Newbie Network Name Prob

I just bought a new Windows 8 PC, physically plugged into my hub, brought up a browser with the hub's setup screen and a different name appeared as the Device name than I had given the PC.
I ran nbtstat -A on its IP address and it comes back with two (well four with workgroup entries) entries MyName + funnyLooksLikeFactorySetName, how does the PC have two entities (of course only one network card).

The network connection on my Windows 8 machine works the same way as on my Windows 7 machines.

Is IPv6 turned on as well as IPv4? And are you getting two Device names because of that? That seems most likely.

On the Windows 8 machine, what does IPCONFIG /ALL say?  Perhaps post the results.

Also, is the wireless connecting to something automatically?  It shouldn't; it should ask first.

So first, is anything wrong?

Second, you have set up tunnel adapters (either disconnected or with IPv6 addressing). I don't think Windows 8 sets these up automatically. I do not have these on my Windows 8 machine.

Then, finally, your main Ethernet is 192.168.1.67 and that looks all normal.

So I think what you are seeing is the tunnel adapters. If it is all working, there may not be anything to worry about.

Ok, my issue is, which may be another thread...i'm trying to setup Windows Remote Desktop to the machine, so I thought I wanted to type ipaddress/computername, but i'm not sure i'm getting the right name...? It doesn't seem to be getting there anyway.

First, correction to my post. I do have the tunnel adapters but they are all down at the bottom. They do not interfere.

Second, there is no reason why you should not be able to get into the machine using IP address. You should be using 192.168.1.67.  Make sure Computer, Advanced Properties, Remote connection is set up to allow access. Make sure your Firewall allows the subnet you are working with.

The name you want is also in Computer, Advanced Properties. There is only one Computer Name. There cannot be two.

Make sure that the computers you are using are all in WORKGROUP.

Sorry I didn't mention - i'm trying to access remotely from outside the hub firewall (which is www static IP), which for me throws up two questions regarding your previous post:
That IP address (192.168.1.7) is dynamically assigned, I'm not sure it'll be there.
If i'm outside the hub the workgourp doesn'#t have any meaning does it?
I have opened up the port on the firewall for remote desktop, but I'm not sure if its forwarding to the right PC.

If you are trying to access from outside without a proper VPN connection you are leaving your computer wide open to the internet. Bad idea.

WORKGROUP should not interfere if outside but I keep mine all the same at WORKGROUP to eliminate problems.

What I would do is connect to the Windows 8 machine from INSIDE your network. Prove that all is working and check what addresses are being used. Get this far and then it may be easier to troubleshoot your outside connection.

You need to access by External IP and work out the routing in your firewall/router. I use hardware VPN for this and it works and is vastly more secure.

I really appreciate your help, I've got to get this going before tomorrow, i'm going away and need remote access.
Security no concern, there's nothing of any value on the remote pc.

Your suggestion, 'try local before www' i'm trying, but this is where I have the problem with the names, i'm trying IPAddress/computername but I don't know which name...

Look in Computer, Advanced properties for the computer name. There is only one. Using IP address should avoid name resolution problems.

With Remote Desktop Connection, try just the IP address and don't include the computer name. It may think computer name is a folder. I do not need and do not use name when using RDP. I just use the IP address. That is the computer.

Thanks, I got it going.
you were absolutely right about no computer name, just ip address, apparently if you port forward to the pc hosting remote connection you're ok, and you have to add more ports and change the remote connection to access different pcs. Seems a funny way to do it,  like having all the pc's behind a hub access the network on a different port to distinguish them rather than just IP addressing, but then I know absolutely diddly about networks....
