SYMPTOMS
Attempting to set a security descriptor for a communications ports results in error code 1350 (ERROR_NO_SECURITY_ON_OBJECT) being returned to the program that attempted to set the descriptor.



CAUSE
Windows 2000 includes a new device for Plug and Play support in the device stack for the serial device. This device is controlled by the Serenum.sys driver. This driver creates an unnamed device entry that is installed above the serial driver. Because this device does not have a name, Windows does not assign a security descriptor to it.
