    connection problem

    I have a 5 computer network with a router and dsl modem. The problem happens with the machine running XP Home SR2. No problems with the Windows 98 machines.

    Sometimes it seems my connection dies. Like right now. I can't connect with a second window or by clicking on a link in the forums. I get a page not found message. But I can go to other pages here in the forums in this window. I also can't connect with Eudora Email. A reboot fixes the problem for a while. I turned off the popup blocker and firewall (XP's) No other firewall is installed. Anyone have any ideas?

    Re: connection problem

    Assuming you are using Internet Explorer, go to Tools, Internet Options, General tab. Select Delete Cookies, and then Delete Files to delete all your temporary Internet files (Note, this also will force the manual entry of usernames and passwords for sites requiring them on your next visit, so make sure you know them). If using Mozilla Firefox, go to Tools, Options, Privacy, and Clear All. No need to scan thousands of temporary files.

    Temporarily turn off System Restore to enable the scanner to clean any infected restore images. See here for instructions. This keeps malware hiding in restore images from coming back and reinfect your systems.

    Now scan for spyware. To ensure you have the latest scanner versions, download and install SpyBot Search and Destroy V1.3 from here. Before scanning, use the program

    Re: connection problem

    Hi Bill,
    I did everything in your post and didn't turn up anything at all. I do use ad-aware and spybot but hadn't gotten the new versions. Thanks. I am still stumped on this one. The problem doesn't happen every time. Just certain days it seems. But to often to ignore. What stumps me is the loss of my eudora email also. It seems like a connection problem. But if I go to another computer on the network I find it working fine. But thanks for the advice and information.

    Re: connection problem

    Bill,
    Which of the two firewalls do you like best? Have you tried both?

    Re: connection problem

    I use ZoneAlarm, as do most of my collegues. It is easy to use and set up. Plus it has been around for awhile which means there are lots of folks that know how to use it. Several forums offer support. I have not used the Sygate firewall but those that I know that do like it.

    I think it is just a matter of preference as neither appears to be better than the other. So all I can say really is get one, NOW - if you are not using one.

    As far as your connectivity problem, try swapping ports on the rounter and see if the problem moves. Also, try another Ethernet cable. I have seen some pretty weird problems with cables that make only partial contact.

    Re: connection problem

    I will get the firewall and give it a try. As for the other problem. -----
    Oh oh, I jusr put new connector on my ethernet cable to that computer. It seems to work, but maybe not. I will check that. I don't remember if the cable connector came before or after the problem started. I will try a different port in the router though. Thanks, I will let you know the results.

    Re: connection problem

    OK, I still have the same problem. I replaced the network cable. I moved the cable to another port in the router. I moved the laptop that is giving me the problems to another location and plugged into a connection that is not having any problems. And the problem is still here. So I know it is a problem internal to the computer and not with the network.

    My virus checker, the internet virus checkers, ad-aware, and spybot find nothing wrong.

    Now, I have gotten myself into a pickle. By turning off the restore points as was suggested, I lost all the restore points so I can't go back by using a restore point. I don't think that was such a good idea. I also deleted (dumb on my part) the service pack 2 backup file so I don't think I can uninstall service pack 2.

    I did everything in your post.

    Now, one of the clues I am puzzled by is that my Eudora email program also looses connection. So I doubt the problem is just Internet Explorer. What happens is that I will be on the internet and click on a link or a bookmark and get a page not found message. Once I get that message I no longer seem to have a connection until I reboot the computer. Today it is especially bad. Clicking refresh does nothing.

    Any other ideas? Anyone? Reinstall service pack 2 from the CD? I only have the restore cd's that came with the Toshiba laptop. I'm stumped.

    Thanks for any help.

    Re: connection problem

    Sorry about the restore options - it is one of those things that if we did not turn them off and there was some thing bad in there, it would have come back.

    I agree you have verified it is in that computer. You said that is a laptop, is the NIC a PC Card or internal to the laptop? It sounds like the NIC to me, assuming the computer is clean and you said you ran everything.

    Does device manager show any conflicts? Perhaps a removal and reinstall (rebooting in between) of the NIC drivers is in order - or try another network card?

    Re: connection problem

    Well, I checked in device manager and there are no conflicts. As far as the internal nic goes, it seems to work fine on the intranet. No problems there. I did upgrade the drivers for the card but it didn't seem to help.

    Huh? I thought losing connection to the Internet was the problem. What have we been troubleshooting?

    Re: connection problem

    Do I understand you correctly that you have INTRANET connectivity but your INTERNET connection goes down all the time? When you lose your INTERNET connection do you still have access to your INTRANET? Thanks!

    Re: connection problem

    Yes loosing connection to the internet but not to my home network itself. Maybe I used the wrong term. I thought intranet was my home network as opposed to internet for the outside world. Sorry to be confusing. As I was saying I can work inside my own network with the nic without any problems.

    Is it possible that the ISP itself could be a problem with XP and not with Win98? I ask because my college kid who comes home on weekends just told me he has the same problems on his XP SR1 laptop, but solved it by using Linex on the internet. Or could having a Linex machine on my network router cause me problems on my XP machine?

    Re: connection problem

    My bad! <img src=/S/blush.gif border=0 alt=blush width=15 height=15> You did indeed say intranet - which is your local "inside" network - as opposed to internet - which means the world. Sorry. Should have waited to finish my 2nd cup of coffee and read it again.

    Well, if your Intranet works fine, meaning you can see and share files on other computers on your network, but you lose connectivity to only the Internet, then it is not the hardware.

    And if your other 4 computers behind the same router are working fine, then it is not your ISP.

    SP2 is not designed to fix a broken PC, so I would not attempt that.

    So, it seems to me to be boiling down to either malware (virus, trojan, worm, etc.) or a firewall issue. And it seems if it was a firewall issue, then rebooting would not fix it and it would be consistent, but you said, "The problem doesn't happen every time. Just certain days it seems."

    So, that leads me back to malware. Did you try a2, Trojan Hunter, and the on-line virus scanners?

    If those scanners, and AdAware and SpyBot, do not turn up anything then I think it may be a HiJack issue and you need to run HiJackThis. If you run those scans and still have the problem then I suggest you go over to CastleCops (formally ComputerCops) and download: HiJackThis! from CastleCops

    Create and Unzip to a folder not on your Desktop or the Temp folder, double-click HijackThis.exe, and hit "Scan".
    Unzip the download (using WinZip) or something similar.
    When the scan is finished, the "Scan" button will change into a "Save Log" button.
    Press that, save the log in a text file, and post it in the CCSP "Spyware - Hijack this" forum: here

    Note that some of what it lists will look harmless but may be required, so do NOT fix anything yet.
    We have trained experts there who will be happy to help you analyze the results. Note that they get several hundred logs a day to analyze so give them a couple days to get back to you.

    As far as going to Linex may work but that opens a whole new bucket of worms. And note too that laptops are very proprietary, you may have a very difficult time getting linex drivers for yours.

    Re: connection problem

    I'll try a2, trojan hunter, hijack-this, and the online scanner (again). I wasn't planning to use Linex. Just thought I would mention the fact that the kid uses it and has no problems with the connection along with win98 having no problems. Thanks for all the tips so far. I'll report back what happens with the other malware programs.

    Great. Sorry you've been running around in circles here - this is certainly an odd problem.
