Win 7 DNS failure - lockup while browsing internet (Bug?)
I had this occur in both my RC and the release that I have on two of my three PC's. XP PC's work fine.When using substantial bandwidth via the internet (i.e. streaming, downloading) I get the following: “Name resolution for the name dns.msftncsi.com timed out after none of the configured DNS servers responded.”When this occurs I can still connect via the internet by using IPv4 addressing or a cached domain name, but cannot resolve any further DNS queriesIf I do a ipconfig /release --- ipconfig /renew, I am up and running again for a varying amount of time until I get the same error on my browser or Outlook.I have searched high and low and have seen that this issue goes way back to the RC days... Anyone have an solution? DNS and DHCP is set in my router... so all the PC's involved get their settings from the same place. http://www.google.com/url?sa=t&source=web&ct=res&cd=1&ved=0CAYQFjAA&url=http%3A%2F%2Fsocial.answers.microsoft.com%2FForums%2Fen-US%2Fw7network%2Fthread%2F0588b3cd-917d-4f81-a2a8-a55bf2f005e7&rct=j&q=windows+7+timed+out+after+none+of+the+configured+DNS+servers+responded&ei=lxaLS_GtN8TGlAf4krTPAQ&usg=AFQjCNEUaq_DeRuPF1VsgN95NQqOgvb4NAhttp://www.google.com/url?sa=t&source=web&ct=res&cd=2&ved=0CA0QFjAB&url=http%3A%2F%2Fsocial.technet.microsoft.com%2FForums%2Fen-US%2Fw7itproperf%2Fthread%2F534a7384-4009-44db-900e-cdff92a92741&rct=j&q=windows+7+timed+out+after+none+of+the+configured+DNS+servers+responded&ei=lxaLS_GtN8TGlAf4krTPAQ&usg=AFQjCNEoZyId12sntS9xXLGsq0OekmNYrw Thanks for any assistance.-BeuiMCSE since NT3.5

Hi, First, I would like to confirm when the issue began to occur? Did it occur after installing Windows 7 at once or installing certain application? Here are some suggestions you can try: 1. Uninstall the current NIC driver and reinstall it in Compatibility Mode. 2. Restart the machine in Safe Mode with Networking and check the result. Does the issue persist in this mode? If the issue still occurs, please upload the Event log to the Skydrive ( www.skydrive.live.com ). Collect Event log ========================= a. Click "Start", input "eventvwr" (without quotation marks) in the Start Search bar and press Enter. b. Right click on "Application" on the left frame, choose "Save Log file As"; in the pop-up window, click to choose the Desktop icon on the left frame, input "app" in the "File name" blank, and then click save. c. Right click on "System", with the same method, save it as "sys". d. Locate the two saved log files on the Desktop and upload them. Thanks, Novak

Thanks for the reply.I have an HP PC using the Realtek driver and a home brew PC using the Via tech driver provided by MS during the installation...So you are saying that the autmated install of Win 7 did not install these correctly?Also how is the DNS failure tied to the NIC? Is it not bound to the protocol stack?One of the PC's recieves updates and the other does not.I did not install any matching software packages on any of the three Win 7 machines since installation. Not significant changes or changes that would be in sync between the two PC's have occoured before or since this problem arose.I still need to check out the safe mode test and get back to you with the Event files.-Beui

Hi, Since the NIC card is a third party product and the NIC card driver is not designed by Microsoft, the automatically installed driver may be not the latest one. I suggest you access the manufacturer website to download the latest driver and reinstall it. If there is no driver for Windows 7, please install the driver for Windows Vista instead in Compatibility Mode. Thanks, Novak

NOPE. Windows 7 was creating a second non existant DNS entry from the DHCP client. i.e. My Router/DHCP server is a Cradle Point CTR350. It exists as 192.168.0.1 on the LAN interface. Therfore DHCP provides for a DNS server address of 192.168.0.1 , but in my case a second DNS entry of 192.168.0.2 was showing up in the IPCONFIG /ALL screen. Because of unknown throughput issues, the first DNS entry is not reachable and fails over to the second non-existant entry, but nevers fails back to the first. By setting a static DNS entry of 192.168.0.1 and a secondary of 8.8.8.8 (Google DNS) I get around the problem for the time being. Regardless of which of the three Windows 7 PC's I use, this problem occours. I notice alot of throughput issues with 7, this may also be an issue associated with the reason for the failure to get a response from the first DNS entry. -Beui
