You did all that to get the RA to work too
Seem-2-me that Vail still needs the WHS team to fix this before it hits RC.
Hopefully before the next public build, if there is one.
I was trying everything, not sure exactly what finally made it work, maybe all of the above.
I thought maybe it was that I had created the new user, but then I had already did the port forwarding thing, which made the computer backup work, but not the remote access, that is when I created the new user. I sorta stumbled onto that I needed a new user, when I tried signing in Remotely using Administrator and the password, and got this message; "To protect the security of your home network, you cannot sign in remotely by using the Administrator user account. To manage your home network remotely, sign in with your own user account. Then in Computers, click Connect next to your server name to connect to the Windows Home Server Dashboard."
And I realized, that Duh I had not created a new user, I had attached or connected computers, but not created a New User, so I don't know exactly what was the final straw that got it working.
