hi, I use samba 4.1.11 with bind_dlz on centos6.5. Everything works fine but a couple of days there were messages log.samba. [2014/09/12 12: 04: 48.842136, 1] ../librpc/ndr/ndr.c:463(ndr_pull_error) ndr_pull_error (9): BAD NAME NBT component [2014/09/12 12: 04: 50.948141, 1] ../librpc/ndr/ndr.c:463(ndr_pull_error) ndr_pull_error (9): BAD NAME NBT component [2014/09/12 12: 20: 18.914821, 1] ../librpc/ndr/ndr.c:463(ndr_pull_error) ndr_pull_error (9): BAD NAME NBT component [2014/09/12 12: 20: 21.020747, 1] ../librpc/ndr/ndr.c:463(ndr_pull_error) ndr_pull_error (9): BAD NAME NBT component [2014/09/13 02: 45: 26.555948, 1] ../librpc/ndr/ndr.c:463(ndr_pull_error) ndr_pull_error (9): BAD NAME NBT component I do not know what may be related. Samba is working fine. Do you know what this could be the reason? Regards ?ukasz
