You know that the logical, behind-the-scenes reasoning of why something won't work never matters to the average pc user. They will only see that their internet does not work, and they will blame Microsoft. This is my only point.
I understand the reasoning....all the more reason to send Feedback to Microsoft on the issue....the more reports of this nature the more able they are to solve the issue.

Update:

My issues have stopped. Well, almost....

My network icon works perfectly fine on my end - as it is supposed to - but it has been a while now and I cannot be sure if it was b/c of the clean install of the RC or if it was something else - my guess is that it was something else....

As for the adapter, it is a pair of Gigabit Ethernet ports that are on board from my motherboard - nForce network Controller.

The driver date is 10/17/2008, which leads me to believe that I may have, in fact, installed the nForce System drivers 15.25 to end the problems I was encountering - which sounds like the correct thing, as every time I have installed 7 the network gets flaky (as does resuming from sleep mode) until I install those drivers....

But I cannot be 100% sure....too much has happened in the last week and a half....

As for the almost caveat above: I have a D-Link DGL-4500 Wireless N GamerLounge router - updated to the latest firmware - and it is about as finicky as it can be. And I cannot downgrade to a stable f/w version b/c D-Link, for the first time that I have seen personally, has written the newer F/w's in such a way that downgrading is impossible....

So, the router will just stop working, but a power cycle makes it work again....

OK I'm assuming you've all got multiple NIC's.
And in ipconfig /all printout you've all got multiple gateways.
That's pretty bad right there.

Gateway is how you access the internet, so if you have TWO specified and one of them is a null 0.0.0.0... well take a guess at how confused windows gets with that.

It apparantly has 2 gateways, but only 1 network adapter to access it with and one of those gateways is null and void.

The NIC must be faulty; disable internet until the user runs the troubleshooter.

That's probably the chain of logic your PC is taking.

The preventative measure for now, is to disable ALL network devices you are not using.
So Right-click Computer, go to Device manager, then Network Adapters.

Disable all of them but the one you want to use.
That should stop the DHCP client being run for both adapters and generating two gateways.

Unfortunately Multiple Nic's is not the problem here. I am having this exact same issue, and I only have one NIC. I initially thought the same thing and even checked Devices and I correctly show only one NIC in the pc. My pc was working fine for since day one with Windows 7 RC 7100, then all of a sudden, two days ago I began to have this problem. I have to start Windows 7, open network and sharing center, select the "unidentified network" properties and choose to disable. I then run the troublshooter as admin, which re-enables the adaptor, Network and sharing now shows one network "Home" and I have internet access. If I restart, back to square one. The only things i have installed before having this issue were MS Office 2003, which i have since uninstalled, and Adobe CS3 suite. Nic Drivers are up to date as far as I can see, as Windows says i am using the most current drivers etc. I dont have the option to roll back either. Seems like this should have any easy solution, I cant seem to find one. I have googled this issue and have found that alot of people are having this issue now, but I have seen no real solutions aside from a clean install of the RC. Hope this gets sorted, I was happy with the OS!

On a side note, I am also running the Win7 RC on my Lenovo T400 laptop at work. This pc has one NIC also. I am currently typing this from it. On this pc I also have the "unidentified network" showing up. I am on a wireless connection, totally unrelated to my home pc network. The connected wireless connection status says "no internet access" and the "unidentified network" says "no network access" but I have full internet functionality with no limitations. Something is not right here.

Sorry, but there's just no two-ways about it.
For windows to be installing 2 networks, there must be two network devices installed.

Network sets are limited by the number of interfaces you have - you simply can't have multiple networks defined and interchange them between the one adapter.

Windows instead configures with an "Alternate Configuration" so if you want to inter-change network settings, you can with just a few clicks PLUS the alternate config acts as redundancy/backup if the primary settings stop working.

Proof. Virutal tunneled network interface.
Remember, virtual devices don't always show up in the hardware manager, they can exist just as an adapter and/or a simple protocol.

In windows 7 specifically, it could be say, the Link-Layer Topology Discovery protocols being errornously assigned DHCP settings.

Try disabling those for now, sadly that's the best chance at solving the issue i have atm since i don't have the bug myself and we're still in the manual trouble-shooting phases.

I do only have one physical Nic, but I did see another GUID assigned in my TCPIP section in the registry. When I get time tonight, Ill check my IPconfig and post it, maybe we can come up with something.

I posted this in another thread but I also have an nForce 680i board, dual nics, only one in use. Using both the W7 supplied 12/08 dated driver and the latest nforce driver set, I get this exact issue. On second reboot after installing driver, after dhcp has worked ONCE, it never works properly again, adding a 0.0.0.0 gateway to the list for the one in use adapter.

I believe that the 0.0.0.0 is a placeholder during the dhcp process and something is dying during the dhcp and the 0.0.0.0 is left hanging in the list.

Could be a bug in the /two/ nvidia drivers, though one is actually supplied by microsoft on disk. Or it could be a bug in the W7 dhcp code.

Using the nForce ethernet driver results in the other famous "loosing internet connection" problem, so now running with the W7 driver and static IP for now.

My Ipconfig on boot up with no internet access and then after I disable/re-enable adaptor is identical minus the Gateway. Before it is 0.0.0.0, afterwards it populates with the correct 192.168.1.2.

So somewhere upon boot up, Its losing the Gateway setting now. Not sure why.
