I am having problems with DNS server isn't responding messages in Windows 7. Having done a quick search and found other threads about the same thing, I tried the suggested fixes but am still struggling with no connection. It will stop working for a few hours, then will work for a few hours, then just suddenly randomly stop working again. I'm quite new to Windows 7, so am not sure if it is a Windows 7 problem, or something else entirely.

Is there anything obviously wrong with this?? :huh:

Do you have nVidia Network Access Manager installed?

It looks like you have one dead connection (Ethernet adapter Local Area Connection 2) and one working fine (Ethernet adapter Local Area Connection).
What do you have listed under "Network adapters" in Device Manager"?

Thanks very much for the replies, this is driving me mad I must admit because the connection is very unstable at best, and not working at all at worst.

Yes.

Microsoft Teredo Tunnelling adaptor [this has a little yellow exclamation mark, and under device status says "This device cannot start. (code 10)]
NETGEAR WG111v2 54Mbps Wireless USB Adaptor #2
NVIDIA nForce 10/100/1000 Mbps Ethernet
TAP-Win32 Adapter V9



I have the computer connected to the router via the ethernet cable at all times too. Any pointers that might help would be much appreciated. :huh:

Remove the Network Access Manager and see if it continues.

Thanks, just done so. Early signs are that it hasn't made any difference, but I'll give it an hour or two to see if things improve. :huh:

I assume, you're using Comodo Internet Security?

TAP-Win32 Adapter V9 listed in your network adapters section is virtual network connection for Open VPN.
When you install Comodo and you opt for installing TrustConnect, that will create TAP-Win32 Adapter V9 entry.

I suggest, you reinstall Comodo and opt out from installing TrustConnect and livePCsupport.

Thanks, will try that also (I do use Comodo on that PC yes).

After uninstalling nVidia Network Access Manager it didn't seem to make any difference. However, I decided to set the DNS servers back to automatic after that, and since then all is well. It's a mystery to me as chances are it'll not work tomorrow.

I'll try reinstalling Comodo as you suggest, and see if that helps. Many thanks. :huh:
