DNS Wildcard – Fix Entry Not Resolving Correctly on Microsoft DNS Server

I am trying to set up a wildcard entry in MS DNS Server (on Windows Server 2008 within Active Directory) so that requests for all subdomains resolve to the same IP address. For example:

name1.my.subd.plop.com >>> 192.168.255.4

name2.my.subd.plop.com >>> 192.168.255.4

anythingyouwant.my.subd.plop.com >>> 192.168.255.4

I believe this should be simple but simply cant get it to work! I have tried two options, A records and CNAME records.

The A record in the plop.com domain is simply:

*.my.subd A 192.168.255.25

When I use nslookup to resolve a domain it doesn't report an error OR an IP address. Dig output:

C:\Users\myusername>dig anything.my.subd.plop.com

; <<>> DiG 9.10-P2 <<>> anything.my.subd.plop.com

From a client command prompt PING it simply fails:

C:\Users\myusername>ping anything.my.subd.plop.com
Ping request could not find host anything.my.subd.plop.com. Please check the name
and try again.

If I use a CNAME entry with an "*" nslookup reports the correct IP address but the client PING fails in the same way as above.

I am hoping this is a simple error that someone can help with, I dont mind looking silly if I can get it working, it is driving me nuts!!

More info:

I have created a new zone on my DNS server and added a similar wildcard entry. This works as expected.

I have changed my zone from a Primary Zone to an Active Directory – Integrated Primary which has had no impact on the response.

I added a wilcard A record (*) at the "root" level (i.e. *.plop.com) and this also fails in the same way.
