Subject: DCOM RPC exploit failed

Hi

With the Portuguese version of Windows XP using the 
offset from Windows XP SP1 english something different 
occurs. A window with a 30 seconds countdown and these 
senteces appears:

"You are not a valid administrator. Your computer will 
be powered off"

pretty disturbing. Finding the right offset will lead 
this exploit to be a new DoS tool with pratically no 
changes.
