# Client Name

The client name is the name of the client that is registered on the client's operating system and uniquely identifies the client in the CommCell environment. When a backup or other type of operation is performed, the software looks up and uses the client name.

## Changing a Client Name on the Client Operating System

When you change the client name on the client's operating system, you must also notify the components in the CommCell environment about the change. Additionally, you might need to change the host names of the CommServe, MediaAgent and client computers in one or more of the following scenarios:

- When the CommServe is moved or the hardware is changed to provide a better configuration.

- When a CommCell is migrated and the clients are moved to another CommServe.

- When the domain name associated with the CommCell is changed.

- When a client is moved or hardware changed to provide a better configuration.

Note

You cannot the change the client names of the CommServe, MediaAgent, and client computers using the CommCell Console and Command Center.
