In an environment where the admin server belongs to the domain and DHCP Server is installed, some of the application process functions are not started unless DHCP Server is authorized. If the [Request] tab is opened while some of the application process functions are not running, the error screen "500 Internal Server Error" or "HTTP Status 404" will be displayed.
Authorize DHCP Server and then restart the OS of the admin server.
For details on authorization of DHCP Server, refer to "2.1.1.2 Software Preparation and Checks" in the "Setup Guide CE".
