Resolving name with ip and intranet setup

Hi all,
I managed to install ISPConfig in my CentOs 5 machine based on "CentOs 5 perfect setup".
NB: I installed centOs using text mode and not GUI
However i'm facing two problems

1. How do i resolve IP address with computer Name. I can only access my machine remotely through ip address and not computer name.
   Here is how i've set it up.
   Computer name: wserver
   Domain: dsm.or.tz
   
   but when i write http://wserver.dsm.or.tz page cannot be displayed. If i use its IP address http://192.168.0.20 things goes perfect.
   
   my /etc/hosts looks like this
   
   Code:

   # Do not remove the following line, or various programs
   # that require network functionality will fail.
   127.0.0.1       localhost.localdomain localhost
   192.168.0.20    wserver.dsm.or.tz wserver
   ::1     localhost6.localdomain6 localhost6
   

   my resolv.conf looks like this...where .3 is my primary AD(windows 2003 Server) and .6 is my secondary AD(2003 server)
   
   Code:

   search dsm.or.tz
   nameserver 192.168.0.3
   nameserver 192.168.0.6
   

   my host.conf
   
   Code:

   order hosts,bind
   

   My /etc/sysconfig/network looks like this
   
   
   Code:

   NETWORKING=yes
   HOSTNAME=wserver
   

   The only problem is resolving name with IP.
   I am within my company network and am trying to test ISPCONFIG inside my company before i move any further. My network uses static IP.
   

1. Second problem is how do i use the same ip address of the machine that i've installed ISPCONFIG to host my website. The problem am facing now is that i get this message "Shared IP Address" when i try to access using its ip address after site setup.

Thanks in advance for any help from you?

 

The problem is that the hostname doesn't exist in DNS:

Code:

server1:~# dig wserver.dsm.or.tz

server1:~#

If you want to use this hostname in your LAN only, then you must create an A record (or CNAME) for it on your internal DNS server(s), and your clients must use this DNS server.

What's in Vhosts_ispconfig.conf, and what's the output of

Code:

ifconfig

?
