[Samba] Samba share as document root in Windows XP

[Jonas Höglund]

I have a IIS 5 web server running on a Windows XP box. I want to use  
a Samba share (on a Mac OSX machine) as the www root (document root),  
but get access problems when I try doing so. I think my problem is  
related to this previous question I found in the list archives, but I  
couldn't find any answers. http://www.mail-archive.com/ 
samba at lists.samba.org/msg05340.html

I also found this at Microsoft's Knowledge Base, but I can't get it  
right. http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q256322

In regards to the Microsoft article I have four questions.
1. Is this relevant for Windows XP?
2. What's the Regedit key in XP? Is it MACHINE/System/ 
CurrentControlSet/Services/LanmanWorkstation/Parameters/ 
EnablePlainTextPasswor as suggested here http://lists.samba.org/ 
archive/samba/2003-February/061643.html
3. Microsoft says "Map a drive letter to \\<servername>\iisroot using  
'root' and "password". What do they mean with "root". Samba "root",  
Mac OSX "root"...???

Thanks in advance!
