    I upgraded by VISTA August CTP installation to RC1. The upgrade was
    successful except one major problem. I can not access most of the websites. A
    few websites load fine but the others return with an error" website not
    found".
    I tried using IE and Opera and the behavior is the same.
    Please help.

    In that case the problem involves your OS and its networking
    more than it does IE7. E.g. it could indicate a performance
    problem with your DNS. At least that's the first thing that I would
    check. If that's all it is you may be able to work around it by testing
    the necessary lookups and caching them manually (e.g. via ping -n 1
    in a cmd window).


    Give a specific site that you are having trouble with
    for people to work on as an example.

    Exactly the same problem here.

    On a dual-boot (seperate drives) install of RC1 some websites (
    such as www.microsoft.com, www.wired.com, www.tomshardware.co.uk for
    example, all work without fail.

    Others such as www.google.com, www.blogspot.com, go.microsoft.com and many,
    many more wont load at all and give the usual "page not found" error.

    On the connection I have there is NO caching done so I know its not old
    pages, I can even ping/tracert all the sites fine. All the other systems on
    my network, inculding booting into XP on my main system, dont have this
    problem at all.

    The router its all being run through is a D-Link DSL-G604T. Sorry I dont
    have a solution but thought a few more details might help.

    Yeah, the same problem, I can't even activate the windows, because I
    always get error cannot connet to the server :(

    It's very strange that just pages are working while the other aren't

  6. As long as the ping command is showing you a valid lookup
    (e.g. not some other IP address which happens to respond to pings)
    you may assume that your DNS lookup phase of the connection
    request is working correctly. I would try checking that assumption by using
    nslookup, although if the lookup by your DNS server is bad the only way you
    will know that is by seeing that it is different from someone else's which works.

    However, since ping really doesn't prove that you can connect to an HTTP
    server at that address a better test would be using telnet 80.
    E.g. if that doesn't at least clear the screen you would have a clearer
    idea of what was wrong.

    Also, that allows you to try reproducing some of what an IE request would
    generate. For example, I just entered this in a cmd window:

    telnet go.microsoft.com 80

    The screen cleared and I tried typing

    GET /

    That's GET followed by <space><slash><Enter> (those 3 characters only).
    By default telnet has localecho off so I don't see my typing.

    Often when I do that the host server accepts the command
    as if it was a HTTP 1.0 request so I don't have to do any more than that.

    In this case, the host server apparently assumed HTTP 1.1
    (e.g. there was no immediate response) so I also entered:

    Host: go.microsoft.com

    Again, I was typing blindly because of localecho being off.

    That still wasn't good enough for it; so I pressed Enter again.

    Here is what the final response was:

    <example>
    HTTP/1.1 302 Found
    Date: Sat, 16 Sep 2006 13:39:40 GMT
    Server: Microsoft-IIS/6.0
    X-Powered-By: ASP.NET
    X-AspNet-Version: 2.0.50727
    Location: http://search.microsoft.com
    Cache-Control: private
    Expires: Sat, 16 Sep 2006 13:38:40 GMT
    Content-Type: text/html; charset=utf-8
    Content-Length: 144
    Via: 1.1 Application and Content Networking System Software 5.3.7
    Connection: Close

    <html><head><title>Object moved</title></head><body>
    <h2>Object moved to <a href="http://search.microsoft.com">here</a>.</h2>
    </body></html>
    </example>


    Clearly the HTTP/1.1 guess worked. If necessary I could also
    have been more explicit with my request and entered

    GET / HTTP/1.1

    What I want to show you though is the immediate redirect.
    E.g. if that was happening with your instance of the request by IE
    and you were having a DNS problem with search.microsoft.com
    unless you started taking more detailed diagnostics you would see exactly
    the same symptom as if you couldn't find an address for the original
    site name. IOW your ping -n 1 go.microsoft.com really wouldn't be
    proving much about the nature of your problem with that site name.


    Yes. More details are necessary, using a specific example.

