This could be the cause of my problem (sorry for hijacking the thread). Since 
my install upgraded its self to samba 3.0.23c smbd has refused to start, I am 
wonder whether I might have the same problem you outline above.

My Samba runs on Debian Testing and has worked without a problem until the 
upgrade, now the smbd refuse to start. I did a reinstall of samba and 
everything will work if I start it with the default smb.conf but if I use my 
existing conf file then smbd will refuse to start. Could somebody cast an eye 
over my conf file and tell me if it it the problem that Dale mentions

	workgroup = HOME
	server string = %h server (Samba %v)
	obey pam restrictions = Yes
	passdb backend = tdbsam,
	passwd program = /usr/bin/passwd %u
	passwd chat = *Enter\snew\sUNIX\spassword:* %n\n 
*Retype\snew\sUNIX\spassword:* %n\n .
	syslog = 0
	log file = /var/log/samba/log.%m
	max log size = 1000
	server signing = auto
	preferred master = No
	domain master = No
	panic action = /usr/share/samba/panic-action %d
	invalid users = root

	comment = Home Directories
	invalid users = 
	read only = No
	create mask = 0640
	directory mask = 0750
	browseable = No
