I have two workstations running Windows 8 on my network that I am unable to RDP into. I can RDP into every other PC on my network without any issues and all of the settings are distributed via group policies, so they're identical on all of my workstations. I have tried connecting via the workstation's name and IP address. I also cannot ping the workstations.
I have made sure the computers are set to allow remote desktop connections, they are listed within Active Directory and my DNS server, Windows Firewall is disabled, and I am using Trend Micro Worry-Free Business Security, but it is active on all of my workstations and it shouldn't be restricting remote desktop connections.
