Verify that the hosts file is located in the following folder:
If you are running a Name Server, verify that the hosts file is on the Name Server and that network software is configured to access the Name Server.
The Teradata Tools and Utilities software uses generic TCP/IP GetHostByName services.
If not running a Name Server, verify the hosts file contains a list of all systems on the LAN that can be accessed.
The Teradata Database must be identified in this file if a system is going to communicate with it. A hosts file exists on each computer system in the network.
