I have these two PCs, both joined in my home wireless network. I frequently access either of them using RDC from the other with no problem. But this time I had large video files to transfer and the wireless network was too slow. So I wired them and now they see each other from local area connection, and by that I mean, their shared folders are accessible in windows explorer and they both ping each other using either IP or computer name when one (or both) of them is disconnected from wireless network.
But RDC can not connect. It displays the common message:
Remote Desktop can’t connect to the remote computer for one of these reasons:
1) Remote access to the server is not enabled
2) The remote computer is turned off
3) The remote computer is not available on the network
Make sure the remote computer is turned on and connected to the network, and that remote access is enabled.
First I fixed their IP range, now they are 169.254.128.110 and 112, and both use 255.255.0.0 subnet mask. I tried both computer names and IP addresses. I also tried disabling wireless adapter on both of them, but no success.
This is something that I usually do when I want to connect to my laptop, I connect the laptop to one of these with the cable, then disable network adapter on the laptop, that it can be reachable just from cable and run RDC on the PC and done! But I don’t know what is wrong between PCs.
What else should I check to find the problem?
Edit: Short story
There are DT1, DT2 and LT in a home network. They all happily connect each other via RDC when they can reach each other through WLAN. Now, when I disconnect them from wireless network and wire two of them up at a time using same crossover wire, LT connects both DT1 and DT2 and vice versa. But DT1 and DT2 wont connect each other, however, they can ping each other. No firewall, no router, no gateway, same subnet mask, static IPs from same range but different from wireless network IP range. DT1 and DT2 are running win7 x86 and Lt is running win8.1 x64.
