    lost network connectivity

    A few days ago my main pc "blew up" while attempting to upgrade IE6 to IE7. I believe I was somehow redirected, as the installation did not show the usual permissions for this upgrade and actually was placing something on my backup external drive. When I next looked the pc was locked during a reboot. After a forced reboot, the system came up with very strange behavior. IE was still at the 6 level. Various Windows functions did not work. I took the system offline and removed some strangely behaving software such as Spyware Doctor and MIONet. After rebooting, the system said it found a new network and asked me to set Internet or Trusted security. I did the former. Since then the system seems totally stable -- but without network connectivity.

    The system tells me that I have "Limited or no connectivity. You might not be able to access the Internet or some network resources. The problem occurred because the network did not assign a network address to the computer." All my other pcs connect without a problem. Reconfiguring the network (by moving plugs) does not cause any other pc to malfunction, nor cause the failed pc to function -- whether plugged into the network router, network switch, or directly into the cable modem.

    I've run ZoneAlarm's antivirus and antispyware on both PCpc hard drives and the external (backup) drive. I also ran Sophos Anti-Rootkit; it found 5 minor items but said not to remove them. [I removed three anyway.]

    I've tried changing the network from Internet to Trusted, with no change in behavior.

    Any thoughts as to how I might regain network connectivity?

    BTW: For some time a routine dalled "taskswitch.exe" was fingered by Skyware Doctor with the question to allow or not. I do not find this routine on my other pcs. However, this pc had an Intel hyperthreading processor; I don't know if that makes a difference.

    Re: lost network connectivity

    Have you tried running WinSockXPFix ? When all else is failing it can be just the thing to get everything back to normal.

    Re: lost network connectivity

    The good news and the bad news:

    I downloaded the WinSockXPFix to my laptop, took it to my main desktop, installed it, ran my back-up program, created a new restore point, and ran WinSockXPFix. After rebooting, I had network connectivity again, and everything appeared normal. Great!!!

    Then I showed my stupid side. I thought I would try the IE6 to IE7 upgrade again. I used the normal Help & Support approach to go to the MS site, clicked on the IE7 upgrade, and said "go." The system said that it already had the files and started installing. Everything looked normal except: (1) I did not receive the usual IE6>7 upgrade okay and license approval screens, and (2) as before, the activity included writes to my backup external disk drive. I could hear disk writing for 10-15 minutes. After the requested reboot, things appeared normal except for the message that IE7 was not installed. These are all exactly like it was before disaster hit a few days ago. Therefore I updated the ZoneAlarm antivirus and antispyware definitions, put the ZoneAlarm internet lock on, and am now running ZoneAlarm's antivirus and antispyware on the C, D (also internal), and Z (external) drives. This will take several hours, as there are about 850 GB of data on these three drives. My assumption is that something co-opted the IE6 update so that I need to remove some loaded malware before I can do the update.

    Any alternate theories or suggestions?

    Thanks again.

    Re: lost network connectivity

    I reran my virus and spyware checkers as mentioned; they found nothing, although once again the pc hung during the virus checking. I then reran Sophos, and it only found the same "restore" item on my Z (backup) drive. This looks like a registry key; I removed it. So I'm back in operation, but wondering how to get rid of the incorrect info stored on the pc that pretends to be the upgrade to IE7. Any ideas?

    MANY THANKS!

    Re: lost network connectivity

    Glad you've got connectivity back anyway.

    How about trying a reinstall of IE6, which can be downloaded from here.

    Or forget about IE and move to Firefox from here

    Re: lost network connectivity

    I just tried IE6 from the site you recommended. It started, and then I received a message (paraphrased): "A previous installation needs to be completed first, and requires a reboot. Please complete this installation first." [I have not installed any new software (knowingly) since the previous reboot.]

    I fear that a reboot would produce the same result as my previous failures.

    <img src=/S/clapping.gif border=0 alt=clapping width=19 height=23> Amen. I've kept IE on my computer simply because everything Microsoft requires it, but FF and Opera are both nice, and FF has a plugin to allow you to view IE specific sites.

    Re: lost network connectivity

    Do you think I might move to Firefox, remove IE6, and then install IE7, removing Firefox?

    Sounds complicated, but I need to flush whatever installation files are hanging in there, masquerading as an MS update. Of course, the real problem might be with Windows XP.

    Re: lost network connectivity

    Unfortunately, I do not think you'll be able to "remove" IE6 (or IE7 for that matter). Maybe I'm just repeating bad information (someone will correct me if I'm wrong), but I find IE so tightly woven into Windows, that there just is no way to do it.

    I would suggest using a separate internet browser, such as Firefox, or Opera. Both are mature applications, and both are widely used.

    Re: lost network connectivity

    Understood, but how do I prevent the "stuff" that is waiting to be reinstalled from installing with the next round of MS updates? Somehow I have to flush the malware from the installer cache (if these are proper terms).
