By RDPing, I mean that I keep needing to RDP into the machines to navigate to AmazingCharts.xml every time someone complains that it's not working.
I tried to map the network drive, and I did check "Reconnect on Startup", but it still refuses to reconnect at startup and prompts for a password at boot. The main computer doesn't have a static IP, but the IP it's assigned via DHCP is fixed from the router.
