[Samba] XP Problems adding machines "on the fly"

[Tom Skeren]

Having trouble with the add machine script.  Followed the chapter 6 
how-to, but, it fails.  Checking log file for the machine after 
error-RPC call failed on XP box, I find a 101MB log file filled with 
-error must provide name- something to that effect.  Any help would be 
appreciated. smb.conf follows.
