Description
I've been trying to do this off and on for several years and on many versions of VB without success. I've been through the documentation many times and asked for help on the forums. Nobody has been able to find a solution and others have reported that this happens for them as well, including on Mac OS and Windows 7 and 10 hosts.
Host OS = Win 8.1
Guest OS = Win XP
VB version = 6.1.8, with matching extension pack
VRDP Authentication = External/default (VBoxAuth)
VRDP Port = 5003
This process works fine if Authentication = Null, but when set to External I cannot make a connection from my local host (or any other Windows host) to the guest machine via VRDP. MSTSC tells me "This computer can't connect to the remote computer" before it even asks for a login.
I have been trying this on many different versions of VB, going back to the early days of v4.x. Considering how widespread it seems to be in VB releases and across various hosts, I would think this is a problem that is part of the basic functionality.
A log is attached, but the important message from it seems to be
"AUTH: external authentication module returned 'access denied'"
