Is it normal for the Enterprise Domain Controllers group be hidden?
I can’t see it in ADUC but can in ADSI.
All this because I was reviewing AD groups and I am in doubt if I follow this guide or this one.
In my group I have these:

• Read-only Domain Controllers

• Domain Controllers

• krbtgt

• Domain Admins

• Enterprise Admins

• Schema Admins

• Cert Publishers

• Group Policy Creator Owners

Current Domain Functional Level is Windows Server 2016.

Thank you very much for your time and advice.
