SYMPTOMS
The Component Object Model (COM) ports that you created during the installation of a multiple-port serial adapter do not start, and they are listed in Device Manager with the following error message:
Code 19 - Your registry might be corrupted.
CAUSE
This behavior can occur because many virtual COM ports that are hosted by this type of hardware rely on the standard serial port driver (Serial.sys) that is included with Windows 2000. This driver, however, can start only if there are hardware COM ports that require the driver.
RESOLUTION
To work around this behavior, enable at least one COM port in the basic input/output system (BIOS) so that the Serial.sys file can load properly.
STATUS
This behavior is by design.
MORE INFORMATION
Event Viewer does not display an error message that indicates that the serial driver has not loaded because some computers do not have built-in COM ports. If you change the
ErrorControl
value in the registry for the serial driver to
0x1
, a warning is displayed that indicates that there are no devices that require the driver.
In Device Manager, on the
View
menu, click
Display Hidden Devices
to observe whether or not the serial driver has loaded.
