So I just got a new desktop, a Windows 8.1. Set it up to use my Microsoft Account credentials just like my old Win 8.1 Pro machine did. Once I got it setup and going I tried to remote desktop into my Windows 8.1 Pro using my MS credentials and it worked fine, once. After that I got the "credentials did not work message" and it wouldn't connect. I checked permissions and everything on the Pro machine, even turned off firewalls on both machines but it still wouldn't connect.
Finally, I created a local account on the Pro machine and voila it connected (using localaccount/user. A strange issue, but even stranger after I tried connecting from my iMac using MS Remote desktop connection for Mac. It connected using my MS Account credentials!
I've looked at some of the remote desktop connection issue threads and none of the solutions suggested seem to work for my issue.
Does anyone have a suggestion as to what I need to do to fix this?
