Hmm, looking at the samba-non-working.tat.bz2 logs it looks like the client resets the connection: [2017/08/29 15:08:57.263165, 3] auth/check_samsec.c:399(check_sam_security) check_sam_security: Couldn't find user 'D289397' in passdb.

Samba tries to send its version information but the connection has been already reset by the client! This doesn't really look like a Samba issue if the connection is being reset. I think this is the same as bug #1413484 I guess Win7 requires signing ... *** This bug has been marked as a duplicate of bug 1413484 *** Clearing NEEDINFO since this is closed as Duplicate |
