Hostname Resolution Problems
Hostname resolution is a very common problem in a Data Protector
environment. It means that host A is unable to communicate with host B.
The table below shows Data Protector components and how they should
communicate within the Data Protector environment. Communication
among hosts means that host A in the table should resolve host B by its
fully qualified domain name (FQDN). Resolving a host means that host A
can interpret the FQDN and determine its IP address.
