"Failed to add driver. Operation could not be completed (error 0x00000578)."

[wrdavis]

I installed/configured Core Server 2008 for print services

I am managing it via Print Manager from Vista. I have tried exporting/importing printers from a file as well as adding a driver (any driver) individually from the Add Driver wizard - all fail.

The errors I am receiving are:
"Unable to install [driver name] This Operation is not supported."
Then:
"Failed to add driver. Operation could not be completed (error 0x00000578)."

I can add a TCP/IP printer port manually, just no printer drivers.
I am logged in with a user account that has domain admin privileges and UAC is disabled
I was able to install a print driver to the Windows 2008 Core print server on an XP machine. Also was able to install a print driver from the Vista machine using Printer Management on a Windows 2003 print server. Not sure where this error is coming

I've searched the MS forums/Google with no joy - any help would be appreciated.

The only thing I can think of is UAC causing the problem. Although you have it disabled I'm thinking maybe it really isn't. There was a bug in betas that kept UAC on even when turned off.

Have you tried running the management consle with elevated privs?
