Mac OS tends to change the computer name when switching from network access type, e.g. from cabled network card to wireless network card, resulting in a different Composite host ID (CID), leading to an unavailable NX license.
This can be prevented by assigning a fixed computer name in the files :
Location Filename Value
======== ======== =====
/etc/ hostconfig HOSTNAME = MyNewName
/etc/ hosts 127.0.0.1 LOCALHOST
The "hostconfig" and "hosts" files are to be found in the hidden folder "/etc", in the Finder --> Go-Go to Folder --> /etc, this will display the folder and its contents.
Note : For a simple Server/Client installation (1 user), the computer name can be replaced by "127.0.0.1", but if a Mac is to be used as license server for multiple computers, it needs to have a unique name in the
