[Samba] Failed to get GUID / failed to construct printer info level 7 - WERR_BADFILE

[Devin A. Bougie]

We have about 72 printers served from cups to Windows clients using samba.  Point and print works for all of them except 4.   When trying to connect to these printers, the Windows computer just says "Windows cannot connect to the printer.  Operation failed with error 0x00000002."

And in the samba logs for that system, I see the following for each queue that has problems.
------
[2015/03/12 15:52:55.729435,  0] printing/nt_printing_ads.c:116(nt_printer_guid_get)
 Failed to get GUID for printer w229_xrx_7800_simplex
[2015/03/12 15:52:55.729642,  0] rpc_server/spoolss/srv_spoolss_nt.c:4835(_spoolss_GetPrinter)
 _spoolss_GetPrinter: failed to construct printer info level 7 - WERR_BADFILE
------

A cupsaddsmb for that printer did not help, and neither did deleting the printer from cups and creating a new one.  A brand new printer in cups with a different name does work, however.  We're currently running the default cups and samba ( 3.6.23 ) on EL6, and our smb.conf is below.

For what it's worth, this seems identical to https://lists.samba.org/archive/samba/2014-April/180409.html

Any suggestions would be greatly appreciated.

Many thanks,
Devin
