can't browse to one specific page

[google.1.jvmail]

As of yesterday, I am unable to browse to one particular page from any
of my computers. I have 43 computers on a router, so it's not a cookies
or cache issue. Also, my ISP can browse to the page. I'm wondering if
it could be my modem?

I have visited anonymous browsing web sites, and can browse to the page
in question via their anonymous browsing tools, so I don't know what's
wrong. Tried using a proxy to browse (in my IE lan settings), but this
won't let me get email, and I can't get it to work in other programs,
like Poster Toaster. Any advice? I'm really desperate at this point.

I've posted this to the three groups I thought would best be able to
help me.

Thanks

Maybe the owner of the page is blocking you.

Actually, I thought of that. I am the owner of the page, and was
wondering if there was an IP Deny on the site, but no, nothing there.
I'm wondering why, at 10am on Sept. 22 I was able to browse to the
page, and then, while working on the database via an ODBC connection, I
lost all view of the page. I can only browse to it via a proxy server,
which is much slower.

Thanks for additional input.

Very unlikely to be your modem.

Start diagnosing from first principles and simulate each step of a connection.

First of all you haven't given us your OS and version so I will guess
that it's NTx ;] Also it is much easier to discuss a specific example
than have to describe procedures generically.

Start by proving that your DNS knows the site's subdomain or alias
and is not getting a timeout finding it. E.g. use nslookup or ping -n 1
to do that.

If that seems Ok use telnet 80 to prove that you can get an HTTP
connection opened to that site. You can also try giving it something
simple like GET / (i.e. GET<space><slash><Enter>) as a request
to simulate the request that IE is giving and perhaps see exactly what
IE might be getting as an initial response. Etc.

Use of an alternate browser would similarly prove that you have some
connectivity with the site. In addition to that you could connect through
a proxy tracer such as fiddlertool to get some idea of what was happening
and compare the two traces.

Alternatively, the most accurate diagnostic would be to capture a packet
trace of the actual request by IE and the response from the server.
XP Pro users can use netcap from their Support Tools package;
others can use something like Ethereal. I use both, with Ethereal to format
the .cap files that netcap creates.


Note that while IE is involved with this problem that the real expertise
you need is probably in a networking newsgroup.

In any case here is an interactive troubleshooter which you can try.
It contains a link to an XP newsgroup which specializes in networking.

Thanks for the great link. I found the problem. It started when I tried
to access a database on my site via an ODBC connection. Upon thinking
about it, I decided to ask for a reboot of the server (which the host
was reluctant to do), or a change of my site's IP address. The latter
suggestion triggered the memory of the tech, and he checked the IP
block list, and then exclaimed "OH WOW, YOU'RE ON THE BLOCKED LIST!"

Obviously, I'm not supposed to be blocked out of my own site, so they
removed me from the blocked list. They gave me technical reasons why it
would take a couple of hours for me to be able to access the site, and
after about 5 hours, I complained again. They then rebooted their
server, which enabled me to access the site again. Don't you just love
technology?

Thanks for all your assistance.
