Are you saying the ipconfig /all shows the DNS suffix list with no suffixes
listed?

It is not up to the DNS server to look in any zone. It is up to the client
to search configured suffixes for a host. If the client is not configured
with the child's DNS suffix in the DNS suffix search list, it won't look in
the child zone.

By default the DNS client will devolve the primary DNS suffix, thereby
looking in the parent zone. However, clients using the parent domain as its
Primary DNS suffix has no DNS suffix to devolve, you will have to configure
clients in the parent domain to search the child's DNS suffix as well as the
parent DNS suffix.
Configure parent members with a custom DNS suffix searh list of both the
child an parent DNS suffixes. You can also give the parent members the child
suffix as their connection specific DNS suffix by using option 015 (Domain
name) in DHCP.
