Serial port don't work in windows 2000

I have a Sunray 2 client, Sunray server software 4.

I'm using the sunray conector (RDP Client) to connect to a windows 2000 server.

The serial port mapping is not working when I connect to windows 2000 but if I connect to windows 2003 the serial port mapping work fine.

Any idea?
