Windows Server 2012 – Can’t join computer to the domain

active-directorydomain-controllerwindows-server-2012

This was supposed to be an easy one but I ran into an issue here.

I set up the domain and a static IP on the server. The server is connected to a router/AP (which obviously functions as a switch) as well as the client, both are hardwired.

When I try to join the computer via This PC, I get prompted to enter the credentials and then I received the following error: "The following domain either does not exist or could not be contacted"

When I go to a different computer and try to log into the domain from the logon screen.

I receive the following error: "The security database on the server does not have a computer account for this workstation trust relationship".

I haven't been able to join a single computer to the domain, what am I missing here?

Don't ask me to rejoin the computer to the domain because I haven't been able to join anything at all

This is almost certainly a DNS issue. Make sure that your clients are configured to use a resolver that is able to resolve queries for your AD domain.
