Hi, Bill -
Sounds like a couple of slow DNS servers to me.
Try this -
Next time you have this problem, open a command prompt
window, type 'ipconfig /flushdns' (no quotes) and smack
the enter key.
If this solves your problem (and if your machine isn't a
member of a Win2k or Win2k3 domain), open the services
console and stop then disable the DNS Client service.
You can hit the services console several different ways,
but my favorite is to just type 'services.msc' into a Run
dialog box: Start --> Run --> 'services.msc' --> OK
What's apparently happening is your ISP's DNS servers are
a bit slow and the DNS Client service is removing them
from the list of available DNS servers - if they're *all*
a bit slow this can leave you with no DNS servers in the
list. Anyway, the DNS Client service is only required if
your machine is a member of a Win2k or Win2k3 domain.
Hope this helps -
