Applies To: Forefront Threat Management Gateway (TMG). This topic describes how to create a Fully Qualified Domain Name (FQDN) for Forefront TMG in a workgroup. The FQDN is a name used to enable array members and the Enterprise Management Server (EMS) to communicate with each other.
The /etc/hostname file contains the fully qualified domain name of the local host. Thus, the system emu, in the DNS domain cassowary.net, has the fully qualified domain name emu.cassowary.net. Independent of DNS is the local hosts file (/etc/hosts), which is used to list local hostnames and IP addresses. For a network with large numbers of hosts, using the /etc/hosts file is problematic because its values must be updated on every host on the network each time a change is made.
