samba - Jan 2005 - "Access Denied" from Windows

I've actually had this configuration in the past, but I have no recollection

of how I managed to make it happen.

I have a small NT 4.0 domain, and have just built a Red Hat 9 machine, which

I would like to make a member of the domain.  My networking is okay -- I can

ping the Linux machine from any of my windows boxes, and vice versa.

In Linux, I can see all of my domain shares, and can acces them--only 
problem is that it's asking me for a windows password to access.
>From the Windows side, I can see the machine in my Network Neighborhood, but
when I click on the machine, I'm asked for a name and password.  When I 
enter Root/root-password, it redisplays the same login screen, replacing the

user name "root" with "MY_WIN_DOMAIN_NAME\root.

In the NT Server Administrator, I've added the Linux machine as a member, 
but when I double-click on the name, it tells me "Access Denied".

Any help would be greatly appreciated.  I have the sense that I'm pretty 
close here.  The following is a list of my Samba settings:

Thanks
