I ran across an issue like this on a workstation earlier in the week. I found the thread that said McAfee had an issue with an update, followed the instructions, and was up an running on the workstation in no time. When I got home today, I have two laptops that connect to the home D-Link network via wireless. Laptop A is working fine, the one I am using now, and laptop B has no internet access, says the DNS server is not responding. I had McAfee installed on laptop B, so since I could not get out to update McAfee, I just uninstalled it, rebooted, and I still have no internet access. I have compared the ipconfig /all on laptop A and B and they are the same. Both laptops are running Win7 64-bit and I will post the ipconfig info from laptop A below. I did do a ipconfig /flushdns on laptop B, did not help. Just not sure what to try next... Thanks!

Well, I turned off the laptop B that had the issue and let it sit for about 4 hours. When I came back to it to install the program you suggested, when I started the laptop up, it had a working internet connection. So, I am not sure what fixed it, but I am able to surf the interwebs... Thanks for your assistance!

Well, I guess I spoke too soon. I cleaned up some stuff on the laptop B, did a reboot, and now I have no internet access. I am connected to the wireless network, but have the DNS issue back. I copied the file you suggested to a flash drive, ran it on the laptop B, and rebooted, and still no internet access. Any other suggestions?
