Why do I have Unidentified network?
Hello all! So I'm new to Windows 7 networking. And I have average knowledge on networking. So this is how my network is setup. Now my setup may seem strange, or not the best way, but it is what it is, and needs to stay like this setup. In XP I was fine, but Win7 seems to give me a little grief. I have three computers. One computer that I will call my MAIN computer, has a static IP address. This is the computer every time I reboot, it shows up as a Unidentified Network, and Public. It also gives me an error to no internet access. Now this network that I have has no internet access. I need this computer to be on a WORK network. I can get it to that, but it never stays. My MAIN computer is connected to a 24 port switch, that has DHCP enabled. My other two computers have DHCP enabled. They are set to a WORK network, and it stays like that when the computer gets restarted. It also shows it has internet connection. But it really doesn't. And again, I don't need internet access. Each of these two computers are hooked into thier own 5 port switch. From the five port switch, it gets connected to the 24 port switch. So my network has 3 computers, and 3 switches. the two computers are fine, it's the main computer, the only one with a static IP address. I can I get around this? Thanks! Rudy

Do you have the Bonjour service installed on your MAIN computer? You may not have installed it yourself, it may have been installed as part of another package, such as iTunes, Quicktime or Photoshop. If so, and you're not using it to connect to any Apple devices, disable it. If you do need it, update to the latest version. Older versions of Bonjour are known to cause just this issue with Windows 7.

Hi Bob, I do not have the Bonjour service on my main computer. The computer is pretty clean. I just have SQL, VS 2008, adobe reader and a few other programs. No apple stuff, not even quicktime. Thanks! Rudy

You say that the two computers that use DHCP don't have this issue? What type of device are you using as a DHCP server, could it possibly be a router? Could you post the results of an IPCONFIG /ALL from both the non-working and a working computer?

Hi Bob, I don't think it's the router. I had the exact same setup with XP and I didn't have this issue. Here is the info you requested. PV-Admin is my main computer. Here is another funny thing. If I have my wireless enabled, my local seems to work fine. But the conditions I have to work under, I can only have one network adapter enabled, and that is my LAN.

So here is something. I enabled my IPv6 on my admin computer, and it seems to be fine after several reboots. Thanks Bob!

No, I don't suspect your router, I was just wondering where you were getting your DHCP and DNS from. The only odd thing I see is the 0.0.0.0 in the DNS servers list on machine INMCPUNAME001, but since this is one of the PCs that's working properly I think we can safely ignore this for now. Since you're using a static address on machine PVADMIN, have you modified your HOSTS files to reflect this? Because it's not getting an address from your DHCP it's never being entered into the router's DNS tables. I'm going to assume that the reason you're using a static address is because you need the address to remain the same at all times. If so, you may have another option - you can create a DHCP reservation for that MAC address in your router and switch the machine to use DHCP. By creating the reservation you're forcing the router to assign the same address to the machine regardless of anything else. This is a DNS error BTW; basically your computer isn't communicating with the router's DNS service properly. My personal preference would be to use the reservation in this case, your circumstances may be different.

I'm glad you got it sorted. Sorry I wasn't more help.

That's a good idea. I think I will do that. Thanks! Rudy
