samba - Oct 2001 - Could someone please let me know what these error messages mean a nd if I should be worried

Also, if you know how to fix them please let me know as well :)

In <username>.log:

[2001/10/17 14:50:42, 0] smbd/service.c:make_connection(238)
  <username> (10.1.1.126) couldn't find service form

[2001/10/17 12:15:17, 0] smbd/nttrans.c:call_nt_transact_ioctl(1734)
  call_nt_transact_ioctl: Currently not implemented.

In <machinename>.log

  ifst2 (10.1.1.189) couldn't find service dat

In what I think is winbindd.log but it only shows up as ".log" (if
someone
could explain why this is happening I'd appreciate it as well):

  getgrname_from_group(): could not get domain sid for domain
