Website access problems - DNS/network issue?

[egomeister]

I've been trying to access a site I'm working on over the weekend but have been having some bizarre problems...

I appear to be the only person who can't access it. I've had others check it, and it's appeared fine so I can assume the site is online. I can even access other sites on the same hosting account no problem. I can access the ftp for the site through cuteftp, but can't get the site to display in the browser (Firefox or IE6) - it just returns page not found errors. Going through the problems with my webhost's tech support I was asked to perform a number of checks (he suggested using a program to ping/traceroute the address). Having analysed the logs he suggested the problem most likely lay on my computer...

So i tried another adsl modem, in case it was an issue with my modem/router. Success! For about a day.... and then back to the same page not found symptoms as before.

Does anyone have any suggestions what might be preventing my computer (and apparently mine only) accessing this site? I don't really suspect a virus etc as I run a virus checker and firewall so I should be reasonably well covered in that respect...

What's the website name..

What's the contents of your c:\windows\system32\drivers\etc\hosts file
What's the output of the following command from a Command Prompt (Start..Run... cmd)

ipconfig /all

I'll have to get you some of that info when I get back home, but the site is www.clio197.com and I had a quick look in my hosts file late last night and I'm pretty sure the only thing in there was 127.0.0.1 but my memory from 3am is pretty flaky! I'll have to check the ipconfig /all when I get home.

O/T - Got you email at the weekend Jamie, I'll send you a reply tonight, cheers.

DNS looks fine, all 4 dns servers reply with the same info..

It's hosted in the US, but in itself that shouldnt make in inaccessable for you..

it could still be a local DNS issue, your ipconfig /all will shed more light on that...

or they could be firewalling you (or you them!)

Got back from work and fired up the computer and modem and lo and behold the site is working again! However I don't think I've seen the last of the problem as it did this previously...

So, results from the ipconfig /all command....

Ok,

that shows the DNS it's getting is from 192.168.1.1

if you have this issue again, try the following.

Go to 'My Network Places'
right click on your active network session (be it wireless or LAN)
double click TCP/IP Properties
at the bottom, where it says DNS servers, tick the box to specify your own
try

91.151.208.10 (my own DNS server)

It's setup to allow recurvise lookups for just this purpose.

Ok everything, close your browser, and then try again.

Cheers Jamie.

Would I be right in thinking that this would be directing my network to look directly at an external DNS server, rather than taking the path of looking at my network which would then refer it to my ISP?

At the moment, your PC is asking your Router, which is then most likely asking your ISP, which is then most likely asking the 'root'
This was means your PC asks my Nameserver which asks the root directly.

It will help rule out DNS pollution.

I couldn't access the site again this morning so I switched to Jamie's DNS server using the TCP/IP settings as described, and could then access the site fine.

However, I've just got home and I'm greeted with no access again despite the new DNS settings, although as ever I can still access the ftp (which surely has to resolve the domain name?).

This is beginning to get really frustrating now....

If it will FTP but not web, then it's one of two things

a) the web server is fubar'd
b) you're using ntl or some Broadband provider who use cacheing proxy and it's fubar'd

works fine, but clio is such a fun, fun car, but not one that would drive

Thanks for checking that scraggles - no sure why I clicked on the links though when I know it won't work for me! What ISP do you use?

I'm with nildram which I understand has a good reputation so I'd hope the problem isn't with them, although I'll get onto their support and that of my host again to see if I can get a resolution!

do this from a command prompt

ping clio197.com

paste the IP it resolves to..

This is the same IP that another of my domains resolves to (same hosting package) only I can access that one...

[JamieBeeston]

ok, so your DNS works,

that means its either some content filter / phishing filter / proxy server..

try disabling all the above crap on your local pc and see what happens..

also try from a different PC in your house if you have one.
