Old thread, I know. We recently switched to having all our computers running Windows 10, and immediately noticed that networked computers with shared directories would sometimes show up in the Windows Networked devices area, sometimes not. I tried setting static IPs for all computers, first by individual machine (and that was a pain when trying to connect to other wifi routers), and then via the router settings, which supposedly still permits DHCP assignment on other routers (presumably with different gateway addresses, but who knows?). In any case, I found that unless we used DHCP with dynamic LAN addresses on our office router, Amazing Charts was not reliable, and would often fail to find the main computer. Is this a known issue? We're using AC version 8.3 (but that's another story). Thanks, Kurt
