Always show local users on a computer connected to a domain

I have a Windows server 2008 domain with a connected pc. I want my local user to always be shown on the logon screen. It had also be nice to only show the username and not localcomputername\localusername. I understand that this settings are located somewhere in the register.

Thanks for all help.

Just have a look in the below link. It gives settings about preventing the last logged-on user name from being displayed in Windows server. You just need to check that and disable it. The settings are easy to verify. Just follow the steps below and just disable Do not display last user name in logon screen. Once you did reboot and check back.
Prevent the Last Logged-On User Name from Being Displayed
