Everything seems to be working , though I don't quit know what to do with it all

My question is about the DNS Aliases. The only alias that actually works is my router. The rest seem to point nowhere.
the page I get to is always "The page you were looking for doesn't exist."
I admit I don't fully understand this but my thought would be that the link
Name http://books
IP Address 192.168.1.10
should take me to the same share that works if I go to
\\hda\Books
(file://hda/Books/)
But it does not.
Some clarification would be appreciated. All this is on my internal network, the Amahi server is DNS and DHCP host.
Regards,
