Can not open a Particular Website

Problem since Last 3 months

[ashii]

I can not open a particular website from my Computer when every one else in the world can open it.
it will just timeout.
I see two possibility:

1)Site is hosted on an uncommon port which my ISP blocked,so is there a way I can find which port site is hosted so I can contact my ISP and request them to open it.

2)My Router is not configured to to goto that port.

any advice?

Try deleting cookies, internet files, etc... to see if it changes anything.

You should also check your "hosts" file to see if there is an entry for the site, either pointing to a local resource or an incorrect IP address.

Otherwise, if you ping or do a traceroute to the site do you get a response?

Also check your ad-blocking software if you have any to see whether the site URL is triggering something.

I've had this problem and it was always either Norton or McAfee's fault.

It may also be worth your while to search for "DNS Resolver Cache"

DNS Resolver Cache

That's a good idea, if you're running Windows you can flush your local DNS cache by typing "ipconfig /flushdns" (without the quotes) at a DOS prompt (Start, Run, cmd).

It may also be that the site is blocking you.

Did not help,problem is with every computer I have(Same internet connection)

You should also check your "hosts" file to see if there is an entry for the site, either pointing to a local resource or an incorrect IP address.

Checked that,no entry there except for blocking Google adsense.

ipconfig /flushdns

Did not help

problem is since last 3 months(in fact from the day we registered that domain).In beginning I think its name server that will be solved itself but 3 months are too long.not so...

Domain is a for a Child nursery school site in Labenon,so I see no reason if it can be blocked at some lavel.

It may also be that the site is blocking you.

I create that site & I am the only one who can access its cpanel.so I don't think I am blocking myself.
Between site is hosted on Network solutions,if that helps.
I can access Network solutions control panel without a problem.

Also I can not open site but I can acess mail.domain.com

so I I still guess its some Port problem.

You don't have to guess. There are tools to diagnose this, and you should learn how to use them.

ping, traceroute, telnet. Those three should be able to tell you exactly where the problem lies.

Something here doesn't compute, though... You created the site, and you don't know what port number it is using?

This is what I would do from a Windows command prompt:

tracert www.widgetsite.com
Does the it give an IP address? If not then it is a DNS problem.

How far does the traceroute get?
The problem most likely is with either the last router you get to, or the next one you don't get to. (Find out the next router by tracing from outside your home.) If the problem is not with your web hosting company, then complain to your ISP about the network reachability problem and show them the traceroute(s).
