    Check with your ISP. Only they can tell you if you have the right IP addresses entered for your DNS server.

    in my case it turns out that zonealarm occasionally blocks access to DNS-Servers.

    this problem occured every once in a while and lastet for about 5 minutes, then it all goes back to normal.

    changing zonealarm settings did not bring any relief.

    even 'repairing the network' from the network status dialog resulted in an error

    if youre not using zonealarm, you might have problems that your PC is unable to detect wether its online right now, or not.

    there might be a wrong entry in the settings of internet explorer (even handling settings for other browsers)

    checkout Internet explorer - extras - connection

    you might have a manually entered DNS-server in there somewhere.

    telling how your settings must be depends very much on your networks structure.

    do you have a specific DNS server your ISP asks you to put in some field somewhere ?

    do you dial-up with an adaptor or a modem ?

    too much to checkout here, unsure what to do.

    whatever you do its important that you end all instances of IExplorer and restart it (sometimes even those still in the taskmanager, but not visible on the desktop), just to bring IE to the point finding out that you are online.

    one possibility is that your DNS-cache holds information which is no more accurate. you can flush the DNS-cache (instructions within help section)

    DNS as far as i remember works on port 53, so you should ensure its not blocked in a firewall, or am external router

    but if all does not help ... live with it .. its not a bug, its a feature

    Let me guess, you cant open a web page and the generic error message in IE mentioned that it might be caused by not finding a DNS server...

    I swear you have to be a mind reader sometimes.

    You have a connection issue that could be anything. ping is your friend.

    In DOS type ipconfig /all and see if ya have DNS servers, try to ping them

    try to ping

    call your ISP tech support=) ya got too many things that could be wrong.
