Workstations can't browse one site but server can

    Workstations can't browse one site but server can

    Hello.

    We've got this SBS2003 Standard (no ISA, 2 network cards) with a few
    workstations behind it.

    There is one specific web site that won't open in the browsers of any of the
    workstations. However, the
    site opens OK from the server itself. Both the server itself and the
    workstations can successfully ping
    the destination IP address, so it's not a DNS or IP configuration problem.
    Using the IP address in the
    address bar of the browser produces identical results (OK on the server,
    won't open on the workstations.)

    As far as I can tell, no other site is affected. Google, MSN, Yahoo, etc.,
    all open normally on both
    the server and workstations.

    There's nothing in any event log and restarting the server and workstations
    didn't help.

    We're stumped. Anyone have any ideas?

    Thanks.

    What error message do you get?

    The symptom is strange, as there could be a DNS issue, such as your DNS forwarders,
    if your users can't go there by name, but not finding the IP is weird.

    Care to give us the ip and name? Since they are public you would not be
    violating any confidences, except perhaps your own. <g>

    Hi Brenda,

    Download and run a scan with the SBS 2003 BPA. If it says that EDNS is
    enabled, disablet on the server per the instructions and then try again to
    access the web site from a workstation. (also, fix any other problems the
    BPA finds).

    Re: Workstations can't browse one site but server can

    Here's the site: http://theremodelersnewsletter.com/

    There is no error message. The little progress bar in IE's status bar goes
    about a third of the way over with "Waiting for
    http://theremodelersnewsletter.com/..." It stays there indefinitely until I
    type in another site address, like google.com, or close the browser.

    Re: Workstations can't browse one site but server can

    I ran the BPA and, indeed, EDNS was enabled. I disabled it and also
    corrected these "critical" issues the BPA found:

    Help & Support Service missing
    Receive Side Scaling enabled
    Task Offloading is enabled
    TCP chimney is enabled
    TCPA is enabled

    I then rebooted the server. Sadly, the behavior remains.

    Re: Workstations can't browse one site but server can

    As a test, on one workstation, if you add the website to the Trusted Sites
    in Internet Explorer, does it resolve the issue?

    Re: Workstations can't browse one site but server can

    It could be an MTU size issue, although not in an SBS environment I've
    seen this quite a bit in other setups. Sites look like they will load
    but never do, taking the MTU down to 1450 or around that number on the
    client might be worth a go. I'm not sure what the overhead on the packet
    size of the nat via the SBS server introduces. These problems don't show
    up for a lot of sites, however some do.

    Just something to try.

    You can use the ping command to determine the appropriate setting:

    Re: Workstations can't browse one site but server can

    Hi Brenda -

    I had a similar issue with a client recently, only it was affecting multiple
    sites. Same behavior though - machines could resolve the name successfully
    (so not a DNS issue), but would just sit waiting for a response from the
    site. In the end - it turned out to be an issue with the client's DSL
    modem. Qwest had us change the DSL settings from PPPoE to PPPoA. Modem
    rebooted, and the sites started working for all machines. Was definitely
    one of the weirder issues I've ran in to . . .
