Hi,

Installed server and client to each laptop.
However client discovers but can not connect to server.
Server makes a sound then another sound and client says "could not connect to ....:5950"
I also do not see another screen added as a virtual screen in server laptop.
What might be happening?

Here is helper.log

Connected to service pipe \\.\pipe\UVNCExtDisp.1.3801718
