Windows 7: Remove Unknown User From Network

> in this case i assumed Tom was a domain because of the, connect TO Tom's domain.... security prompt screenshot.

The only place that I see the word Domain in info coming from boweasel is in the screenshot attached to the first post. In that screenshot, the prompt mentions Domain: SCOTT-HP, not Domain: TOM. In that same screenshot, TOM is listed as a device on the network. The MAC address for the device named TOM seems to indicate that TOM is a computer made by DELL.

When the user on the computer named SCOTT-HP clicks on the device named TOM in the Network section within Windows Explorer - authentication is automatically attempted. That authentication uses the credentials of the user that is currently logged on to the computer named SCOTT-HP or other credentials that the current user has stored. (There are more credential options - but let's leave it at that.)

If the automatic authentication fails, then the user of the computer named SCOTT-HP is asked to manually provide credentials for the authentication process. That is the prompt that you see in the first screenshot in this thread. If the user of the computer named SCOTT-HP cannot provide the correct credentials, then that user cannot access shared folders and printers (if any) on device named TOM.


The computer named SCOTT-HP is its own domain. In other words, it stores user credentials. The security prompt shown in that first screenshot is letting the user know where the operating system is going to look to verify the credentials being manually supplied for authentication to the device named TOM.

I am such an EFFING IDIOT!!!!

I cannot believe how unthinking I was, and I sincerely apologize to everybody's whose time I've stupidly wasted...

A couple of months ago a neighbor who I'm not particularly close to, asked me to see if I could get anything off of his ancient XP desktop. I plugged an Ethernet cord into an empty port on my modem/router and with some difficulty was able to copy his pictures, music and documents to a USB drive. I gave him the drive, he told me he didn't want the old XP, and that's where I left it - still plugged into my modem/router. I guess it goes without saying that this neighbor/acquaintance is named Tom.

When I went downstairs last night to cycle the modem and router I saw this unknown computer hooked into the unit. It took only a few seconds to realize what had happened. Apparently anything I plug into my modem/router shows up as additional network in Windows Explorer, something I either forgot or didn't know.

Along with my apologies I'm going to add to everybody's reputation. You all deserve so much more.

BTW, when I disconnected Tom's old desktop from my modem/router the network TOM disappeared from the Network heading on the left side of Windows Explorer. When I then plugged another old XP desktop into the same port here's what I got. I have no idea why one computer caused the individual's name to display while the other brought up the make and model.

boweasel,
It was fun and I learned stuff. Glad that it was nothing bad.


GokAy,
Do you agree that Microsoft is calling a Windows 7 Home Basic computer or a Windows 7 Home Premium computer its own domain? I am basing that on the first screenshot in this thread and my testing on a Windows 7 Home Basic VM.

The computer that Tom used was named TOM.

Device names show in that Network section, not users.

And devices can be set to not show in that list :-)

Boweasel: You can change the names of your computers by right clicking Computer (Desktop icon or in Start Menu) and selecting Properties.

UNI: Yes, matter of speaking, all standalone PCs are in a "domain" of their own. They are fully authoritative within their boundaries. It is the standard dialog where it says DOMAIN: PCNAME when no domain is found. I don't know why they worded like this, maybe too lazy to put an if statement there in the code?

Thanks GokAy. I had never thought much about that term as it applies to a Windows 7 Home xxxx install until this thread. Most of the computers that I work with are XP Pro or W7 Pro. I created a W7 Home Basic VM just for this thread so that I could see that Domain: PCname in the credentials prompt.

So, if each Windows computer is its own domain...
...then technically - one can ping a domain :-)
(I knew what you were saying.)


boweasel,
Don't mind us. We are just rambling on in a solved thread :-)

In XP there were a 3rd box for domains (as far as I remember - although domain\user or user@domain would work too. You could select a domain or local computer) while logging on. Can't remember if it was there in network too or just welcome screen though.
