ERROR: 8000006E (the system cannot open the device or file specified)

I'm trying to export search results.  I'm in a Domino environment, but I'd like to export the data to a PST.  when i try to export to an NSF file (Notes Authentication), it creates the database, but the file is only a stub of a database and the query.  If export to a PST (pop3 authentication), I get the same error AND no file is created.  what is missing from the setup that is preventing the NSF file from being properly created, and what is missing that prevents the PST file from being created at all?

Thanks
