Re: DNS gives UnKnown to nslookup Default Server results

Okay, I'm sort-of blind, but learning quick, when it comes to DNS service
internals. That's why I was looking to have someone lead me.

Under Reverse Lookup Zones I have one item (I believe zone is the correct
terminology) named "10.x.x.x Subnet." Under this item, there are two more
items (Records?), each with the same name, as follows:
Name Type
Data
(same as parent folder) Start of Authority (SOA)
[1],msiohcsbs.msi.local.,hostmaster.msi.local
(same as parent folder) Name Server (NS)
msiohcsbs.msi.local

Is it normal to have only this much under the Reverse Lookup Zones? Should I
delete this zone and then create a reverse lookup zone for subnet 10.0.3.x?
