Answer:
You must import the NPS configurations, then manually cnfigure the SQL Server Logging on the target machine.
Step-by-step explanation:
The SQL Server Logging settings are not in anyway exported. If the SQL Server Logging was designed on the root machine, the a manually configure of SQL Server Logging has to be done on the target machine after the NPS configurations must have been imported.
Although administrator rights is needed at least to import and export NPS settings and configurations, while that isn’t the issue in this case. NPS configurations are moved to a XML file that is non-encrypted by default. There is no wizard or tool whatsoever to export or import the configuration files.
