I have installed an IEEE 1394 PCMCIA card on my notebook
and the plug and play asks me to run the network wizard.
I have cancelled the wizard but changes are made to my
winsock so that I can't connect to my router and to the
web. If I do an IP config the IP has become fixed instead
of obtaining the IP from the router/firewall.
I can only temporary fix the problem by using a restore
point.
Any ideas?
========================================
You probably have damaged winsock keys in the registry.
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
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"
If so, you 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

Spybot - Search & Destroy 1.2

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
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.
If issue is resolved, then be sure to delete the exported Winsock / WinSock2
..reg keys
as you don't want to accidentally end up importing those damaged keys back
into the registry.
Also, be sure to visit the Windows Update site and make sure you have all
critical updates installed.
You also might consider turning off system restore and then turning it back
on
so as to remove previous restore points that would take you back to a
registry
with the damaged winsock keys. You could then create a restore point
manually
and let System Restore continue creating more restore points.
