IIS 8 website

Hello experts,

Set up website called SP02 in IIS 8.
Finally got the bindings correct and found
it is also necessary to add a line to the
hosts.txt file. The line is the IP address and the
website host name.  

A file called contact_b.htm is placed in the directory
that was set as the Physical Path for the web site

So now when the path
http://sp02/contact_b.htm 
is input  in the address box of IE on a
Remote Desktop Connection
session to the server that has the web site on it
the file displays correctly.

Now at my desktop, which is on the same network as
the server, the URL, http://sp02/contact_b.htm, is input in the IE
address box. The result is
'The requested URL "http://sp02/contact_b.htm" cannot be found or is not available.
Please check the spelling or try again later.'

When the URL is tested in Firefox  a box at the bottom of the browser
says "Looking up SP02" then "waiting for www.SP02" then
"http://www.sp02.com/?f" appears in the address box with
an ad that wants to sell me a domain name.

I am pretty sure it is a permissions thing. Have tried making the
folder to which the website is directed has Read permissions for
Everyone but no luck.

How can I get the page to be seen on the LAN?

Thanks.
