I think I have a little dns configuration error somewhere, but need your experience to help troubleshoot and correct it.
I'm working with a local network, actually a workgroup of windows 8.1 computers, all connected by a Dlink DIR-820L wireless router at 192.168.0.1 - the router has two wireless networks: one is regular and runs at 2.4 Ghz, while the second is faster and runs at 5 Ghz. I will refer to the faster wireless network as the media network.
I have set one of the computers to use a preferred address of 192.168.0.8 and its is connected to the media network, and on the router I can see it is connected and it uses the name Sphere.
From another computer, connected to the regular network, I have network discovery turned on, and I can see the computer sphere on the network.
However, if I use RDP to connect, and I refer to the computer target as sphere, it won't connect. If I use the ip address 192.168.0.8 then it does connect. If I use the name sphere in rdp, it asks for my password, but fails to connect, and just repeats asking for the password. But if I use the ip address, it accepts the password and creates the remote desktop normally.
I have tried deleting and recreating the rdp connection. Any ideas on how to fix this? Does it indicate some kind of dns problem?
