Our company has a few Google Cloud VMs running windows server, our on prem machines connect to these VMs over a VPN. We don´t have physical servers, everything is in the cloud.

We are working to implement Active Directory. Currently, all our machines are standard to each employee (not joined to any AD domain), and thus we have very little control over them, we can not assing group policies and so on. We would like more control over these machines.

So far we have taken one of the VMs and raised it to domain controller. We have installed the nessesary server roles such as DNS and remote desktop services.

The problem here raises when we try to join one of our on prem machines to the domain.

When we hit the option in the client to join the domain and type the domain name, the credentials dialog window appears, we put in the name and password for the user hit enter, after a while an error occurs and it fails to join the domain.

I can’t replicate the error at the moment but as soon as I can I will update it here.

Is there any tool in AD to see if the client is reaching the domain controller, if it is seeing the request, and so i can see the error it produces server-side?
