# Changing the Host Name of a Client Computer

You can change the host name of a client computer.

## Before You Begin

- Verify that there are no jobs running for the client.

- If you are changing the host name of a proxy client or a client behind a proxy, review the information in Network Considerations for Name Change Operations.

- Verify that the client is online. If you submit the name change request when the client is offline, the name change operation is completed when the client comes online.

## Procedure

1. Update the name of the client or MediaAgent computer operating system with a new name, and then verify the following:

   - Verify that the computer is available in the network with the new name. (DNS lookup or other name resolution facilities are appropriately configured to resolve the new name of the computer.)

   - Use ping (or other network connectivity utilities) to verify that the computer with the new name is accessible. Also verify that other computers in the network are accessible to the computer with the new name.

   - Verify that all applications running on the computer, for example, SQL server, Exchange, Server, and Oracle database, function with the new name.

     - To rename a Windows computer that hosts a stand-alone instance of SQL Server, see http://msdn.microsoft.com/en-us/library/ms143799.aspx.

     - To rename a Linux computer that hosts a stand-alone instance of SQL Server, see Renaming a Linux SQL Server Computer.

2. From the CommCell Browser, right-click the client or MediaAgent whose name was changed, and then click Properties.

   The properties dialog box appears.

3. In the Client Name section of the General tab, in the Host Name field, update the host name with the new name.

4. Click OK.

   The services on the client or MediaAgent are automatically restarted. For clients that contain the File Archiver for Windows/Unix agent or the One Pass agent, it is important that services are restarted after the name change. This ensures that stub recalls from these clients function correctly.
