The ReadOnly property determines if the server should only
allow read-only access to files by default, changing the default
permissions granted to authenticated users. If this property is set to
True, commands that are used to create, delete or modify files
on the server will be disabled by default.
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.
