Did you ever get your PC working? If so, what was the problem, because my main PC now has the same problem as far as I can see: I can connect over the Internet using FTP and HTTPS, but not HTTP. (I haven't tried email yet because I want to leave my emails on the server for now.)
[My problem started when I (eventually!) got my PC working again after accidentally installing an old Beta upgrade to Microsoft .NET Framework. That locked up my PC every time I rebooted it, and I eventually fixed it by completely removing .NET Framework, but that left me with the HTTP problem.]
Internet Explorer's "Diagnose Connection Problems" tool (available when it fails to load a web page) eventually led me to the discovery that it was just HTTP that was affected, and that FTP and HTTPS were fine.
I *might* be able to fix the problem by rebooting my PC, but I'd rather find the real cause.
A quick correction to my previous reply. I *had* uninstalled .NET Framework yesterday for the reasons I explained, but I *did* have HTTP access immediately after that. My HTTP problem only emerged today, after I had woken the PC up from hibernation overnight.
I am in desperate need of some help. I am in the UK and have recently
changed my ISP from Virgin to Sky. Apart from the atrocious and pathetic
service offered by Sky to me, I have discovered that my internet connectivity
is down because of a Winsock error. The diagnostic program Netdiag is so
unreliable that although it first notified me that the error was due to an
LSP in the Winsock, it has never notified me since I deleted the Registry
entry and the Program folder entry about the error ever again. Instead the
Netdiag tells me that it cannot connect to the internet because the http,
https and ftp ports are blocked by a firewall which is wrong because I turned
the firewall off (rendering myself vulnerable) only so I could connect to the
internet.
After trial and error connections on many occasions I saw the Microsoft
support page http://technet.microsoft.com/en-us/l.../bb457156.aspx
This advised typing “netsh Winsock reset catalog” in front of the C prompt.
Although I have restarted the computer on a number of occasions, doing that
has not restored connectivity even though the Winsock has been reset
according to the computer.
I only manage to connect to the internet by trial and error after many
messages that the problem may instead be in the modem and to turn the modem
off and on and then to contact my ISP which is pointless because as I
mentioned above Sky broadband hardly ever respond. I tried another ISP and
the computer connected without any hassle so the problem is with the ISP
although I just want to make sure before I take the rogues at Sky broadband
to court. Does anyone please know what to do about the Winsock error other
than spending another 100/- and reinstalling windows and losing data just
because Sky Broadband is a third-rate ISP?
I also have received information that this is a Registry error but again am
not sure how to ascertain or remedy that.
I await your kind response.

Just to complete my story, I did eventually get the problem fixed, but only by sending my PC away to have a clean Windows reinstall (I'd lost my installation CDs so I couldn't reinstall it myself; fortunately I still had my licence details).
Reinstalling Windows did mean that I have to reinstall all my applications (I am still doing that, but only on an "as needed" basis).
And when something (I forget what) demanded that .NET Framework be installed before it would work, I made absolutely sure that I had a full backup before installing it. But that was over a month ago, and so far (touch wood!) everything seems to be OK.
I had the same issue. For me it was caused (more than once) when Windows forced a hibernate because of low battery while my Sprint mobile broadband wireless modem was active. I am running Windows XP SP2.
Symptoms are the same:
- HTTPS connections work normally
- HTTP connections error out with no error code
Same symptoms from using either Chrome or IE7.
I believe the underlying issue is that the winsock registries become corrupt.
Here are the resolutions that have worked for me:
1. Run "netsh winsock reset" from a command prompt and then reboot. This worked once and had no effect the second time.
2. Run "netsh winsock reset catalog" from a command prompt and then reboot. This worked for me the second time this issue occurred when the first option failed. Not that this option netsh command is only available with Windows XP SP2.
Hope this helps save a few hours from someone's day.

Cannot connect via http but https works?
When I run connection diagnostics in IE (Windows XP Pro)
it reports FTP OK, HTTPS - OK, but could not make HTTP connection
Only one computer of three on my adhoc workgroup reports this error.
It reports this error for both wired and wireless connections that are
otherwise available.
Sure enough, I can connect to email, newsgroups, and FTP and websites via
HTTPS.... only HTTP won't work.
What's the problem and how do I fix it?

so be generous with it <g> turn the computer OFF and wait for the time to go

Then Turn the Router/Modem ON and wait a minute or so then Power ON the
computer and try to establish a connection and try the link, does it work?.
If still then continue the heavy work:
Open windows Explorer and locate the Hosts file and Rename it to Hosts.OLD
Reboot the machine and try, does it work.
If not try this:
search for them by this name *index.dat* and you can delete them
then the on reboot the system will recreate them for you.
Some of them here:
C:\Documents and settings\Administrator\Cookies = index
C:\Documents and Settings\User\Cookies = index
C:\Documents and settings\User\User data = index
C:\Windows\Temp\Cookies =index
C:\Windows\Temp\History = index
C:\Windows\Temp\Temporary Internet Files\Content.IE5 = Index.dat
Reboot your machine and see if this helped.
Check your connection (TCP/IP setting) are set correct.

I tried all the above, I still cannot connect with HTTP.
Only command that did not work was ipconfig /flushdns

All ipconfig settings are normal, I use a wireless and wired linksys router
which allows two other computers to operated normally. The defective computer
connects normally thru this same router (by wireless or wired) via ftp, thru
newsgroups and also to secure www via https but still will not connect via
HTTP only.
Anyother ideas?

Just some additional information. This problem occured after I un-install
EZ Trust firewall/anti-virus after which I had no connectivity at all. After
researching and trying many different suggestions including those in the
first post below the original posting, I found connectivity was restored as
mentioned above... all except HTTP. I think the clue may be that something is
blocking port 80 on this machine since FTP, SMTP, HTTPS and news all have
the ability to connect.
How do I find what is blocking port 80??

Raymon,
One of the things tried above was the native Winsock reset. Our experience here
has been that several different tools, each with its own different ability to
reset a problem, can be necessary to fix LSP / Winsock. If you've just un
installed a security product like the EZTrust suite, this is definitely a
possibility.
<http://nitecruzr.blogspot.com/2005/05/problems-with-lsp-winsock-layer-in.html> http://nitecruzr.blogspot.com/2005/0...-layer-in.html
And look at the LSP enumeration process too, if corruption isn't the problem.
This will give you a hope of identifying the port 80 block.

Thanks for the help, it at least gave me some more things to try.
I downloaded and ran the LSP fix program but it did not help.
So far everything checks good when I compare with two other XP machines
that have good connectivity. Only difference is the
lack of HTTP, and the only test besides the two browers that won't browse is
the MS Network connections test built into IE, as reported previously.
Still looking for more ideas,

How many HTTP hosts did you try, that didn't work? How many HTTPS hosts that
did? Did you try to access any hosts by IP address?

I have tried many HTTP sites both name and IP address, none will connect. I

I have gone thru all the ideas about DNS.. don't think that's it.
I have reset and/or reinstalled TCP/IP several times.
Pinging with 1472 bytes works so not a MTU issue according to your website.
I have not tried the Cerelli registry key reload although I may try that
later today.
At this point I'm not sure that it's a registry issue. I have restored my
registry
at least once to a point before I had the problem. Still no luck.
Still looking for more... short of a complete format HD and re-install....
Much thanks for all help... I am quickly becoming a networking expert...
