Solved

Web Page not loading, click again and it does.

Tried this in 4 browsers, firefox/IE/netscape/safari.
As an example, if i goto google and type in a search, i get my list of links up. If I then click a link, it'll wait 5 seconds or so and return a message saying the page could not be found. If i click ok, then the same link, it loads instantly. This does it all the time and is very frustrating!

Anyone have a clue? :/

Thanks

    Sounds like you're using some kind of transparent cache, and it's having problems.

    I'd do a search on your ISP name and transprarent proxy or transparent cache, and see if it comes up with anything.

    You can also try pingning the web site first.

    If this cures the problem, then it sounds more like a dns issue.

    Does it happen with all sites, or just some.

    Can you make it happen on a local page?

    It's definitely something to do with the routing on your network rather than the machines / software.

    Run a ping and traceroute on a remote IP / web address (Utilities - Network Utility) and let us know the results.

    Do the Macs obtain an IP via DHCP or are they static?

    DHCP from a Dlink Router. It worked fine for a few weeks, and its only recently been going wrong.

    How many machines connect through this router? I mean is it others apart from the Macs?

    Okay, run pathping to the same address as before from a Windows command line so we can get a comparison between the Macs and the PCs

    Hmm... no tell-tale signs there at all to be honest.

    Try manually specifying the DNS server addresses in Network Preferences and see if that has any effect. I can't see why the PCs would apparently not have a problem while the Macs do. It's very bizarre.

    can you please post the contents of /etc/resolv.conf from a mac, and the results of ipconfig /all from a windows machine please.

    I still think it's a network thing, and I still think it's dns/router based.

    Another thing, is to try a ping -t from a windows machine to one of the affected web sites, same from mac.


    See if the TTL varies wildly.

    This is about right by the way, if it were

    Then it would show a routing problem somewhere.
