What does the 'server is busy' message mean in Xmanager?

PROBLEM DESCRIPTION

In Xmanager's detail view list a "(Server is busy)" message appears and fails to connect.

REASON

RESOLUTION

In the gdm.conf file, set the[xdmcp] section with 1, setup DisplaysPerHost as desired, then with the command gdm-restart, refresh gdm(gdm-binary).
