Remote desktop credentials did not work

Question

Hi everybody...I've noticed quite a few problems with this around here, but my situation is far less complex. See I have a Surface Pro that I'm trying to use to remote access my desktop. My desktop is running Win Professional and has Norton 360 on it for
security. I'm just running over my home network at the moment so I'm operating within the same WLAN. When I try to connect via my Surface Pro, after putting in my desktops computer name, I come to the point where I have to enter the credentials. This was pretty
simple as I only have the one, So I put in my Admin log on info (just as I would to log on to my desktop normally). but after I do I get the dreaded "Your credentials didn't work" page. I've tried over and over again but It simply wont work. I have
both PCs set up to accept Remote access, I have Remote Display cleared thru the Firewall, I even tried at one point to use the non- NLA just to see if it would work, but to no avail. I can't connect from my desktop rig to my surface either. When I try that
I get "an authentication error has occured. The Local Security Authority could not be contacted", I saw in another forum that this could be due to an expired password, and even tho I assumed that was for a VPN access I ensured m,y passwords were
new and that I was no longer using a PIN to unlock my Surface. I'm kind of expelled my options here, I thought this would be a simple click-n-play  considering I'm in home and not using any other software/servers/whathaveyou but this setup has beaten
me. Can anyone help?

On your local machine Open Windows command prompt type: gpedit.msc -> Press Enter -> a new window will popout
Go to Local Computer Policy –> Computer Configuration –> Administrative Templates –> System –> Credentials Delegation
Double Click on “Allow Delegating Saved Credentials with NTLM-only Server Authentication”
By default it will be “not configured”
You will see radio buttons -> Enable the policy
Click the “Show” button in the options window below and enter the value “TERMSRV/*” (without quotes) into the list.
Click Apply button
Do the same thing for the following policies: 
Allow Delegating Saved Credentials 
Allow Delegating Default Credentials with NTLM-only Server Authentication 
Allow Delegating Default Credentials
Make sure that "Deny Delegating Saved Credentials" is not enabled or does not contain “TERMSRV/*” in the list
Close all windows
Open a command prompt and use “gpupdate /force” command to apply the policy directly.
I had an issue with Windows 8 RDP not allowing a login unless the computer name was typed in, and the solution above worked perfectly.  Thank you! Thank
