQUEST
HAS TIMED OUT. NEVER RENEWS I GUESS, BECAUSE THE MESSAGE
IS ALWAYS THAT.
SO, NOT KNOWING TOO MUCH WHAT'S GOING ON, I FOLLOWED ALL
THE STEPS YOU ADVISED ME. I DID INSTALL THE SPYBOT AND
CLEANED UP THE JUNK, REPLACE THE WINSOCK KEYS EVEN THOUGH
I WASN'T SURE IF IT WAS NECESSARY . AFTER I INSTALLED
TCP/IP ON TOP OF ITSELF. AND AGAIN NOTHING CHANGED. IT
STILL DOES NOT CONNECT ONLINE. IT'S HARD TO BELIEVE THAT
MY COMPUTER HAS ANY HARDWARE PROBLEM, SINCE IT'S NEW,
THREE MONTHS OLD(DELL OPTIPLEX GX260, PENTIUM 4), AND I
ALSO TRIED REPLACE THE NETWORK CARD TO SEE IF THE PROBLEM
WAS THAT AND STILL DID NOT CONNECT . I BELIEVE IF I
REINSTALLED THE XP NOTHING WILL CHANGE, SINCE I DON'T GET
ANY VISIBLE ERROR AND I CORRECTED EVERYTHING THAT MIGHT BE
GETTING ON THE WAY.

ANYWAY, I WOULD REALLY APPRECIATE IF YOU COULD THINK OF
ANYTHING ELSE THAT MIGHT BE GOING ON WITH MY CONNECTION.

=================================================
That winsock fix was only meant to be run if the error message was
"an operation was attempted on something that is not a socket"
No big deal though.
The error: "Unable to contact your dhcp server"
does in fact indicate that the computer is not making the connection
to the DSL modem.
You say you have already replaced the Ethernet Network Interface Card.
The next most likely suspect is the Ethernet cable.
I would try replacing that.
The next most likely suspect would be the DSL modem.
HTH
By the way, posting in all Capital Letters is considered shouting and rude.
I know you did not intend to be so.
=================================================
 
Hey XPUser -

Your post in this thread just saved my day! Thanks for sharing your expertise!

Again, THANK YOU! (Shouting due to excitement, not rudeness) ;-)
