Problems after change static IP address

[ElpidioValdez]

I have a network with NT 4.0, the server has two network card one for DNS and one for the network. In the morning I change the ip address for the DNS (AT&T demand this).
The server and the ws surf in internet and the server send and receive emails. In the workstations the outlook send the message "Microsoft Exchenge server unavailable" when I make a ping to name server the answer is the old IP address.
If I turn dissable the DNS or the Wins the outlook work but the ws station don't surf.
If you need mor information, please ask me.

There could be a couple of issues here.

1: Easiest: WS's have a HOSTS file on them. Check one of them. If there is a HOSTS. (Not the .sam) file in the windows/system directory, look to see if there is an entry for your Exchange server. Change the IP to the new IP address.

2: If that is not the case, from the NT server, go to your WINS Manager program. (Start - Programs - Admin Tools - WINS Manager) Check your database and your static mappings (Under the Mappings header) If you see any mappings to the old IP address, change the IP address listed.

Did you make sure that the DNS server is now bound to the new IP, You will probably find it is still trying to use the original IP.
