IE7 cannot connect to internet but can use msn and ping google


I'm dealing with the following issue:

- I can ping and recieve return with no packet loss
- I can use msn messenger
- I can ping my router and othr networked computers
- I cannot connect to web pages via IE7
- I cannot update AVG free - "connection to update server failed"
- The computer has been rebooted numerous times
- The internet is known to be working because I'm posting from it.

The computer runs Windows XP SP2 is connected by ethernet to the router.
The windows firewall has been disabled.

My "Network Connections" tab in the Control Panel reads:

Lan or High-speed internet
- 1394 Connection - disabled
- LAN connection - connected

I am now rather stumped. Any help would be greatly appreciated.

  1. Try this
    goto Iexplorer|tools|advanced and hit reset

    Also get to a command prompt and type
    ipconfig /flushdns

    Im pretty sure that will fix you up. If not schedule your AV for a scan at boot up.
  2. Thanks for the reply pat,

    I'm trying the reset now, already /released and /renewed in ipconfig, but can try /flushdns.

  3. I'm having trouble getting Tom's to post - get blank page or "cannot display message". Hence multi post.

    I've tried both of your suggestions but with no success.

    Could this be a ports issue on the computer?
    Or a winsock issue? (whatever that is!)

  4. I also cannot browse to my router.

    It just seems to point to this being Internet Explorer not looking for or using the LAN to attempt to connect to the internet. Thoughts?

    Also installing Firefox 3 to see if this is just an IE issue, although given that AVG doesn't update I'm not convinced.

    Update: Neither IE7, Firefox nor AVG can access the internet despite which MSN is still working perfectly.
  5. Another update: Using the "set up small / home network" wizard doesn't work either. Set to connect through the residential network in the correct workgroup (MSHOME).

    Update: Run sfc /scannow from cmd prompt. Possible missing dll's, need to get the XP CD from the computer owner.

    Does this give anyone a clue as to what the problem might be?

    Still very confused.
  6. Update: Run sfc /scannow from cmd prompt. Possible missing dll's, need to get the XP CD from the computer owner.

    Does this give anyone a clue as to what the problem might be?
  7. Is this a new build? Or was it working and suddenly failed? If it suddenly failed, when?

    It certainly sounds like a virus. Remember, not all viruses are caught by any particular program. I would try grabbing the latest Avast or Trend or some other free DL. Possibly HiJack This, and a registry repair utility.
  8. Thanks for the reply Proximon,

    This is a system I am looking at for a friend. It is an old Dell 4550, she wants to be able to connect it to the internet via a new router - hence trying to make it work!

    She has never used it to connect via a router, or at least it hasn't worked if she did. Previously she has used dial-up broadband.

    Would it be useful for me to post the Hijack This log file?

    I've tried a sfc checker scan, which seems to want the XP CD, probably suggests that there may be some problems, I'm slightly wary of letting it update them all incase I bring more trouble upon myself.

    I'll get a hijack this log done and give it the once over with a new virus scanner.

  9. This si the Hijack This log file from the machine:

    As far as I am aware Norton has been removed (by the looks of things incorrectly) from the system. There are no files relating to it on the hard disk.

    I am running a virus scan using AVG Free 8.5 with a database from last month - found nothing other than tracking cookies and a BT openworld dialer that it has marked as potentially dangerous and removed.

    Still won't display webpages or access internet to update AVG definitions.

    Since you've also ruled out a DNS problem by trying to reach a "real" IP addresses like:

    It's looking like port 80 (the http port) is being blocked. Which helps explain why you can't browse to your own router and why MSN Messenger is working since it uses TCP ports 1863 and 443.
    Previous success connecting to the Internet seems to indicate a good winsock protocol stack.

    You already disabled Windows Firewall. Is there another security suite installed that might have it's own firewall?
    No real success using google to source a solution. Did find this:
  11. Thanks for your help again WR2,

    I can ping the IP addresses and their www. counterparts.

    I agree that port 80 maybe be blocked, but it is definately at the PC level rather than the router as all my other networked pc's (including this one work fine).

    Is there an application that would allow me to "see" what ports are opened and which are closed?


    Edit: I have checked the beer234.blogspot and that registry entry is set as requested.
  12. Visit and use the Shields Up test.
  13. Does she have any other firewall possibly built into the router?
    Try putting the computer on the other side of the router for a few minutes
    to see if it can connect. If so then that will help to narrow it down.

    As for the AVG free i thought they didnt update that anymore.
    I had it for a while and then it told me that I would have to but it to continue si I got something else.

