How do I change the Zen Vault Professional default port?
To change the default port, please stop the Zen Vault Professional service in the Services window in the Control Panel. Next, browse to the folder where Zen Vault Professional is installed (the default folder is C:\Program Files\ZenVault Professional\) and open the a5backup.properties file with a text editor. On a new line, add the entry service.port=10001 and replace 10001 with the port number that you want to use. Finally, start the Zen Vault Professional service again (via the Control Panel), open Server Edition and confirm that you can initiate a backup.
