[Samba] Default User in netlogon share won't work

[Server Gremlin]

Hi Samba List Users,

    I have a "Default User" folder directly in the [netlogon] share, and 
for some reason new users who don't already have a profile (such as when 
they logon for the first time) refuse to download it and use it as their 
baseline profile.  Instead, they fall back on the "Default User" folder 
on the local machine, or they just can't log on and receive an error 
message if the "Default User" folder doesn't exist on the local machine.

    If I login as root, he DOES download and use the profile, even 
though he receives a Windows error message right after giving his 
credentials that says something about "DETAIL - Access is denied."  This 
has lead me to believe that the problem is permissions based, but I have 
done everything I can think of.  I've done a "chmod -R 777" on the 
entire netlogon share, which naturally includes the "Default User" 
folder.  I've also used the parameter "guest ok = yes" in the [netlogon] 
share config in smb.conf and even set "writable = yes" just for 
giggles.  When I created the profile on my XP machine, I remembered to 
pick my domain name and allow "Everyone" to use the profile.

    I've read every bit of documentation I can find on this subject, and 
I feel like I have a solid understanding of how I'm supposed to set it 
up and how it's supposed to work.  Somehow it just...  won't.  Any 
suggestions?

Thanks everyone,
- SG
