I have a number of PCs at home that I want to keep running 24x7 and some don't have monitors attached. When I need to access the desktop of those, I typically just connect them to a TV in that room however it's a pain in the butt.
Ideally what I would like is to be able to remotely access and control their desktops from my main computer without having that computer to need to grant access each time, which would defeat the purpose (I think teamviewer required the remote computer to grant access each time from my experience with it a long time ago - but this is possibly just a setting?). I do want & expect to type in a login/password, but just don't want the remote computer to need to grant access each time.
All PCs are on the LAN (5 PCs in total).
They all have access to the internet so I will need to be able to restrict remote access to LAN only. Even better if they can occasionally be accessed over the internet from a laptop, but secure it down somehow to only my laptop (handy for when I go on holidays).
They all run Windows 10.
I don't mind paying for software if need be.
Any thoughts or recommendations?
any VNC software will work, there are a few different versions out there. Or if you prefer you can just use the built-in remote desktop software. Just google RDP.
