Maintaining accesses Remote Name Server Database. Allows to add NameBindings, change them, remove them and resolve NameBindings.
Manages a Naming Service for a remote name space which includes bindings for net_local naming context. All strings are stored in wide character format. A Name Binding consists of a name (that's the key), a value string and an optional type string (no wide chars).
