Hello:
Did a project some months ago for a customer. It is a Windows 10 application running on an industrial PC which is not connected to the Internet. This IPC is connected to two LANs, one on the PLC side and one connected to a laptop computer connected to an access point that lets me use TeamViewer to connect to the laptop, and then using RDP connection I can check my application. The access point device is inside the building and the signal is not too good, and in rainy days it seems to get even worse, refresh of screens become unbearably slow.
Recently the OS on the laptop had some patches installed and now I cannot see my application on the IPC. The RDP does get connected to the IPC but the screen is black, at least from here. Maybe from the control room it is visible. Going there is not easy due to the several hundred kilometers distance and COVID restrictions, as it is a candy factory, and also they do not have budget to get me there and I do not want to go there on our dime.
I tried several things, like changing resolution, enabling "turn-off UDP on client" in the group security policy. I also downloaded the new MS RDP from the MS app store but the behaviour is the same with the new one, I only see an orange screen.
Tried the FreeRDP client (which requires no installation), and this one gets connected to the IPC but only for about 5 seconds, then it crashes. There is an application called Royal TS which has a lite version. Tested it here and looks very good, but would need permission from the customer to install it, so before doing this wanted to know if anybody has endured something similar to what I described here.
One more thing, I had to do an additional change, which was to create an entry in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Terminal Server Client. I added the DisableClipboardRedirection (TRUE) because my application is an Excel macro that does a lot of copy+paste and sometimes the connection with the RDP would crash the macro. But after I did the change the RDP was working OK for a few days. So either the problem is some Windows patch, or the fact that the communication with the wireless access point is not good could be causing this problem? I ran out of ideas, thanks for reading.
