Newbie to Samba

[shui at yxepna01.pointsnorth.com]

Hello all,

I'm newbie to Samba.  Please excuse me if the questions sound stupid.  I
have a few questions below and I'd greatly appreciate if someone can
provide me hints
on them.

1.  Samba keeps it own set of password in private/smbpasswd after Samba was
installed.  What's the use of those passwords?  Are they being used to
perform validation if "Password required" is specified in smb.conf for
using a particular service?
2. I believe the samba passwords are different from NIS+ passwords (we're
running Samba server on a Sparc Solaris 2.6 machine with NIS+ installed).
How can users change their Samba password from a Windows 98 client?  I know
they can change it using smbclient on an Unix box but what command should
be used to do the same thing on PC?
3. How can I configure the PC side such that all the necessary services
will be mounted (or shared) upon bootup?  I know I can write a netlogon
script on the Samba server but how can the PC access the script
automatically upon startup?  This is a PC question.  Please excuse me since
I'm not a PC expert.
4. I read from the newsgroup that I can synchronize the NIS and Samba
passwords.  Does anyone have experience synchronizing NIS+ and Samba
passwords?  Again, what command should be issued on the PC side to do that?

Thank you all for your attention.  Your help is greatly appreciated.
