2.11.1 Customizing the RTR Windows NT Service
While starting RTR, the Service looks for the file
directory. On finding the file, the Service executes any RTR commands it may
contain. RTR commands from
From the point of view of the Service, the RTR home directory is found in the
system-level environment variable

For the RTR Service to use it,

the system must be rebooted after the definition of

Because the RTR command server executes under the SYSTEM account,
it cannot be stopped from Task Manager other than by the SYSTEM
account.
2.11.2 Files Created by the RTR Windows NT Service
If RTR is started from the Service rather than via a Command Prompt window,
several files are created in the RTR root directory.

Creation of these files is unconditional; that is, they are created every time RTR
is started or stopped, whether or not they already exist. RTR will thus ignore
