samba - Jan 2002 - redhat 7.2 and \\serrver is not accessible

I have been going nuts for two days, and now I have peanut butter!
I used to be able to setup a samba server on redhat 7.1 in about 11 
clicks via webin. Now with 7.2 no luck.
It turns out that by default when you install redhat 7.2 it sets up the 
firewall services for nothing in-nothing out. Hence I can ping the 
samba server ip, and it turns up on my winnt4 box, but is not 
accessible. I deactivate the firewall and bingo!
All my directories and printers.
Try it if you have a similar problem.

Hi palls

How can I syncronize LINUX and SAMBA passwords?
I've tried to configure my smb.conf like this:

[global]
    encrypt passwords = no
    smb passwrd file = /usr/local/private/smbpasswd
    unix password file sync = yes
    passwd program - changepass %u

But doesn't works.
When I type: # passwd user
The programa only change the linux local password.

Thanks.
