We are running NW6 SP3. I have been migrating a ton of printers over to
iPrint/NDPS. The current NDPS modules has a memory leak so we had to
restart the server. Since the last restart 200 printers have been
created and there have been several drivers added to the RMS database.
After the restart several of the printers that delivered with no problem
before are no longer delivering. They start the process however error
out with the following:

Error message: iPrint Driver Install - The specified driver .inf key was
not found in the section.

Error Group: iPrint Driver Install
Error Code: -16

I verified some of the printers and they still have the correct drivers
