Change the names or IP addresses of servers
Ensure the new server name is updated for client PCs
You must ensure that when you change the name of any server with Contact
Center Manager Administration clients, the HOSTS file on all of the client PCs
is updated to reflect the new name.
Updating the HOSTS file
If you have a Domain Name Service (DNS) server for name resolution, you need
not update the HOSTS file for name resolution and you can proceed with
"Updating client PC browsers and shared folders" on page 1501.
ATTENTION
1 On the client PC, browse to the HOSTS file provided with the Windows
Server 2003 installation in the following directory:
<x>:\Windows\system32\drivers\etc
2 Right-click the HOSTS file and open the file with a text editor (for example,
Notepad) to modify the host tables.
Result: The HOSTS file appears in the text editor. The HOSTS file consists
of a list of IP addresses followed by a server name.
3 Update the file to reflect the new name of the Contact Center Manager
Administration server.
If you do not see a server name for the Contact Center Manager Server
listed in the HOSTS file, a DNS server is configured in your network for
name resolution. You do not need to update the HOSTS file.
4 Click File > Save to save your changes.
Save the file without an extension so that your system recognizes the
changes.
Result: The system automatically reads the new settings.
5 Close all windows to complete the procedure.
