Can't create a PTR record in DNS Manager

I just created a new forward lookup zone. I right-clicked it and clicked New Host (A or AAAA), filled in a name and an IP address, and checked the "Create associated pointer (PTR) record"  and got a message saying "Warning: the associated pointer (PTR) record cannot be created, probably because the referenced reverse lookup zone cannot be found". Can anyone tell me how to resolve this problem?  The Host record was created fine but I'm wondering if that message is something I should worry about. (I chose the "Create PTR record" option because I'm following steps in a book; so I don't really understand what it means.) Thanks in advance.

You need to create the appropriate reverse lookup zone as well for the PTR record:

To add a reverse lookup zone, you have to right click on the REVERSE LOOKUP ZONE in the DNSMgmt MMC for your DNS Server.   Right click on it and select create new zone.   The zone should be created to include the subnet of the server you are trying to add.  

You shouldn't need to  create PTR records for hosts that exist outside your subnets  (i.e. if you are adding an A record for convenience.... )

Thanks for the info. I'm confused about something though: According to the book I'm reading, Windows automatically creates an RLZ for the initial IP address you assign to an interface, but I don't see one under Reverse Lookup Zones in DNS Manager. The only zones listed below it are 0.in-addr.arpa, 127.in-addr.arpa, and 255.in-addr.arpa. Should an RLZ for my IP address (192.168.100.11) have been created automatically? It doesn't look like it happened in my case. Thanks.

(Correction: Actually, my IP addres is 192.168.0.11. I'm using the Microsoft Loopback Adapter for the virtual network, so my network is 192.168.0.x.)

I agree--they don't seem to be created automatically as far as I can tell. Thanks for all your help.
