Are there any errors in the Event logs of the DNS servers, or any servers at
all?
Are these machines responding to queries from the Internet or are they just
used for your internal AD structure?

Try using Quest's Spotlight on Windows. Download the 30 day trial and
install it on a machine other than the DNS servers and watch the DNS server
performance thru it. You can log the stuff and find out at what time they
drop offline and coorelate that to what in your Event logs or anything else
happening on the network.
