Thank you for all your responses.

That solves the resolution question. This  implies that I did not pick 
up the complete scope from DHCP. This is Microsoft DHCP, using named 
spaces quite intensively, is it diferent from UNIX? I mean; if I am only 
picking up part of the DHCP info, then my DHCP client is not acting like 
the Microsoft one... what could be different?
