There's no simple answer, because there are several ways this can work.
If you have your DNS address set automatically, I assume the setting is
coming from your DHCP server (which could be your router or your ISP or
another computer on your system ... perhaps you know). I'm guessing it
might get reset when your DHCP lease runs out and renews.
If your router is the source, it is in turn getting it from someplace
else, presumably your ISP. You can picture the possibilities -- the
most likely, it seems to me, is that your router isn't properly passing
the information along, but it's also possible that the ISP's server is
overloaded or something and not providing that info when queried.
Frankly, I just set the DNS server IP addresses as fixed parameters on
my machines, because I don't have a huge number of machines to worry
about, and I also don't have to worry about DNS servers that move --
they haven't moved at all since I've been using my current ISP.
You can get your ISP's server addresses from their tech support, or
harvest them (using winipcfg or similar) from your machine settings
while things are working. Most ISPs also have them on their Web site
with other installation information (e.g. the same place they tell you
the identity of their POP server and that kind of stuff).
Hope That Helps.
