I try to connect to a Windows Server 2008; I can get to the login screen but any login attempt fails.
I tried local and domain users, admin/not admin…
Using 'PsExec', I am able to open a remote command line. I created a new user (in case I was wrong about every single credential I tried ), and added it to local administrators.
Still can't connect. (wrong username or password)
It has been rebooted.
I even disabled the firewall.
What could prevent me from login successfully ?

Make sure the system's time is within 5 minutes of your domain controller for domain logins. Another trick I use is to type the password in the username field to ensure there are no stuck keys or other oddities occurring with the keyboard input.
Check that the users in question are allowed connection via remote desktop. You should be able to check this with the computer management mmc console (should work if psexec is working). Check the local security policy to ensure it is allowing the appropriate users console and remote login permissions.
