I get this message trying to connect to my other pc on LAN. I'm using a DI-604 D-Link router and Road Runner is my provider. Please someone figure this out for me

Hi,

It's 192.168.0.100 the correct adress of the 2nd pc? if no change it by the correct one.
If 192.168.0.100 is correct you can ping 192.168.0.100? if no maybe your Subnet Mask is incorrect.
You can access to the ftp at 192.168.0.100 with a ftp client on it? if no check the port or if it's running.
can you access to 192.168.0.100 ftp with another ftp client? if yes, check that you have SmartFTP on your firewall allow list.
