Where does the error occur?  On your machine or the DNS machine?  If
it is your machine you could try adding more nameserver entries in
/etc/resolv.conf even if you have to point them to the same DNS server.

I'd try to fix the network problem first.  DNS uses UDP, so if you
are overloaded or dropping packets the answers can be dropped.  You
can work around it by doing more retries but you really should not
be dropping the answers in the first place.   You could run a DNS
server on your own machine configured to use the local DNS server
as a fowarder but unless you have a huge amount of traffic you
should not need that.
