What is DNS, and what does it do?

Hi,

On an XP(SP3) machine:

To speed up my machine I clear out the Windows Prefetch folder a couple of
times a week.  In addition I flush the DNS resolver cache at about the same
frequency.  Defragmenting the hard disk is usually the biggest save,
although you might want to consider scheduling a page file defragmentation
at start up.

I use DiskKeeper to schedule a page defrag, but this is a little involved
and you either need to buy the thing or get a 30 day trial.

NB: to flush the DNS click on the 'RUN' icon on the start menu and type the
following between the () exactly:
(ipconfig /flushdns)

You must be logged in as administrator.

Thanks,