    A better diagnostic may be to try using FiddlerTool to trace an actual
    request and its response. FiddlerTool also has its own message to
    indicate if there is really a problem with a DNS lookup which also
    may help focus your symptom description.

    If that doesn't work (e.g. perhaps the site would object to the use of
    a proxy) you could alternatively (with the possibility of capturing
    even more details) use netcap and Ethereal to capture and format
    a full TCP packet trace.

    singh napsal(a):
    I did some experiments with very interesting result.
    1) without proxy
    IE: Able to connect to just a few addresses (microsoft.com, etc)
    Firefox: the same

    2) with http proxy
    IE: still the same
    Firefox: Now I can connect to every page.

    Isn't it strange? It looks like something in vista blocks connection to
    specified IP adresses :(

    Folks,
    Finally I was able to figure out a solution.
    It has to do with my router. Many of the older routers do not work well with
    the Vista's new TCP/IP stack implementation.
    I tried a different router and the problem dissappeared. Of course you could
    try upgrading the firmware for your router.
    Good luck to all of you.

    Folks,
    The problem has to do with incompatibility between some of the old routers
    and Vista's new TCP/IP stack implementation.
    There are are 2 possible solution. You could try upgrading your router's
    firmware or try a different/newer router.
    I tried a different router and I have no problems anymore. Everything works
    perfectly fine.

    I followed your advice and I upgraded firmware of my wifi router to
    newest version (from summer of last year) and it's now even worse - I
    can't connect to any website :( Ping is ok, tracert as well, but I
    connecting to any port fails (I tried msn,irc and http). What has
    Microsoft changed in IPv4 protocol??

    I have the same trouble. For example, go.microsoft.com and www.google.com
    returns "Internet Explorer cannot display the webpage" while other sites show
    up w/o any problem. I also couldn't activate my installation, probably for
    the same reason. All this only on RC1, didn't have that on previous Beta2 or
    current XP on same machine.

    I have the same problem, and it occurs whether or not I am plugged into the
    router or directly into my cable modem. So, I don't think a new router will
    solve my problem. :)

    It also doesn't appear to be related to DNS, the correct IP addresses for
    each page come up on the bottom of IE7, the page just doesn't load.

    Anyways, I am running out of ideas for things on my end that could be the
    problem. I played with the firewall, played with the cable modem. Things
    still work in xp . . . so it has to be related to Vista (maybe the routers my
    ISP uses? or the cable modem itself?). If anybody else has an idea to try I
    am game to see what I can do.

    Hi...


    I am from Brazil and have the same problem.
    The DNS of my provider is 201.10.1.2 and in my computer usin windows XP it
    work but in windos Vista RC1 no. I try ping this address in command prompt
    but he don't reply.... Also i create a inbound and outboun rules in Windows
    Firewall to private and public networks and nothing. I try turn off the
    firewall too, but with no success.
    For information, my adsl modem (running at 600Kbp/s) is a DSL500G in router
    mode.

    I think the next step is come back to XP.... (lol)

    Thank's

    The problem seems to be in Vista's Marvell Yukon NIC driver. I switched to my
    second NIC (Realtek RTL8139/810x) and now everything works perfectly.

    So I woke up this morning and tried to see what info I could find on network
    cards and I found a solution that seems to work for me. Here is the info I
    found.

    <<I had the same problem but I found a solution that worked for me. You have
    <<to go into device manager and open the properties tab of your yukon nic
    card.
    << Then click on advanced...then make sure the IPV4 checksum offload is
    <<'disabled' then make sure the TCP checksum offload IPV4 is 'disabled' and
    the
    <<UDP checksum offload IPV4 is 'disabled' and you should be all set.

    <<Mark

    My problem was fixed with just the TCP checksum offload IPV4 disabled. So,
    if you have the Yukon nic chipset you might find this useful.

    Cheers,

    This one gave me probs as well , but it wasnt the site coding that caused it
    I have a Marvell Yukon eternet controller , changed the driver to their
    Vista Beta driver (on the their site) and now its working fine.
    This problem could cause a lot of probs if its not corrected before Vista
    goes public
