Problem in using RealVNC in local wireless network

[deep1234]

Hi guys, I want to control a computer in my local wireless network using RealVNC. I installed VNC Viewer in my computer and VNC server in the remote compter.

For the remote computer I set the password and open the port for it in the firewall (port 5900 TCP), but when ever I try to connect to it from my PC it give me 'Connection closed unexpectedly'. I checked the FAQs of RealVNC and it refairs that the problem is related to firewall?!, but I opened the firewall in the remote PC? and I even open it in my PC but it is the same thing?

So guys what I can do more? I am not sure if this is right but do I need to open ports in the wireless ADSL? but I want this in the local network not accross the internet.

Please help and thank you in advance.

Note: forget to mention before that this happened, when I try to connect it give me a "connection aborted (10053)". but the weird thing that it can connect after I try to ping it from powershell, but it give me "Connection closed unexpectedly" later.

disable the firewall on the computer you want to connect to. completely and uterally disable it, remove it if you have to. damn pieces of crap always causing issues like this, no need for them anyway if you have a router between you and the internet.
