    Ok i had an update for Zone alarm today.. everything was fine until then. After the pdate i find i have no net connection at all. I can connect on my LAN but i cannot get an internet connection from the one machine with the update on it. So thinking that zone labs had screwed my settings i uninstalled it.... Well no luck still no net!
    Pinged the router.. fine no poblems, can connec to other pc on LAN (one im using now) but just no net.

    So i ring my ISP. Do what they tell me. try to reset the DNS on the PC. They give me a new DNS address to try. That all pings fine but still no net!

    So what have they decided? That zonelabs has screwed my TCI/IP settings in windows some how mesing the DNS up. Solution? do a system restore or windows repair on the comp.

    So anyoe got another idea to try before i do that?

    I've heard from others that ZoneAlarm can do this - but not experienced it myself.

    Can you ping anywhere on the 'net with IP rather than a name?

    Did they get you to do "netsh int ip reset"?

    What does the output of ipconfig /all look like?

    So many questions...

    but before you edited your post, it said this:

    that's an ipv6 address. i mean, you posted it yourself, and i'm sure you didn't make it up, and neither did i. hence my question, have you been playing with ipv6?

    Er - no - I asked if you could ping places on the 'net with IP, not FQDN. Try it and see...

    If you can ping the router - but nothing beyond then the router is the problem!

    i wasn't going to reply anymore, but i do want to point out that the dns servers displayed in your ipconfig (192.106.56.6 and 192.106.33.3) seem to be located in italy, and do not respond when i try to contact them from here.

    You could check that the router has no IP filtering features i.e. to control internet access via IP. also some routers allow you to enforce Zonealarm security features (as long as Zonealarm is running on a LAN PC.

    Other than that have you done:

    ipconfig /release
    ipconfig /renew
    ipconfig /flushdns
    ipconfig /registerdns

    In that order

    You could always delete your current DNS setup and start again from scratch.

    EDIT: Just seen d's post, and I must admit I did wonder why your ipconfig results were showing external DNS servers, at home my results only point to my internal DNS server, if that can't resolve the hostname it then looks outside the LAN, my router only displays external DNS address's

    Nelix, i've tried all those switches....
    for the 1st 2 i get message.....
    The operation has failed as no adaptor is in the state possible forthis operation

    Flusdns says...
    Successfully flushed DNS resolver cache

    and register DNS seems to have worked too....

    My current Ipconfig /all shows

    DHCP eneabled....No
    Ip address........192.168.1.3
    subnet mask....255.255.255.0
    default gatewa .....192.168.1.1
    DNS Servers........192.168.56.6
    .........192.168.33.3 these 2 addys were given to me by my ISP over the phone an hour ago

    However on the working PC it shows taht DHCP is enabled as is Auto config. And teh DNS server address is that of the router. Ans shows teh DHCP server being the same.. SO is it DHCP tahts the problem?

    Im close to reinstalling windos due to all this!!

    If you have a DHCP server configured in the router then you should enable the DHCP client in the machine.

    On 'properties' for TCP/IP set 'get IP auto' and 'get DNS auto'

    Please can you show the *full* output from ipconfig /all now - it's very hard to diagnose when you leave large lumps out!

    To reset TCP/IP back to default the usual command is "netsh int ip reset".

    First - to make life easier and avoid lots of typing - you can redirect the output of ipconfig to a file and copy the file here! :biggrin

    Now - on the 'advanced' button - IP settings tab under TCP/IP properties there should be no 'hard set' value entered - it should be automatic.

    In a CMD box do 'ipconfig /release', followed by 'ipconfig /renew'

    Then check ipconfig /all again.

    Er - this goes back to MSDOS! :p

    In this case: ipconfig /all > info.txt

    For use on limited size windows you can use the pipe symbol:

    ipconfig /all | more
