Running Wireshark on our network, I see one of the machines trying to resolve the name “ISATAP” by NBNS. That’s not a machine on our network and has never been, as far as I know. I’ve tried searching for all the .lnk files on that machine and checking their properties, and nothing is referring to “ISATAP”. Also checked the registry, no reference to “ISATAP”. Does anyone know another way to find out where that query is coming from? Thanks.
