MSTSC security "log in to" drop down list

[ASE001]

I have windows machine that I RDP to from the internet using port forwarding and I want to beef up security. I’ve amended the registry to hide the users from the logon screen but I can’t seem to remove the domain/server names in the "log in to" drop down list on the login page. I would like to hide the option button too on this page!

I've tried setting ‘ShowLogOption’ to 0 in the registry but that only hides the list until the Option button is clicked. I've also deleted the Domain list in the registry but it gets recreated automatically.

I have a VPN server for general access but need a backdoor just in case my VPN server crashes or the kids switch it off.

Thanks for the feedback and will heed your advice. So I've decide to look at using a Raspberry Pi as a VPN server to provide a backdoor to my network (openVPN seems to have been ported to this platform). I can tuck one of these babies out of the way and it only consumes about 2watts. With my main VPN server that gives me two paths into my network.

I also have seen reports that the Raspberry Pi can be used as LDAP server and setup to provide SAMBA/Windows authentication?
