on 64-bit 2k8 server, trying to add x86 drivers asks for ntprint.inf

I've read the relevant threads, and no one seems to be having my exact problem.

The server is a 64-bit 2008 server with the print role installed.  I can add x64 drivers fine, but when trying to add x86 drivers, I get stuck.  I have tried several HP printers:  LJ2300, 4100, 2420.

Here's the procedure:

Under the Drivers area of Print Management, right click, Add Driver.

Click Next.

Select only x86 architecture.

Choose Have Disk.

Browse to the location of the extracted x86 driver for the printer.

Select printer from list (in this case LJ2420)

Click Next.

Windows prompts with the following:

Install Components from Windows Media

Please provide path to Windows media (x86 processor).

Type the path where the file is located and click OK.

It appears to be looking for ntprint.inf.  I have tried several OS installation CDs - Server 2003, XP, Vista.  None of them are accepted.

Any thoughts?

Thanks!
