Ping:connection fine.IExplorer refuses to use the connection

Hi!

I think this is a weird problem.

I am running XP home and IExplorer is refusing to use my existing internet connection. The weird thing is that the connection is fine: when I ping a known server, I get replies (see below).

Below I followed up on some of the suggestions in other posts to get some info about my connection.

Everything else works fine. The network is wireless, as you can see below, IExplorer is working fine one my other computer. I am running mcafee virus software with up to date virus definitions... none found.


Any info would be appreciated, I hope you can help,

Dennis

tracert 66.102.9.104 also returns 'Trace complete' in 11 hops.


This situation seems somewhat similar to the problem posted by
Alkatr0z (internet Not working, no hostname resolution; may 26th).

The reason I think the situation is similar is that I used to get junk characters too when pinging. (Pinging ►; with 32 bytes of data:). This cleared after reinstalling IE6SP1, although the problem persists. So with me too, hostname resolution appears to be the main concern

Try an OZZU search for

DNS cache resolution (select any terms and the Windows forum)

You'll find several posts where others have had this problem. See if any of them help you.

Thanks for replying!

I searched the forum, also before posting; I went through the two pages of hits for the query: DNS cache resolution (select any terms and the Windows forum). Indeed some posting sound rather similar. I have tried the suggestions in there.... no luck.

I am sure I have the DNS settings correct: the DNS should be IP of the router. This works fine, right at this time, for the other computers on my LAN (two others) and used to work for my laptop (which is the one bugging me now).

Also when I enter for example the IP address of google directly in the address bar IExplorer cannot connect. (shouldn't this at least bypass the need for a DNS until I get to the page itself?)



I have tried the following:

entered IP numbers of DNS of my ISP (and of another DNS server I know is up)

Disabled WINS resolution

I had already tried uninstalling IE6 and then reinstalling from my original CD (and reinstalling IE6SP1 by downloading the full package using my desktop computer, by "c:\ie6setup.exe" /c:"ie6wzd.exe /d /s:""#E" ).

I am not running kazaa or other p2p or whatever on the laptop. Never have, it's for work.

Also, other software, for example my SSH2 shell I use to connect to the server at work, can't connect to the net. The annoying part being that I can ping the server from the same laptop and get a reply.... all the time!
It really seems windows doesn't know where to look to access the internet. For example the problem persists when I use my ethernet (non wireless) port to connect my laptop directly to the router. I can ping the whole world but cannot connect to the web...

When I run Network Diagnostics in XP Help and support: DNS comes up [passed].



This is driving me crazy... I have no clue where to look next?

thanks for the suggestion though,
Dennis

you may have firewall software that can be blocking access to the web

well, if u can ping other ips, and cant connect, possibly, something corrupted winsock keys possibly? like spyware....

Or the router itself may be disabling TCP access

I spent 45 minutes the other night tryin' to figure out why I couldn't get the damn wireless machine online.

The machine booted up, it had network access, the router allocated it an IP address, I could ping other machines on the network, other machines on the network could ping it, all the other 3 machines could get on the web, but that one couldn't, wouldn't connect to MSN, check E-Mail, nothin'.

Then it finally dawned on me.

I set it to disable TCP access on all ports after 9pm (so that when they kids are using it, they know it's time to go to bed).

Like I said, I farted around for 45 minutes before I finally realized.

Hi Leo, Foxy and Axe, thanks for replying!

To answer your questions:

1. Alas, no firewall.
2. I don't think the router is blocking TCP traffic. Two other computers on the same network are doing fine, same router.

3. corrupt winsock keys? The laptop I use for work, no games or downloads installed there. Nevertheless, some spyware may have gotten on there... Any suggestion on how I could check for corrupt winsock keys? and repair them?

thanks,
Dennis

If you know someone else with a win xp machine, you can just copy their winsock and winsock2 files. Then using regedit, go into your registry, delete your winsock and winsock2 files. I would suggest rebooting after doing that. Then copy the new winsock and winsock2 files onto your computer and double click on them to insert them into your registry. I would suggest restarting your computer again after you do this. Then hopefully all will be well.

Hi Shedevil,

Come to think of it, I reinstalled XP from my original CD over my existing setup and after reinstalled IE6SP1. Do you think it's possible winsocks are still corrupt after that?

Dennis

Hi all,

I tried using winsockxpfix.exe, as suggested in this thread http://www.ozzu.com/sutra80727.html#80727.

Also didn't work. I can still ping the world but IExplorer refuses to access the net. The problem should be somewhere with the DNS settings given the following:

C:\Documents and Settings\wv>nslookup
*** Can't find server name for address 192.168.123.100: No response from server
*** Default servers are not available
Default Server: UnKnown
Address: 192.168.123.100
>

192.168.123.100 is my router and should function as the DNS:

C:\Documents and Settings\wv>ipconfig /all

It doesn't however for the laptop, but does for the other two computers on the same net, using the same router.
As suggested on this forum, I tried using the ISP DNS IPs but that didn't work either.

Any suggestions?

Thx,

Dennis

Bypass the router completely with that one system and connect your ISP modem directly to that PC obtaining automatic settings.

or static settings if that is what your setup should be with your ISP

Sorry! I should have said all this in the same reply. This is just to troubleshoot & eliminate router problems with that one PC. Sometimes just resseting routers and switches will clear things up as I have experienced in the past.

Before reading the rest of the thread, I just wanna reply to this bit...

You can block specific access just to a single IP address.

Our router is setup so that ONLY the machine in the living room is blocked after 9pm. The other 3 machines hooked up to the router have 24/7 access.

Is the router one that has a webserver? Can you http onto that? That would prove if its the router blocking it or not.

Checked you don't have any junk in your proxy settings? (tools>Internet Options>Connections? or any other strange internet settings (get another working PC alongside it and match all the IE settings against eachother)

You should defs get google for instance if you put its IP http://66.102.11.99 as it works for me. Other than the fact that it teaches you a lot fault finding like this, if you finding its taking a long time to resolve it may be quicker to just bite the bullet and reformat? Not a great answer I know but sometimes nasty problems like this are just quicker resolved by a rebuild.
