DNS BPA Gives error "The Active Directory integrated DNS zone _msdcs.upp-ltd.local was not found."

Question

Friday, December 6, 2019 4:36 PM

Hi all,

I am looking into fixing an issue on our AD DNS servers - We have 3.

The error DNS BPA gives is: "The Active Directory integrated DNS zone _msdcs.upp-ltd.local was not found."

Below is a picture from one of our DNS servers. After reading a few sites

I am a bit unsure what needs doing. I do not have a DNS backup that we can restore.

Thanks in advance

Hi ,

According to your picture, the _msdcs.upp-ltd.local zone is a subzone under the domain.com. We need to create a separate zone. 

You could refer to Ace's steps in the following thread to create the _msdcs.upp-ltd.local zone.

1.Right click upp-ltd.local

2.New - Delegation

3.Type in _msdcs

4.Provide the IP of the DC itself. If you have more than one DC, specify more than one.

5.Under Forward Lookup Zones, create the _msdcs.upp-ltd.local zone

6.Set updates to Secure Only

7.Change replication scope to All DCs in the Forest

8.In a command prompt: run ipconfig /registerdns

9.Run net stop netlogon

10.Run net start netlogon

Error_DNS: Zone _msdcs. <DOMAIN> is an Active Directory integrated DNS Zone and must be available.

Hi ,

>>*Below is a picture from one of our DNS servers. *

What's your server OS version?

Looks like the image upload failed. Could you please upload again?

Was there a zone called _msdcs.upp-ltd.local on your DNS server? 

If not, as Ace said in this thread, the BPA is looking for a zone _msdcs.upp-ltd.local, but it does not exist.

Please created the zones and restart the netlogon service on all the domain controllers. 

Then all the necessary records should been registered that the zone _msdcs.upp-ltd.local. And then if you executed BPA again , it should not report the error.

Best Regards,

Candy

Hi Candy,

In the forward lookup zone i have _msdcs.upp-ltd.local but not entirely sure if this is correct.

Hi Candy,

So based on your image, i need to right click on the forward lookup zone and create this new zone?

I guess i should not delete the folder _MSDCS under upp-ltd.local zone?

Hi ,

If you are not able to create the _msdcs.upp-ltd.local zone, delete the _msdcs subfolder and then follow the above steps again.

If you could create a separate zone, then you could ignore the subfolder under upp-ltd.local zone.

You could first backup the zone in order to prevent some risk.
