Hi
for your first Question
From your station check how your dns server resolve the name using
>nslookup win-oql2facn6h8
You should receive the ip address for the server which is accessed by your browser
2. when you create a web app in shp, you define the tcp port
After creating that web app you should create a site collection, which will be the root web site
To access that site, you should use
http://ip_address:tcp_port
to use a name server instead of IP address,
first you should configure your DNS server, so each client PC, could resolve the name with the IP address
and second , configure AAM in SHP to make corelation between the default zone ( which contain the tcp port ) and an intarnet zone which should contain your name_server
