We have a hybrid environment, site to site VPN, and an Azure Domain. I've installed the necessary roles on the VM. I'm using the server admin wizard and when I get to the point of choosing credentials, it fails. The error I get using the account prefilled in the wizard, is: "Could not log onto the domain with the specified credentials. Supply a valid credential and try again."

    Hi @Eric Carr ,

    if I got you right your VM is Azure AD joined and you want to install this VM as an additional domain controller (DC) to the Azure AD?

    You can't promote a VM as an additional DC to the Azure AD. Azure AD is managed by Microsoft Azure and does not allow to add additional DCs.

    If you want to create your own AD domain you can do that. But you have to choose Add a new forest to install the first DC.


    (If the reply was helpful please don't forget to upvote and/or accept as answer, thank you)

    @Eric Carr Thank you for reaching out to us, As I understand you are trying to join/promote a Azure VM to a hybrid environment during the process you are getting error while entering the credentials.

    As part of initial troubleshooting, do check if you are able to reach/ping the domain name from the Azure VM, if yes try to join the VM to the domain and further you can promote it as a domain controller.

    But in the above query you mentioned Azure domain, which is not clear to me, is the domain verified in Azure AD and trying to join the vm to Azure AD domain.

    Let me know if you have any further questions, feel free to post back or you can reach out to me via email on azcommunity [at] microsoft [dot] com referencing this issue with a subject line "ATTN:Givary" and we can connect offline if required.