    Ok after looking at the Hijack log I have possibly found something
    R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyServer =

    Im not great with networking but give me a little time and Ill boot into XP and see
    what settings I have.
    The trick is I am not behind a router so my settings would pertain to getting to the internet without a router but I still think that is where the conflict is.
  14. That line set off my alarms as well.

    Can you just back up the files and install XP fresh on a reformatted disk? I'm pretty sure that would resolve the issues.
  15. Thanks for the replies again,

    WR2, I can't test with ShieldsUp onto the computer in question - I will try it onto the network - though I think the problem lies with the machine rather than the network.

    ShieldsUp test returns all ports as stealthed.

    - The computer is running on my own network (I've bought it home with me) and that network is the one I am posting from. In principle the network works fine, it could be an issue between machine and router.
    - Unfortunately I have a modem built into the router so I couldn't test without router. I am going to try it on our other network this evening, haven't had time yet.

    - It would be useful to know what settings you have for the R1 entry. WR2 if you have Hijack This and could run it that would be interesting to.

    Thanks very much (again!)
  16. Proximon, I don't have access to all the programs that she has on her machine at the moment. I could if needed do a complete reinstall but I was trying to avoid it.

    This started out as "could I install some extra RAM...."
  17. LOL it always does start that way ;)

    Still, I would go through the program list and uninstall anything not needed or wanted. Then I would run a registry cleaner.

    I would also look through the running processes in task manager and google anything suspicious.
  18. I've already run CCleaner on the registry, although I'm thinking of deleting the Norton instances because I think that was a bad uninstall.

    I'm currently running sfc, which appears to be copying in some dll's, see if that solves the problem.

    Could this be a winsock issue? It keeps popping up on my searches but I don't really understand what it is.

  19. Run sfc, seemed to have used the XP disk to retrieve some files, but no success in terms of IE. Does it have a way to check results?
  20. Ok Im on XP now so maybe i can be of help.
    try this
    control panel|network|connections|right click lan|properties|hightlight tcp/ip and see its properties
    In mine all of the all of the top checkboxes are checked, in all options.

    Under advanced
    in ip settings
    ipaddresses dchp enabled and automatic metric

    In dns
    top 2 appends and register are checked

    in wins
    lmhosts and default are checked

    in options
    tcp/ip filtering is in box
    and its properties are all yes.

    Im thinking since she was on a dial up possibly try to create a new connection and use the defaults to see if it doesnt help.

    I have a feeling that the other connection is the cause of the proxie setting and the new one wont have that.
    I also think that maybe the proxie is the one using the port 80 as its own so you may have to disable that connection so port 80 opens up again.
  21. Thanks Pat, I've checked all my settings and they are the same as yours.

    If I use the wizard to set up a new connection I get "Your broadband connection should be configured and ready to use". I don't know of any other method to set up a connection.

    I'm feeling more convinced that this is a port 80 issue - I just don't know how to solve it.
  22. Just found this interesting command: netstat

    The syntax allows me to check which ports the computer is listening to and which connections are active.
    Noteable neither syntax shows that port 80 is active.

    I comparison the laptop I'm using now has loads of connections open on port 80 and one on 31335. Using the -n command.


    Also netsh command seems to have lots of functionality, but I don't really understand how to use it. Anyone more skilled?
  23. here is a link for tcpview from MS
    It is a little easier to read and also gives you process numbers that you can use in either task manager or process explorer which is another MS tool that can help see what is running and causing this.

    One other option would be to delete that connection and create a new one which should contain only the default settings.
  24. Hi Pat,
    I've been wondering about deleting the connection, but I can't find an option to do it. Sort of uninstalling and reinstalling the network card.

    The right click options don't include delete.
  25. If you unplug the cable I think delete will become available.
    I cant delete mine either but then I am on it.
  26. A cunning plan - I shall try it. I've just checked for a more recent firmware revision, but there doesn't seem to be one available.

    Not quite cunning enough - still doesn't allow me to delete it - neither does disabling it and unpluging the cable.

    Going to try a wireless adaptor, connect to a different router.

  27. One more trick up my sleeve.
    goto device manager and disable the network card and try one of these.
    Then try to delete it. If not try to reboot and check device manager if it is still disabled then try to delete it.(the connection)

    If neither of those work I have on more trick but you will nedd the network card drivers for that so save that one for now.

    Ps dont go for firmware only drivers if necessay. Lets not add to the problem.
  28. Right, somewhat unsurprisingly - I connect the wireless adaptor, set it up as the only available network connection. I can ping but Ie still doesn't connect.

