Test, test and re-test, especially to see if name resolution is still failing or not when the incriminated laptop is off line. If your DHCP srv is updating your DNS srv, check it is still the case; if your DNS srv isn't basically updated by the DHCP srv, then you have a DNS problem. Other useful thing: either with and with out the criminal online, use 'arp' (pkg net-tools on Debian) as root to get a list of all resolved (or not!) IP addresses and MAC of your network. Oops, forgot the main issue: check laptop isn't behind a router, as they usually do not allow broadcast packets to pass through. > > The one unusual thing I can think of is that over the summer this > laptop had a boot drive fail, so I had to wipe it and reinstall Win10. > Maybe somehow that resulted in “two machines” sharing the same MAC > address?
