The Restricted property determines if the server should be
initialized in a restricted mode that isolates the server and limits
the ability for clients to access files on the host system. If this
property is set to True, all file transfers are limited to the
user's home directory and certain site-specific commands are disabled.
This is recommended for general purpose applications designed to
accept connections from clients over the Internet. This property value
is only meaningful if the MultiUser property has also been set
Attempting to change the value of this property after the server
has started will cause an exception to be raised. To change this
property value, you must first call the Stop
method which will terminate all active client connections.
The default value for this property is False.
