Domain on premises, Windows 2016 servers.

A domain 2016server ec2 instance, Amazon, AWS.  I can join the ec2 machine to the on premise domain over the VPN connection between AWS/on-prem... but when I try to promote as a domain controller it says "access denied".

Also, I found that if I open a windows explorer window on the aws ec2 machine, I cannot put \\domainname in the address bar and get the administrative shares but if I put \\ip-address I do get those shares.

I have tried putting the domain name in a hosts file on the ec2 instance, but no change.

Short version: can join an aws instance to an on-prem domain over the VPN, but can't promote the aws instance to a domain controller.

I could really use help with this.
