1) Printing
Since rh70 has LPRng I think you should use
printing = lprng
instead of
;   printing = bsd


2) Not up-to-date comments
# Use password server option only with security = server
;   password server = <NT-Server-Name>

This is not true, you have to use that directive with security = domain 
too. If you use "security = domain" you can even use "password server = *".

3) Obsolete comments
;   domain controller = <NT-Domain-Controller-SMBName>
this directive is obsolete/deprecated. Should neve be used.
I suggest you take it out of the smb.conf file.


4) logon pqath
# Where to store roving profiles (only for Win95 and WinNT)
#        %L substitutes for this servers netbios name, %U is username
#        You must uncomment the [Profiles] share below
;   logon path = \\%L\Profiles\%U

Since 2.0.6 samba doesn't send anymore what you put in "logon path" to 
win9x machines, win9x only sees "logon home".
See 2.0.7 release notes and updated DOMAIN.txt

Now win9x machines can only put profiles in the homedir, like they can do 
in an nt4 domain.
So you can
logon home = \\%L\%U\
or
logon home = \\%L\%U\<directory>, ie:
logon home = \\%L\%U\.profile  (hidden)

"net use h: /home" will work now.

If you want backward compatibility you need
logon home = /some/path/outside/homedir
you get the old behavior, and "net use  /home" doesn't work as before.
I think this should be considered deprecated and not mentioned.


5)
"writable" has no effect on printer shares.
