Grey delegation in dns

Hi experts,

I just add a new child domain to my parente domain.

But I have some dns issues.

In parent domain my child domain delegation appears grey in dns zone. (see greydns.jpg)

If I delete the child domain delegation and delegate again, I get this erros (see name-server-record01 and name-server-record02)

The parent domain and child domain are connected trought a vpn.

I use windows server 2008 R2 in both servers

Best regards

Ok, situation point.

If I ping dc01 from child, he resolve to dc01.florasul.lan (parent), sounds good

If I ping chld01 from parente I get this

But not resolve to CHLD01.evora01.florasul.lan, it is a problem?
