Remote Desktop only working on Primary ACN

I have v15 installed on my Proplus, which is part of a domain. (redundant IDCC on A/B network). I am not able to remote desktop to the Proplus on the Plant LAN. I have my laptop and the Plant LAN NIC on a switch. I can ping the IP address. I also get to the point where it asks for credentials. However, when I enter either my local account (Emerson or Administrator) or my domain admin credentials, it says credentials did not work. 

My IT guy spent a couple hours and thought the office domain was causing problems, and he got it to work when unplugging the LAN and trying a RDP session on the DV Primary network from the IDDC. However, as i stated, i tried this with an almost direct insulated connection (via the standalone switch). So I've eliminated all outside traffic. 

So, then I tried from my laptop hooked up to the Primary ACN switch and I was able to start a session no problem.  I then went to the IDDC he tried earlier and tried connecting over the Secondary ACN. This did not work. 

So, from either my laptop or the IDDC the only network i was able to establish a RDP session on was over Primary ACN. Not sure what accounts I all tried, but I know for sure I could login with the Emerson credentials.

I stumped IT network admin... so I'm hoping this is something unique to DV.

Thanks, as always.

  • I should add that VNC has shown to only work over primary ACN as well. I also can not ping any of the networks unless my NIC is set to the same subnet. This goes for VNC as well. Seems strange. And to be clear i have all of these networks setup as switches on my desk. There's nothing else on the network, no firewalls, routers or anything. Just the 3 switches. Proplus, 2 IDDCs and my laptop
  • PlantLAN RDP should work. Is the switch managed or not managed? Can you open PowerShell or Command Prompt as an administrator on the ProPLUS and give us the output of the following? ipconfig /all

    Do the same for your laptop. Note that if you are trying to login to the domain from a computer that is not part of the domain, your username must contain the domain name in it <domain/username>. The window should also show the domain you are trying to login to.

    I should've noted that you should mask out any information that could be used to identify your system. Operational security is more important than troubleshooting these kinds of issues.

    idk how.... but someway or another i ended up with B and C networks swapped...... ugg. At least give me props for admitting that on an open forum. Lol. Problem resolved.
