[Samba] Samba Server

[root]

Hi 

I work for an NGO in South Africa and am trying to configure a Samba server, 
but I am way out of my depth!  Is there anyone who is willing to be very 
patient and help me with this?

First question:  I have created a user with a password on my Linux server 
under User Manager, and then I have created a share under Samba for that 
user's home directory, but if I try and access it from my windows machine on 
the network it keeps rejecting the password, so therefore I am assuming there 
is something else that I need to do ...  What is it?  I have gone into the 
password section on Samba, but It's not making much sense to me.  Does the 
user have to be created there also, and if so how?  because it doesn't give 
any indication as to whether the user has been created or not and there 
doesn't seem to be any way of seeing anything.

Regards
Wendi
