The problem could be with Zone Alarm if you use that. There is a lot of
discussion on ZoneAlarm web site. Uninstall this in add remove programs as a
temporary fix.

This is a known issue with Zone Alarm and the KB951748 update. Workaround
until Zone Alarm gets their act together with a fix:

1. Uninstall KB951748 - not a great idea
2. Lower Zone Alarm's protection to Medium - not even a good idea
3. Uninstall Zone Alarm and use something better. The built-in Windows
Firewall is adequate for most people.

I think #3 is the best solution, but that's up to you. For further help, go
to Zone Alarm's user forums for support with their software.

This is a known issue with Zone Alarm and the KB951748 update.

Update:

Here's a workaround from one of the users ("Oldsod") on the ZA forums:

*****
If the windows update changed the usual needed files for
networking/internet, then the ZA will not see the changes and continue to
use the previously known files and ignore the newer files. Even though the
file names and locations are still the same from before, now the file size
and checksums no longer match.

To solve this, just reset the ZA database and the ZA will be "fresh" as when
it was first installed:

# Boot your computer into the Safe Mode
# Navigate to the c:\windows\internet logs folder
# Delete the backup.rdb, iamdb.rdb, *.ldb and the tvDebug files in the
folder
# Clean the Recycle Bin
# Reboot into the normal mode
# ZA will be just like new with no previous settings or data

Once this is finished, reboot back into the normal mode and in the new
network found windows, set the new network to Trusted.
Then do this to ensure the ZA is setup properly:

Make sure your DNS and DHCP server IP's are in your Firewall's Trusted zone.
Finding DNS and DCHP servers, etc

1. Go to Run and type in command and hit 'ok', and in the command then type
in ipconfig /all then press the enter key. In the returned data list will
be a line DNS and DHCP Servers with the IP address(s) listed out to the
side. Make sure there is a space between the ipconfig and the /all, and the
font is the same (no capitals).
2. In ZA on your machine on the Firewall, open the Zones tab, click Add and
then select IP Address. Make sure the Zone is set to Trusted. Add the DNS
IP(s) .
3. Click OK and Apply. Then do the same for the DHCP server.
4. The localhost (127.0.0.1) must be listed as Trusted.
5. The Generic Host Process (svchost.exe) as seen in the Zone Alarm's
Program's list must have server rights for the Trusted Zone.
Plus it must have both Trusted and Internet Access.
*****

Or you could uninstall Zone Alarm and use something better since ZA has
gotten quite bloated and invasive over the years, regularly causing issues.
The Windows Firewall built into XP and Vista is adequate for most people.

Malke, thanks for the effort to reproduce this here. However, it does not
work for all users. There is more detailed conversation going on at
http://forums.zonealarm.org/zonelabs/board/message?board.id=win_za_msgs&message.id=18667

All in all, a major snafu from MS to not let firewall makers in on the plan.
SOME paranoid people might wonder about MS's efforts to takeover the
firewall market ....

Thanks for the additional information. Actually, I put the blame squarely on
Zone Alarm. This is a program which has gotten progressively more bloated
and invasive over the years. While I used it on Windows machines for a long
time, I haven't recommended it in many years. It has caused too many
issues.

YMMV.

Which is one of the reasons I got rid of it and installed Online Armor and
had no problems with the update whereas my husbands machine still running ZA
Pro did have the problem.

Tried that but still had problems so just got rid of Zone Alarm on his

I've just installed the new relevant ZoneAlarm version 7.0.483.000,
and the outstanding MIcrosoft updates.
Everything seems to be working ok so far. Thanks to ZoneAlarm for
their swift action.

I am a victim of the KB951748 problem. By the time it was narrowed down to
that instead of a passing connection or hardware problem, my ability to
access anything had been killed.

Probing through the Event Viewer/System file I found that either registry
entries are missing, dll's missing, or both.

How do I recover from this without having to do a complete renstall of XP
SP-3 which, with all of its necessary stuff, amounts to 20-30 hours of work.
That, on top of about 25 hours of troubleshooting the problem so far.

Is there any way to reinstall the networking software, either from the
recovery partition, a CD, or using a distributable copy of the necessary
software?

Dick T,
Do you use Zone Alarm? If yes, there is a conflict with that update and some
versions of ZA.

1. Either uninstall the Update from the Control Panel> Add/Remove Programs.
2. Or run the System Restore feature, from the Start Menu, through the Help
interface.

Once you get your internet working, go to the Zone Alarm website and read
the fix they offer. I believe you need to download and install a different
version of Zone Alarm on your PC.

I've done all that and more. Tried the new & improved ZA after a clean
uninstall: Didn't help. Took off ZA and all of its traces: No help. Didn't
begin looking through Events Viewer listings until I had run out of all
reasons for the problem. That's when I found indications of missing dll's or
registry entries or files (all listed as possibilities).

In retrospect I realize now that the problem began immediately after
downloading the Msft updates. Began with losing access to the modem, then
some blips in reaching the router.

That took me into the usual rundown of first checking access with another
computer (good), then suspecting cables, ethernet card, etc, etc. And, into
endless rounds of checking every detail of settings in every possible bit of
access software to see if anything got messed up by accident or otherwise:
All good. That took me from about noon on Thursday to near midnight.

Friday morning (about 4:30 a.m.) began again. And again on Saturday.

It was either late Thursday night or early Fri morning when I learned from
Msft & ZA sites of the nature of the problem. Have been trying every
possible way to avoid a reinstall of XP ever since - including pouring
through several massive (ie 1,200 pages plus) Msft books on XP and what goes
