Cannot access one specifc web site in IE7
I'm stumped. I cannot access http://partner.dell.com from IE7 - it takes
several minutes (more than 10) and, of course, in frustration, I close the
browser.

Yet, if I ping that url, the response is fast:

Pinging partner.dell.com [209.34.90.69] with 32 bytes of data:

Approximate round trip times in milli-seconds:
Minimum = 102ms, Maximum = 104ms, Average = 102ms

If I run a tracert on that address, the response is fast:

13 103 ms 103 ms 102 ms 209-34-90-69.ood.opsource.net [209.34.90.69]

Trace complete.

So, through my command prompt I can access this address very quickly. What,
in heavens name, is preventing the browser from getting there?

I'm open to any and all suggestions, or questions about this workstation.

For what it's worth - I can't get to that URL using Firefox, either - same
symptoms.

Thanks!

Larry

Re: Cannot access one specifc web site in IE7
Hi,
Windows XP or Vista? (Might or might not matter.)

Try clearing the DNS Cache
Start> Run> cmd [enter]
ipconfig /flushdns
Then clear the Temporary Internet Files and restart.

Next, if necessary, clear the History and clear all cookies or find and
delete all cookies from dell.

Next, if necessary, disable any third-party firewall to see if it's causing
the problem.

Hope this helps,
Don

ping doesn't test http. Try using telnet and o partner.dell.com 80
to do that...

<telnet>
Microsoft Telnet> o partner.dell.com 80
Connecting To partner.dell.com...
</telnet>


Hmm... are you sure you are using the correct protocol with that site's server?
Let's try simulating a connect request with https instead...

<telnet>
Microsoft Telnet> c
Microsoft Telnet> o partner.dell.com 443
</telnet>

and that works but of course I can't do anything more than test
the connectivity that way.


....

There is no http server there. Try instead using:

https://partner.dell.com/

Hmm... that redirects here, so I think the Address bar's contents
are bogus:

http://partner.dell.com/Main/Pages/D...C/default.aspx

E.g. we already proved that there is no HTTP server port open.

If there really is an HTTP connection you could trace it with Fiddler2...

which seems to indicate that now there is an HTTP port open. ; }
Telnet now finds it too. Well, I can think of several possible explanations
but must admit I have never seen symptoms like this before, almost
like they want you to use https to start or that HTTPS opens the
HTTP port temporarily, etc.

Re: Cannot access one specifc web site in IE7
That's what partner.dell.com "translates" into in the address bar - still
can't get there, though.

Re: Cannot access one specifc web site in IE7
I am running Windows XP SP3, and had previously cleared the DNS cache - I
frequently clear out the internet temp files.

I cleared the History and deleted all Dell cookies.

I turned off COMODO Firewall and disabled Windows Firewall.

Still can't get through...

Re: Cannot access one specifc web site in IE7
I never get a response back from Telnet after the "Connecting To
partner.dell.com..." message. Either with port 80 or 443.

Is there supposed to be a prompt after the connection is made?

Thanks!

Larry

Sort of. The cursor goes to the top of the screen when it is ready
to accept input. Try it with a host name that you know works to
get familiar with the technique before trying it with one that you aren't
sure of.

So, with o partner.dell.com 80 the cursor just stays at the end of
the *telnet* response:
Connecting To partner.dell.com..._
(Underscore represents cursor.)

I waited for a ridiculously long time. Usually those at least timeout
reasonably quickly. So, then you take advantage of the telnet message
Escape Character is 'CTRL+]' and press that to get back into the telnet
subcommand mode. Then you type c (for close, to kill that connection
request which isn't timing out.)

Now try with o partner.dell.com 443 and compare. Instantly the
cursor goes to the top of the window. For HTTP you usually at
that point would enter GET / (which I don't think would be right for
HTTPS) but as soon as I start typing I get Connection to host lost.

After that IE can use either protocol with that site. YMMV.

Did you try using Fiddler2 yet to see what it thinks about connecting
to that host? It does support HTTPS in a way but as the FAQ explains
trying to use it inevitably results in certificate problems because then
Fiddler would be acting as a Man-in-the-middle for a secure connection.


Good luck

Re: Cannot access one specifc web site in IE7
Robert,

Thanks for the quick tutorial on Telnet.

I just downloaded Fiddler 2 and ran it against the partner.dell.com url.

Start time: 10:54:22:437
End time: 11:00:51:1562

I'm going to have to read up quite a bit to see what the "hang-up" is.
There are several large javascript files in the load routine, and I'm
wondering if there are some settings - either in the browser or in some
software package my PC is running that's causing them to lag.

Larry

Whoa! Has your symptom changed now? I was interpreting your
symptom description strictly as a connectivity issue. I thought that's
what your ping test was trying to check and that's why I mentioned
telnet 80 as a better connectivity test. If you actually have connectivity
with that host you need to make a better description of your problem
symptoms.
