Windows 7: Remove Unknown User From Network

Remove Unknown User From Network

I just noticed that when I use Windows Explorer, there is an unfamiliar name on my network. When I click on that name I'm presented with a Windows Security screen prompting me for a User Name and Password.

I have no idea what that screen wants, who the user is, or how to remove it.

Anybody have ideas?

Hi Scott,
As you dont recognise the user dowload and run Malwarebytes free, uncheck 30 day trial.
Then in the settings option tick scan for rootkits.

If you Right click on Tom, it should give you the option to delete it.
If not Rght click on your signal bars select Network/sharing then on next screen manage my networks,
right click on Tom and the dropdown will give you the remove option

Already run Malwarebytes and scan for rootkits was checked. Right-clicking on Tom only gives the options to Expand (which brings up the Enter Network Password box again), Connect with Remote Desktop Connection (see below) or Open in New Window (ENP box again). No delete option.

Clicking on Manage Wireless Networks from the Network and Sharing Center fails to display any network called Tom. But then again it doesn't show EMACHINES-7AF6B9, Scott-HP or Karen-PC either. Those computers are all part of my Homegroup.

What do you get when you expand Homegroup Karen.

I see the 2 folders that are part of the Homegroup on the Karen-PC. The Emachines computer is a desktop that is directly connected to my router. I set up the Homegroup on the Karen-PC and added the Scott-HP to it. The Emachines desktop was never added to the Homegroup. When I click on the Emachines I get the exact same message box that I do when clicking Tom.

You might learn more about the device from your router's interface.

If you can find a MAC address for the device named TOM, then you might be able to tie it to a particular vendor via this list:

It takes a while to render that page.

If you have an unprotected wireless connection set at your router a neighbor may have "accidentally" connected to it.
Try in cmd:
ping tom

You would also see other PCs in your network if you have network-enabled virtual machines running on one of your PCs.

Yes, I can ping Tom. However I have only the one wireless network using WPA2-PSK security. I'm running 2 laptops, 1 tablet and 1 desktop off that connection. I also have an old non-wireless HP printer that I set up as a network printer so we could use it on any of our laptops without having to be directly connected.

Frankly I don't know what that means. Sorry.

This is a combination modem/router from my ISP. Accessing it gives me this page about MAC filtering
