|The name resolution for the internal computers did not work.|
If all computers get an ip address via DHCP from the router, it should be possible to access the computers by name.
When using ip address to access the computers, you have to make sure, that you*re also use the correct port.
By default, VNC uses port 5900.
In the case, that you haven't change it at the kids computers, you don't need to set the port to access them.
E.g.: (for default port)
Let's say kids computer 1 has the ip address 192.168.1.100
So in the VNC client, you have to type:
But let's say kids computer 2 has 192.168.1.101 and VNC is configured to listen to port 6900.
In that case you have to type this:
So you can see, you have to check the settings for the ip addresses, whether they get the the ip dynamically via DHCP, and you have to check the VNC server settings at the kids computers to figure out the used port.
Also check, whether there is running a firewall that may block VNC.