    Probably confirms that it is the http port that is not open - however I have no idea how to open it.
  29. In control panel network connection on the left side there is a repair this connection.
    What does that say when you try it?
  30. Pat, I still can't manage to delete the thing, the option is there but greyed out.

    I'm just going hunting for the drivers.
  31. Have you run a AV scan and a spyware scan lately?
    Something seem fishy here.
  32. The repair connections tool runs through various different things, ending with "Windows has finished repairing your connection you can try connecting again".

    Just about to update the device drivers now. Latest version from Intel website.

  33. I've done a scan with AVG Free 8.5 with definitions from last month, and the computer basically hasn't been used on the internet since before then - I'm supposed to be enabling it for network broadband.

    It didn't find anything other than tracking cookies.

    New drivers haven't made any difference, still same issue with non-connection.

  34. I think Ive had a brainstorm
    Cmon they happen

    goto control panel|internet options|connections|lan settings
    is it on automatically detect settings as it should be?
  35. I'm afraid so...
  36. ok while we are there look at these
    in the first window under connections is the dialup and vpn box empty?\
    Also is the never dial a connection empty?
  37. The dialup/VPN box is empty. Never dial a connection is selected but greyed out.
  38. Not to worry we arent done.
    Hope you arent in England or somewhere and have to goto sleep.
    If so let me know. I dont have to work tomorrow or the next day, or the next etc.

    goto the same place this time programs and goto addons and disable all of them.
    Also goto start|run type msconfig and goto startup
    uncheck anything that you dont think is important and reboot

    Something is causing this and we will find it.

    I should have realized it would be difficult to get the to run on the other computer.

    My Hijack log has an empty entry @
    R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyServer

    Have you tried booting up in Safe Mode with Networking? I think you'll need to create a new broadband internet connection from inside safe mode. The existing profile won't be available IRC.
  40. Hi Pat and WR2, thanks for the replies again,

    I'll have to get back to you later as to whether they are successful, anything else you think up would obviously be greatly appreciated!

    Also Pat you sent me a PM, but the forum isn't letting me get at it at the moment.

  41. Let's recap, we've come throught loads of stuff thus far:

    1. The network itself works - other machines are using it

    2. The connection to the internet works - other machines using it

    3. There is some connectivity from the machine as msn works and can ping websites - implies that some ports are open and avaliable

    4. Can ping and its respective IP address from command prompt - implies dns is working

    5. Neither IE7, Firefox3 nor AVG Free can access the internet but MSN can, windows firewall is disabled - implies this is not an application specific problem.
    - NB: AVG Free uses port 80 to update

    6. I have created a new network connection using wireless dongle connecting to a different router and still the problem persists - implies an issue above the network layer.

    7. Hijack This picks up an unusual line entry R1 with proxy server and it has come to light that the machine may have been connected to a local govenment server via a home router (proxy?)
    "R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyServer ="

    8. Machine has been checked and found virus free.

    This seems to be an issue somewhere between the network layer and the application layer.

    Possible causes:
    - R1 entry in registry - trying to access proxy server at low level
    - Port 80 (http) is blocked in some different area.

    - It would be usful to test over various other ports - pin it down to just port 80
    - Work out whether just editting the registry entry would solve the problem? (Can I just try it? If so how?)

    Thanks for the help again!!
  42. Here is 2 things that I wold like you to get.
    Mostly the second one but the first one is pretty handy also

    The first one is a better task manager and the second one will help us to look at what ports are doing what.
  43. Pat, what am I looking for, I'm about to boot up and install those tools.

    Now got msn failing on me due to a "key ports" error. Not sure what that is about.
    But pinging still works fine.
    Also just tried accessing the itunes store - that won't go either.

    Edit - now installed:

    So from Process Explorer selecting the instance of IE in the TCP/IP tab I have:
    - Resolve address - checked
    - UDP | localhost:1030 | *:* | blank
    Selecting the MSN messenger instance I have:
    - Resolve address checked
    - UDP | localhost:1031 | *:* | blank

    From TCPView looking at the IE instance:
    - protocol is set to UDP
    - process name is iexplore.exe:3628
    - localaddress is set to the name of the machine
    - remote address is set to *:*
    - state is blank
    For msn instance
    - Process name is msnmsgr.exe:2080
    - All others are the same

    Also I've previously tried running IE with no add-on's but that didn't seem to help proceedings.

  44. Just install those with a icon on the desktop so you can find them.
  45. Yep, got them up and running.
  46. in tcpview do you see this address in there anywhere?
  47. No, any entry under local address or remote address is the full computer name or *:*. doesn't occur in any of the other columns either.

    Noteable it also doesn't appear on TCPView on my laptop.
