Hi all,

I was wondering why do we need to harden Windows server 2003 by
applying rules like:
1.Remove any unneeded Services
2.Close unneeded ports
3.Rename Administrator account
4.Prevent users from installing printer drivers
5.Restrict CD-ROM and floppy access to locally logged-on user only

... and many many more

why are we doing so ?????
and what is the main problem with the default installations.

i tried searching the net but all what i found is that what to do, but
not why do we do each step and what is the effect of not applying it.

thanks for ur help and time
