Forest DNS Zone Master role, right DC?

Hi, I have a forest with one root domain and three child domains. The "DC=ForestDNSZones,DC=domain,DC=local" fSMORoleOwner is pointing to a DC (valid and working) from one of the child domain...

Yes, I'd expect a root domain controller to be the FSMORoleOwner in root domain. Another option is to start a case here with product support.

Sounds right. The PDC emulator for the domain is generally the fSMORoleOwner.

Hi Dave Patrick,

Thank you for your quick answer. Maybe it wasn't clear in my question.

I have a root domain domain.local
I have a child domain child.domain.local

domain.local FSMO:
DC1.domain.local - Schema, Domain Naming, PDC and RID
DC2.domain.local - Infrastructure
DC2.domain.local - DC=DomainDNSZones,DC=doamin,DC=local
DCb.child.domain.local - DC=ForestDNSZones,DC=domain,DC=local

child.domain.local FSMO:
DC1.domain.local - Schema, Domain Naming
DCa.child.domain.local - PDC, RID, Infrastructure
DCa.child.domain.local - DC=DomainDNSZones,DC=doamin,DC=local
DCb.child.domain.local - DC=ForestDNSZones,DC=domain,DC=local

My question is: the fSMORoleOwner for ForestDNSZones is correct? Shouldn't be DC2.domain.local (Infrastructure master of root domain)?

Regards,
Luis

  Normally would be the PDCe for domain, but would probably have defaulted to the first domain controller installed.

    Dave Patrick I understand that, but in that case shouldn't be one of the root domain DCs? Why is it a child domain (obviously created after) DC with no other FSMO roles assigned?
    Should I leave it as it is or change it to a root domain DC?
    
    Thank you.
