[Samba] confusing samba log entries

[Bostjan Vilfan]

Hello,

I'm having some trouble using Samba to backup my PC with Lenovo's Rescue and Restore. In the course of analysing potential causes of the problem, I noticed in my Samba server's log (pertaining to my client PC) several "can't do this" or "can't do that" messages. Specifically, here are the messages that appear constantly:

[2009/01/12 11:05:52, 0] auth/auth_util.c:create_builtin_administrators(792)
  create_builtin_administrators: Failed to create Administrators
[2009/01/12 11:05:52, 0] auth/auth_util.c:create_builtin_users(758)
  create_builtin_users: Failed to create Users
[2009/01/12 11:05:52, 1] smbd/service.c:make_connection_snum(1033)
  wwpecker-1 (212.235.188.3) connect to service backup initially as user vilfan (uid=1005, gid=1005) (pid 28844)

My question is What is the cause of the above messages, and how can I eliminate them.
