Unknown PC on my Secured Network

Download the the free LanScan from the MacApp Store. There is an

optional subscription for advanced features which you won't need

so don't worry about.

It will scan your network (enter the desired IP range) and will give a pretty

detailed list. For one, in terms of MAC Addresses, it can generally determine

the manufacturer and you may further be able to ID the device (Manufacturers

can buy "blocks" of MAC addresses). If the device has a hostname, mDNS name,

or SMB name it will display those as well.

And that's why it shows up as a PC?

The presence of an SMB (Windows) file share service is what that icon means.

That’s one of the ways that macOS uses to detect a Windows or other system present on the local network.

And yes, if you look very carefully, it’s a BSOD.

As for what that file share is doing, check the manual.

It’s probably used for where scans are located for later retrieval.

Your printer has a file share.

A Windows Phone or a Microsoft Surface might appear as such.

if you are using a password that has any dictionary words on your WiFi, you should change it.

Vowels are easy to guess. Mix letters, numbers, and and funny characters and cases. 16 characters now is best

for security. 8 characters can be characters you remember, 8 can be characters that are different you write somewhere physically secure (not a computer online!)

Apple's Bonjour service has detected a device on your network. It might be a network attached storage device, an iPad, a networked TV, a Roku, or Sling box, an XBox, or just about anything else connected to your network, either wirelessly, or wired.

In my case, two of my NAS and the venerable Western Digital WDTV Live box show up.

What kind of PC is that, showing in >Finder >Network? I don't have/own a PC and never connected one to my network. When I click on Get Info, there is not much information to it (see photo below).

When I go to >Utilities >AirPort Utility and click on my Time Capsule, I see all my devices that are connected to my network (e.g. my MBP, iPad, iPhone, WiFi-speakers, etc.) and a device that's called 2B79E5000000.local (the same device that's showing in >Finder >Network).

Under >System Preferences >Sharing my computer's name is Airwalker-MBP.local

What and who is 2B79E5000000.local? By the way, I am NOT using a virtual PC on my Mac.

Log into your router as admin: http://192.168.1.1/

and look at "All Connected Devices" for common names:

...And if you still dont recognize it block it on the router and see what stops working

One clue is the hexadecimal address of the machine. Generally that matches the Media Access Control address of the device. This is usually labelled on the outside of the device as a "MAC Address." (no relationship to Apple Mac, or Macintosh).

It is a unique address for every networkable device using letters and numbers 0 through 9 and A through F.

Great help, thanks! I have downloaded LanScan and see my MBP, my two iPads, my iPhone, my Canon Printer my 7 Sonos speakers, my Samsung TV and even my Garmin Scale (when it's on) on the list. Great app!....

I used it quite a bit when I was working on embedded processors with

a network interfaces. It was the only way to know if they were on the network

and narrow down communication issues.

It is probably because the printer has FAT32 or NTFS based storage, which is PC based.

it’s usually an SMB server on a network-attached server file share or a file share on a printer, on some (transient?) Wi-Fi device, or other similar device with a file share, when these questions arise.

As for poking around on the Bonjour network, I’ve been using Bonjeff—this is replacement for the older Bonjour Browser.
