[Samba] weird Windows profile creation

[Christopher Perry]

It seems weird. On 75% of my machines, it creates accounts as:
c:\documents and settings\username

on 25% of the machines, it creates them as:
c:\docments and settings\username.DOMAINNAME

These are fresh machines, so it's unclear to me where this behavior 
stems from. We're not using roaming profiles.

Does anyone have any idea as to why this happens?

thanks
Chris
