We have a NW6.5 SB Server with GW 8.01

This is a Single Server, 1 Domain and 1 PO

We have multiple Internet Domains and it sort of works. But problem with
Duplicate names etc (fugged to get around the limitations of the setup)

Simple NW SB install so all users in the main context - well everything is!

I want to tidy up the system.

My question is

If I create new CONTEXT and setup PO's for each Internet domain + users
under that would that enable me to avoid duplicates
(docs generally talk of single organisation and different departments)

(we have 6 Internet domains - 3 independent companies )
