Killed LAN connection

[Mark]

Installed on a Win 2000 PRO dual boot system with WIN 98SE
on the C:/ partition. MSAS scanned both partitions.
Numerous hits, mostly on the WIN98SE partition. Followed
recommended actions and while WIN 2000 PRO is running
fine, I can no longer connect to the Net through my
COMCAST/router setup in WIN98SE. Reinstalled NIC drivers
and all protocols. No effect. Net is dead.

Ideas?

Potential issue with network connectivity and Windows Firewall when removing
some programs that install a layered service provider
Some programs install layered service providers (LSPs) on computers to
gather data on your Web browsing and network activity. When you use Windows
AntiSpyware to help remove these programs, it also removes the LSPs. In some
cases Windows AntiSpyware does not properly restore the LSP configuration
data.



If this happens, you may find that your computer is unable to connect to the
Internet or your network. You may also see an error message stating that
Windows cannot start Windows Firewall service or the Internet Connection
Sharing (ICS) service.



To resolve this problem, you need to use Windows to rebuild the LSP
configuration data. The following steps apply if you are running Microsoft
Windows XP Service Pack 2 (SP2).



To use Windows to rebuild the LSP configuration data

1. Log on to your computer with an account that is part of the
Administrators group.
2. Open a command prompt window. To do this, click Start, click Run, type
cmd, and click OK.

3. At the command prompt, type netsh Winsock reset and press ENTER.
4. When the Winsock reset is finished, The command window shows the
following message:
Successfully reset the Winsock Catalog. You must restart the machine in
order to complete the reset.
If you see this message, restart your machine.

If you are not logged in with an administrator group, you will receive the
following error message:
Unable to reset the Winsock Catalog. Access is denied.
If you receive this message, log off of your computer, and log on with an
account that is part of the Administrators group. Repeat steps 2-4.

5. After you restart your computer, see the KB article at
support.microsoft.com/?scid=kb;en-us;892350 for more information.

In some instances third-party applications can be affected while connecting
to the Internet or network after you follow these steps. If you notice that
third-party applications are not properly accessing the Internet or network,
you should reinstall the application to restore network functionality.

If you are running any other version of Microsoft Windows, see the KB
article at support.microsoft.com/?scid=kb;en-us;892350 for information about
how to resolve this problem.

Microsoft KB explaining the issue and giving fixes--easy for XPSP2, a little
harder for Windows 2000--you have to see a second KB article linked to this
one.
http://support.microsoft.com/kb/892350

On the older versions, this third-party utility may get the job done more
easily:

I didn't know there was a different approach for 2000 users, thanks Bill.

 

[Bill Sanderson]

The KB article is complete, and covers Windows 2000. However, the
third-party utilities are somewhat easier to use for many.

Hi Andre - From my Blog, Defending Your Machine, here:
http://defendingyourmachine.blogspot.com/

#########IMPORTANT#########
Before you try to remove spyware using any of the programs below, download
both a copy of LSPFIX here:
http://www.cexx.org/lspfix.htm

AND a copy of Winsockfix for W95, W98, and ME
http://www.tacktech.com/pub/winsockfix/WinsockFix.zip
Directions here: http://www.tacktech.com/display.cfm?ttid=257

or here for Win2k/XP
http://files.webattack.com/localdl834/WinsockxpFix.exe
Info and download here: http://www.spychecker.com/program/winsockxpfix.html
Directions here: http://www.iup.edu/house/resnet/winfix.shtm

The process of removing certain malware may kill your internet connection.
If this should occur, these programs, LSPFIX and WINSOCKFIX, will enable you
to regain your connection.

NOTE: It is reported that in XP SP2, the Run command

netsh winsock reset

will fix this problem without the need for these programs. (You can also try
this if you're on XP SP1. There has also been one, as yet unconfirmed,
report that this also works there.) Also, one MS technician suggested the
following sequence:

netsh int reset all
ipconfig /flushdns

See also: http://windowsxp.mvps.org/winsock.htm for additional XPSP2
info/approaches using the netsh command.

An alternative approach with necessary .reg files which will often work even
when the above doesn't is defined here, courtesy of Bob Cerelli:

Remember - you need to do this ahead of time.
