Technical Tip: How to manually add EMS pre-defined hostname

By default, 'Pre-defined hostname' is greyed out and it cannot be modified through the EMS GUI, as shown in the picture below.

For some reason, adding a new hostname to EMS can be done via the following steps:

• Take a VM snapshot of the EMS server for recovery purposes. 
• In the Windows Server, navigate to the directory 'C:\Program Files (x86)\Fortinet\FortiClientEMS\Fcm\fcm'.

• Locate the file settings.py -> Open with Notepad or Notepad++.
• Edit the line below and save it:

PREDEFINED_ALLOWED_HOSTS = ['127.0.0.1','R2D2-kvm72','localhost']

• Reboot the server for it to take effect.
