RDP not working on one machine at home

Hi guys,
I have several machines at home that have RDP enabled. All are running Windows 10 Pro.
I have enabled RDP on all via System Settings > Remote.


I have also gone to Computer Management and setup the same users in the RDP Group.
Here are the machines that I have
DT1
LT1
LT2
LT3

I can connect to and from using RDP to any machine but 1. DT1.
It will let RDP to find it. I can access it's share drives no problem but RDP will not go to it. I can however RDP from it to any machine.

I keep checking all the settings, I've allowed RDP via Windows Firewall. I have Norton installed which I disabled but still no luck. All machines have Norton installed and I did not touch Firewall on those at all but they were fine.

Anything else I can do guys? Please help.

update:
looks like it was something with norton that was blocking the port for RDP. i had confirmed it was enabled but seems like a glitch or something.
uninstalled and tested, rdp works
installed norton fresh and works :)
