You can't wildcard a CNAME, it must be an A record.

That is, you can do this:

*.widgetstest.widget.com.   Host (A)   1.2.3.4

And "anything.widgetstest.widget.com" will resolve to 1.2.3.4. But you can't use a CNAME with the wildcard it won't process it.

Try to connect to ForestDNSZones or DomainDNSZones using ADSI Editor (depends on DNS zone replication scope) and try to remove that orphaned DNS zone.

How to connect to thi naming contexts:

Look for
For Option 1: [ForestDNSZones]
For Option 2: [DomainDNSZones]
in this MS article at
http://support.microsoft.com/kb/867464

Before you will do that, do your DC's System State Backup and be careful

The delegation will exist as a greyed-out folder in MS DNS within an existing zone.

It's less likely to be an orphaned object in AD, that wouldn't present as a broken delegation.

I had that folder and I deleted it.

I should say I had that folder before I posted this and already have deleted it.

When I loaded the forestdnszones in adsiedit I do see an entry DC=..in progress + a string of numbers and then the dns zone.

It's likely to be a tombstoned entry, dcdiag shouldn't be able to find that.

I removed the new domain folder I had created under my primary ad integrated dns zone and not dcdiag runs fine but shouldn't I be able to create a new domain under my primary dns domain and then add records to it.  when I tried I got  a message stating that this server is not authoritative for the domain.

Hmm exactly what are you adding in relation to the current zone? Just "New Domain" (to create a delegation)?

Did you create the child zone separately first?

One more question, 2008 or 2008 R2? The DNS console has made itself progressively "helpful" between versions, in some cases to the extent that it's counter productive.

2008 R2.  You are going to be sorry you asked what am I trying to do.

I have my main domain say widgets.com.  I have the need to create a dns namespace called widgetstest.widgetscom.  This is just a dns namespace/zone not an actual windows domain.  In that zone I need a wildcard record *.widgetstest.widgets.com.  the machine that the wildard entry will point to is actually in a windows child domain of widgets.com.

So far I have not been able to get this to work.  I have tried many ways.

Okay, that sounds fine.

You don't have to create that as a separate zone, but you can if you wish.

If you want it within the zone, you'd simply create a Host (A) record with this name:

*.widgetstest

The grey box should make that into *.widgetstest.widgets.com.

If you want it to be a zone, create a new zone called widgetstest.widget.com, then add a Host (A) record for * and the appropriate IP. You may find that step creates the delegation for you, you'd only need alter that if you have more name servers for the new zone.

I created as you stated but the name does not resolve, cannot ping and nslookup from the DC/DNS server gives non-existent domain.

Also I added a primary no AD integrated zone.  Added a cname wildcard record and also another cname record.  The wildcard does not work the other cname does.  This is from the DC/DNS server.

dmwynneAuthor Commented:
OK I added it as an A record and still cannot ping it.

On a side note in my sub-domain I do have a wildcard setup as a cname and it works.

Can you screen-shot your new zone at all?

I can't post online but could email it to you.

Chris DentPowerShell DeveloperCommented:
It's not ideal, but I can't see it being much more than a tiny little error, DNS just isn't that deep most of the time.

My e-mail address is in my profile (in a slightly abstract format), if I find anything in it I'll be sure to document everything here with obscured names.

OK, I managed to get what I needed working to work.  I will post details later.  Thanks for help.

And I'd forgotten I was supposed to reply. I'd be keen to hear what it was since the screenshot you set had everything looking right.

I ended up creating a delagation from the parent domain to the child domain.  I then created a primary non active directory integrated zone in the child domain.  On the parent domain contrller/dns server you can see the greyed folder for the zone that was delagated.

I added an A record for the host I wanted the wildcard to point to but I left the host blank.  I added another A record for *.childdomain.domain and pointed that to the same host.

Not sure why that worked.
