    hmm; lookup is failing and you can't even reach your own IP address - - not good

    Be sure to use an admin login and then (start->run->cmd) enter netsh winsock reset

    download http://download.bleepingcomputer.com/spyware/lspfix.zip
    and run that too.

    reboot and get the IPCONFIG /ALL data and the NSLOOKUP google.com. too

    the dns provided by your ISP is not operational as
    it doesn't answer PING and
    that address is registered correctly to
    I can penetrate only two levels(#17 & #18) into that domain before there's problems internally with flowtrinidad.com
    One last attempt try nslookup google.com. 8.8.8.8
    the third parameter is the google dns and causes your system to use the google dns just for this time

    using that last example, you might also try accessing the OpenDNS servers
    # 208.67.222.222 (resolver1.opendns.com)
    # 208.67.220.220 (resolver2.opendns.com)

    that looks good - - let's put the OpenDSN server addresses into the TCP settings manually as
    • 208.67.222.222
    • 208.67.222.220

    then run these
    ipconfig /flushdns
    net stop "dns client"
    net start "dns client"


    disconnect the system from the router/modem; wait 30 secs and then reconnect

    nslookup google.com. should respond with
    and a tracert google.com should look nearly like
    and your browser should now access http : // google.com/
    just fine

    Sorry to disappoint but the results don't look good:

    C:\Windows\system32>nslookup google.com.
    DNS request timed out.
    timeout was 2 seconds.
    Server: UnKnown
    Address: 208.67.222.222

    DNS request timed out.
    timeout was 2 seconds.
    *** Request to UnKnown timed-out

    C:\Windows\system32>tracert google.com

    Tracing route to google.com [74.125.229.49]
    over a maximum of 30 hops:

    1 * * Client-PC.flowtrinidad.com [190.213.84.86] reports: Dest
    ination host unreachable.

    Trace complete.

    Just the last test for OpenDNS was just fine
    but even worse, is the status of YOUR PC
    I firmly believe the DNS setting is fine and the problem is in your PC.

    Just for clarification, if you're having such a time with this system, how is it you can
    access Techspot to post these results?

    Between the dns and the timeout errors I can access websites, although the speed is very limited. I sit on this page and f5 every so often.

    Until recently, I've been using a desktop machine on this connection and I've been having the same issues for over a month. Also, I occasionally use this laptop on another internet connection with the same ISP without any problems. On those occasions though, I used wi-fi.

    google for an updated driver for your Marvell Yukon 88E8040

    Updated my driver but sadly, no improvement. Pinging google.com still results in lost packets and tracert still reports "Destination host unreachable".

    man - - I'm at the end of my rope. Your system has issues and I can only guess it's a virus or trojan.

    Don't sweat it. Thanks for all the help anyway. I'll do a system scan and get back to you.

    AVG and Spybot S&D don't show any infections.

    I think the problem is due to Dell's remote access utility. When I disabled IPv6 with the Microsoft fix, upon restart I got a message saying the Advanced Network Service wasn't running and the utility could not be started. For the duration of that session my internet worked fine. Today I got the same message and my internet seems fine for now.

    I found that a few people had connectivity issues when this service is running. Is it's okay to disable this service permanently, and if so, how?

    my goodness!

    To control Services you need to get a command prompt,
    then enter runas /user:xxx cmd
    were xxx is a login with admin privileges

    in the new window, enter services.msc

    the list is in Name Order, so scroll to Advanced Network Service
    double click the name and STOP it.
    change the Startup type to DISABLE.

    click apply, click ok

    I have had this problem for a few weeks and I carefully worked through all possible reasons ,, i went on lots of trouble-shooting sites to research their answers , I HAVE SOLVED THIS PROBLEM FOR ME ANYWAY, :) the answer is ,,,,,, (drum roll here..lol) make double sure there are no updates waiting to be installed on your machine, pending updates will cause this problem.
    IT was black and white for me, I was struggling to get on the internet at all . then 10 mins later after I updated the problem was totally gone,and i was back to my speedy internet as normal ,I know this sounds unlikely compared to all the technical answers above and elsewhere, but please try it and post back , after all it cant do any harm can it?
