Unable to use printer over network with Server 2003 64Bit

I have a Windows Server 2003 SP2 64bit machine with the magicolor 2430DL connected via a USB port.

I have installed the latest 64bit driver for this operating system and printer.

I have upgraded the firmware to the current software.

When I try to add additional drivers on the server either from the original disk (32bit software) or the latest driver from the web for Windows XP 32bit, a dialogue is displayed saying the driver should be installed remotely.

When I add the printer on a client, using a network printer, and then activate the printer properties I get an error "Function address 0x49a2290 caused a protection fault.

After I click OK, I get an error "The 'KONICA MINOLTA magicolor 2430DL' printer driver is not installed on this computer." Do you want to install the driver now?

NOTE the client does function OK when the printer is attached to a local USB but I want the printer to be on the server.

If I say YES to install the driver and go ahead to install the driver the successful install dialogue appears BUT on continuing I then get the same function address error.

If I then try a test print I get a "Window Explorer had encountered a problem and needs to close." error.
