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.
