So I've remotely created my first headless using ssh. Now I'm attempting to connect to this VM using RDP so I can install Ubuntu Server, but I cannot get connected at all.

When starting the VM everything appears fine:

$ vboxheadless -s WebTesting
Oracle VM VirtualBox Headless Interface 4.0.16
(C) 2008-2012 Oracle Corporation
All rights reserved.

VRDE server is listening on port 4455.

And showvminfo shows:

VRDE: enabled (Address, Ports 4455, MultiConn: off, ReuseSingleConn: off, Authentication type: null)

However I'm still prompted with the "enter your credentials" screen every time I attempt to connect. From reading the documentation null shouldn't prompt me with this screen at all...

Any help with this is greatly appreciated.

P.S. I am using ssh tunneling in putty to tunnel in to my network.

Are you positive that the authentication error is coming from virtualbox, and not from something along your tunnel? – Andrew M. Apr 7 '12 at 0:23
Not sure, I assume no I haven't set up anything else that would require authentication. I'll have to try it when I return home next week. – b1ackjosh Apr 19 '12 at 19:11
