apache help

i just downloaded apache and i installed it and i get a window i have no idea what to put in

its asking for.....

network domain
server name
administratiors email address

what do i put in here??? do i need to buy a domain name to use this???

thanks in advance

Just fake something for now (eg mypc.invalid) - those values are pretty much only used for displaying error pages. You can change them later in httpd.conf if you get a real domain name.
