I recently installed the recovery disk for a firend with
Windows XP. He reconnected to his local ISP and was
working fine for about a week. He then tried to update
Windows XP to Service Pack 2. After he installed and
restared, he no longer can connect to the internet. He
called his ISP and they said it was a software problem. I
suggested he remove the updates which he did, but this
did not resolve the problem. Any help, Thanks in advance.

=============================================
Are we in fact talking about a Dial-Up Internet connection?
Or is it DSL or Cable? If so, is it an Ethernet connection?
XP Home or Pro?
What is the make and model of this system?
In System Properties, is the present version: 2002 Service Pack 1?
What EXACTLY happens when you try to connect to the Internet?
If you get an error message, what is it EXACTLY?
Is there an Anti Virus program installed? Which one?
Is there a third-party Firewall installed? Which one?
Is the XP Internet Connection Firewall enabled?
Has the system ever been scanned for Spyware?
==============================================
 
He could use system restore to go back to before he did
the updates. But I personally don't like doing this.

Think the spyware suggestion by XPUSER is the most
immediately promising thing he should try. Go to
www.safer-networking.org and download spy bot search and
destroy, get the updates and run it. I guess you'll have
to download it for him, download the updates programs and
then install it on his machine. I don't claim to
understand all this spy-ware stuff but it's a pain in the
arse and causes a lot of rubbish on our systems. Once
you have installed the main program on his machine, run
it up, and then close it. Then run the two update
programs, running it first just makes it easier as they
then have the installation directory to use.

He is connecting with a Cable modem via a NIC. The model
is a V2Premier 1.7 gig. (Their support sucks) Yes anti
virus Nortons, No third party firewall, XP home, has not
checked firewall enabled. No on scanned for spyware.
Don't know which, Installed updates once, then deleted
them.

Go to Control Panel | Network Connections -
Right click on the Connection for the cable modem
(probably LAC under LAN or High-Speed Internet)
and click on Properties | Advanced tab -
Put a check in the box to enable the XP ICF
and click OK and then highlight TCP/IP and click on
properties button - Set to "Obtain IP Address automatically"
and "Obtain DNS automatically" if not already set that way.
OK and close out back to Network Connections.
Right click on the cable modem connection and click on Repair
Do you get the error:
"Failed to renew the IP Address" ?
If yes -

Please read this whole reply before proceeding with any suggestions.

Issue:

on this XP Home/Pro computer,
when trying to browse the Internet,
you are getting "Page Cannot Be Displayed" and
when you go to the command prompt window
(Start > Run > cmd)
and run ipconfig /all, you get an APIPA in the form of 169.254.x.x.
Then immediately run ipconfig /renew, you get this error message:

"An operation was attempted on something that is not a socket"

or

"Unable to contact DHCP server"

If so, you probably have a damaged winsock2 key in the registry.

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
http://download.com.com/3000-2144-10214379.html?tag=list

Spybot - Search & Destroy 1.2
http://download.com.com/3000-2144-10194058.html?tag=list


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.

Step 1: Delete registry keys

A)Open Regedit from the Run line (Start > Run - regedit)

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

Go to Control Panel | Network Connections

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.
