[QUOTE="MacInWin, post: 1941480, member: 396914"] OK, here is the whole network. I have an ISP modem in bridge mode. I have an Eero mesh network with the main router that provides DHCP service connected to the ISP modem by Ethernet cable. There are four Eero units, plus two Eero extenders, in the mesh net. None of them are named Kitchen. I have two Minis, one MBA and one MBP, all running Sonoma, latest release as of yesterday. All four Macs (two Minis, one MBA and one MBP) are attached the local network both by WiFI and Ethernet, and all four show two attachments in the Eero list of devices. The Mini with the issue is named "KItchen" and the other is named "Theater". Both have external drives I use as network storage, so they both have File Sharing turned on. But only the Kitchen has the name issue. Theater has no such issue. I have 5 AppleTV units, all at the latest version of tvOS, none named Kitchen. I have 8 cameras attached by Wifi to the network, none named Kitchen. Five are internal, three are external, all connected by WiFi. I have 30 Homekit devices, mostly switches for on/off, but one camera. None named Kitchen, although one room in Homekit is named Kitchen, but it's been that way for almost ten years and it has multiple devices in it, so I don't think that is related. In the list of devices in the Eero interface the Homekit devices just show up as manufacturer names, not the internal names given to them. I have one Epson printer and one HP printer, each shows up by their own manufacturer network name, none are "Kitchen." To be clear, in the Eero router list of attached devices there are two connections named "Kitchen," one for WiFi and one for Ethernet, and neither of them shows the "(4)" being added by macOS. There are also two iPhones and two iPads attached by Wifi, none named "Kitchen." So my puzzlement comes from the following: 1. How does macOS come to think that there is a device already in the network with the name "Kitchen (3)" so it has to move to "Kitchen (4)" when no such device is in the network at the time? Is there some internal table (localhosts, config, hostnames?) where it remembers what it thinks it has seen as opposed to actually checking in the network? I've looked for any hosts files and only found generic localhosts files. Could it be some configuration or plist for SMB? I've been banging my head on this for days because it simply makes zero sense for one computer to act one way and three identically configured ones to act differently. Something HAS to be different about the Mini, but I cannot find it. [/QUOTE]
