Which VNC server/client should I choose?

Question

System administration

There was a need for remote control of computers (different versions of Windows) in the local network. What are the options besides RDP? Which VNC server/client should I look at first?
Of the mandatory requirements, free for commercial use.
Upd: about 50 computers

Answer 1

I also struggled with this issue. Of all the revised ones, I chose TightVNC.

Answer 2

And why didn't RDP fit? Need something to show the user? Then you can use the regular remote assistant.

Answer 3

Up to 10 computers can use RMS

Answer 4

alas ... but a large number of computers + convenience does not fall under the concept of free. everyone knows it. and that's ok
