Hi,

I was wondering if someone could help me on why or some how my DNS server doubled one day.

 

I currently have a windows server 2012r2

 

See picture

 

Usually the DNS on the photo was the ZEUS then of all of a sudden i see zeus,casa,local no idea how it got there but it seems like an exact replica

 

 

Thank you

I'd not be worried about it. You are not seeing two separate servers, you are seeing one console with two references to the same server.

 

Forgetting about DNS for a moment, the shell of the DNS manager program is just a normal Microsoft management console.

 

To that blank console DNS management snap in is added and that is pointed to your DNS server. It looks like a second DNS management snap in has been added, pointed to the same server. One referenced by just the hostname ("zeus") and one by the fully qualified name of the dns server "zeus.casa.local".

 

It would be easy to remove one of the references, but it's not doing any harm.

Actually the two entries appear to be someone making a child domain zeus.casa.local.

 

Expand Zeus.  Does it show zeus.local?

 

Can you expand both forward lookup zones so we can see what is listed in them?

Sorry, I beg to differ - The tree view on the left is showng DNS server names - the same server "zeus.casa.local" and (I presume) it's unqualified plain hostname "zeus". Notice that the top one is selected and that in the main pane the DNS manager information for that server is shown. That includes the "Forward Lookup Zones" node (in which I expect you will find a zone called "casa.local", which I think will contain a DC named "Zeus"...

Hi,

Thank you guys for the reply, Really apreciate

 

Well Here im attaching 2 photos one that is my server and another i put up a while back it seems that zeus is the dns So not really sure if i should do anything about it? but it does somewhat seem weird all of sudden out of nowhere. Well actually not sure it this has to do anything but Been trying to implement WPAD and i did have to delete GlobalQueryBlockList the string WPAD for it to resolve.

You do not need to do anything - your network will not suffer in the slightest by having the two references in that console.

 

It wouldnt be an intended effect of the WPAD thing. It could be something that you did whilst investigating the issue, but it realy is trivial. I'd leave the second reference alone.

Thanks Really appreciate the info :) So if i wanted to add another A record I would just add it on the Zeus section? and should replicate to the zeus.casa.local?

There is no replication to be done. Changes you make under Zeus will appear under 'zeus.casa.local', not because it needed to replicate to get there, but because it is is the same place referred to by two different names.

 

I think that zeus is the name of your domain conttoller/DNS server, and that your domain is casa.local

 

 

Whist on your network, you can refer to that server by just ist hostname 'zeus', or by its fully qualified domain name 'zeus.casa.local' - it is the same server.

X64 is right, its 2 connections to the same server, one being just zues (Netbios name) and then other has been the FQDM.

open the mmc and connect using netbios name and then connect using the FQDM

 

Personally i always make a connection to netbios name.
