(This is because the end-user is not aware of domains or > networks.) 1: Isn't a UFN is just a representation of a Directory Name with a default sequence of attributes. Why is the user searching for the machine ? Presumably because they have been told that some desired service is accessible on it. So the name will have been presented in a form that identifies the attribute types - either explicitly or by default according to some set of rules. 2. By "well-defined subtree" Are you asking for all Organisations or Organisation Units to use the same structure below their level ? Surely not. Interaction of Locality and OU have different "obvious" answers depending on what kind of O you are. 3. On a side issue (and at some risk of pedantry) why are we talking about machines ? A presentation address identifies a *process* (strictly, an application entity that is the projection of an application process into the communications environment), and the process may move from one machine to another. Yes, it makes sense to think of the process as being the machine if you want to login to it, but probably not if you after something with access to a distributed database or the like. service = machine is rather old-fashioned. I may be way off course here, of course. Peter
