Changing and Updating DNS Servers

[TDanley]

Hi

I'm new to managing the DNS entries on our server. We're a small
company so i'm learning fast.

Basically we have one main server ServerX that all the computers in
our office us for DNS.

The DNS settings under TCP/IP on ServerX I have
192.168.xx.xxx
25.24.xx.xx

192.168.xx.xx is the IP address of serverX
Apparently accourding to our ISP our DNS server 25.24.xx.xx is an old
server.

So I should change that. I did. But I still can't pull up a website
that I know has changed its IP address. For example our site
www.petroleumtransport.com has changed and i can't get the new site to
to come up here at the office but can on remote PCs.

What do I need to do to get our DNS to update?

Someone else set up our DNS entries before.

Thanks

What type of DNS server is at 25.24? Do you host DNS services your self on
the DNS server? I believe that you need to modify a Host A resource record
on your DNS server, if you do no thost DNS, then your ISP needs to make that
change for you

If you are hosting your own inturnal DNS, then you need to setup a forwarder
to your ISP for accessing the internet.

All networks that have their own DNS server, especially if it is am Active
Directory environment, should use only the Networks own internal DNS server,
never an ISP's DNS. An ISP's DNS is highly unlikely to know how to resolve
any resource on you local network.
That said, if you do have AD, and the AD Domain name is
petroleumtransport.com, You need to add or update the record named www, in
that zone with the new IP address. You can then make sure you have
configured a forwarder to your ISP's DNS.
