    I have got very strange behaviour of my web browsers. I use mostly Mozilla but the same happen with IE7 and Opera9.6 I have no connection with most webpages. However I can connect certforums.co.uk but for example I can not connect to www.msn.com. I use cable virgin broadband.I have got network made of Belkin wired router.I have pinged loopback IP and my network is ok.I have pinged DNS servers too, it is fine as well.
    I have released and renew connection but still problem.I have reflushed DNS still nothing.I have restarted router, modem and PC still the same.
    The problem is that the webbrowser display only certain pages. I have checked firewall too and it is ok.
    Do you think it is Virgin fault or DNS server or maybe any virus in my PC?
    Without internet I can not do much and i am...:cussing

    First thing I would do is delete the browser cache and then do a full virus and spyware scan, then take it from there.

    Have you tried another PC/laptop on your connection?

    Open up a command prompt.

    Type...

    nslookup
    www.msn.com

    Does it resolve ok to an IP address?

    I deleted cache before and run antivirus scan too but nothing.
    I have tried the nslookup www.msn.com and it says:
    ****Can't find server name for address 192.168.2.1 ( my gateway): non existent domain
    ****default servers are not available
    DNS request time out

    In the properties of the LAN connection goto TCP\IP and make the DNS servers static.

    Try the following DNS servers

    208.67.222.222
    208.67.220.220


    If you want to test first then try this.....

    nslookup
    server 208.67.222.222
    www.msn.com

    Does it resolve ok?

    I get......


    Code:
    C:\Users\Sparky>nslookup
    Default Server:  BeBox.config
    Address:  192.168.3.1
    
    > server 208.67.222.222
    Default Server:  resolver1.opendns.com
    Address:  208.67.222.222
    
    > www.msn.com
    Server:  resolver1.opendns.com
    Address:  208.67.222.222

    Server: Unknown

    Weird.

    If you go to nslookup again (just use the default DNS server from your router) does it resolve www.certforums.co.uk ok?

    Virgin's network infrastructure is ****. I regularly experience issues related to upstream DNS. Its usually resolved by changing the modem to a different upstream and rebooting - you might want to try that next time it happens. Touch wood, I haven't experienced a problem for about three months, but when I do, if the change of upstream doesn't fix it I just give up and switch to 3G on my laptop for internet access until its fixed - I can't bear those soul-destroying calls to first line idiots reading from a script.

    I was on Virgin too until I changed to Be, they had some continual DNS issues, I google'd some other DNS servers and added them in, resolved the issue - or, if you ipconfig /flushdns - ipconfig /registerdns it will work for 5-10 minutes :biggrin
