I know this has come up before with ZfD4. The workstation import works by looking up the location of the zenwsimport dns entry. In my environment, I want to direct some computers to a different container, and there is a way to override the setting on the local station so that zenwsimport actually points to a different server. I didn't think it involved using the hosts file, I thought there was a registry setting, but I really don't remember. I work in an educational environment and need to be able to have the student PCs in a different container and managed with different policies than my faculty/staff/admin folks.
