Just about any box that runs fast enough to install a modern Linux
will be fast enough as a dedicated DNS server.
You might try a caching DNS server each of your clients.
When my home ISP had a run of nast DNS problems the users on their
support chat group said Treewalk DNS was the hot tip for a solution.
I put it in and in a year it's worked flawlessly. When the ISP's DNS
was acting up the improvement was dramatic.

On my w2k system it seems to use a wahooping 51K of memory, and the
CPU load has to be modest since it offloads some IP networking when
it's working from cache.
Give it a try on one of your machines. It can't hurt.
