Sorry, My mistake it didn't fix the problem. (I was running the application from the c:\ drive rather than the share). I am getting exactly the same errors in the log: unix_clean_name [common/config/.root.passwords] [2002/02/21 11:15:44, 4] smbd/open.c:open_file_shared(779) calling open_file with flags=0x0 flags2=0x0 mode=0644 [2002/02/21 11:15:44, 2] smbd/open.c:open_file(216) INSTALL opened file common/config/.root.passwords read=Yes write=No (numopen=1 0) [2002/02/21 11:15:44, 3] smbd/posix_acls.c:unpack_nt_owners(443) unpack_nt_owners: unable to validate owner sid. Any ideas - Anyone? Thanks Tom -----Original Message----- From: Mead, Tom Sent: 21 February 2002 10:35 To: 'David Mulcahy' Cc: 'samba@lists.samba.org' Subject: RE: Big problem with 2.2.X. Thanks very much David - This seems to have done the trick. This configuration option does not appear in SWAT.

Im no expert but i think you have to use nt acl support = no on the share concerned in the smb.conf HTH David I have been using samba 2.0.X for over a year with solaris 2.6 and windows NT4. I have a windows application installed onto a Unix share which is mapped to the NT clients using samba. Everything has worked perfectly with the windows application untill i reciently tried upgrading to a 2.2.X version of Samba. ( I have tried 2.2.2, 2.2.3, 2.2.3a). Now when i try to start the windows application, it crashes when it fails to read one of the applications configuration files on the share called root.passwords. The server that i am testing this on is running Solaris 8, and i have tested this with NT4 and windows 2000 clients.
