Generally when you see something like '^[' that means the control character
you get when you hold down the control key and hit '['.  Now '^[' is the
escape key. That sounds very suspisious. Someone might accidentally get
that into a file if they were used to using vi and were editing with
a different editor. Perhaps use 'vi -b' on the config file and look
everywhere for a '^['.

Did the version of Samba you are using come with the operating system or
did you build it yourself from source?
