How do you find caching only DNS server?

Caching only DNS servers is a

computer that either has MS Windows Sever 2000, 2003 or 2008

operating system installed on it. Then it has a DNS server role

installed on it (think of it as a plug-in program like ad-blocker

for Firefox). And instead of having a DNS zone (sort of like a

shard network folder that only other severs which have been giving

permission to access the folder can have a copy of it, and inside

are the names address of all the other computers like the white

pages) configured into it, it instead remembers where everyone has

been so that it takes less time for the next time someone else

wants to go to the same place. only problem is that the computer

can never shutdown. Think of it like a Word document in progress

that can be changed and read but the save button is missing so in

the event of a power faller all information will be lost. However

it doesn't need to be managed like DNS zone.
