Problem with 7.6 and Internet connectivity

I'm not sure that this is directly connected to the DisplayLink Ethernet driver. Our driver is layer 2 only and just passes Ethernet packets between USB and the Windows Ethernet stack. If you can ping the DNS servers, but they are not resolving the name, the problem is probably somewhere in the Windows network stack or in the network security.

It sounds like you are using this in a business. Is there some network security that will prevent unrecognised MAC addresses (which the dock will be) from resolving host names to prevent them getting network access?

You were spot-on about the network stack. Just so happens today I was having a ton of trouble using the USB Ethernet adapter on my Surface tablet and ended up having to do a netsh winsock reset to fix it. When I tried the docking station on the Venue again tonight, it got me thinking, so I double checked the ipconfig and noticed even though my gateway was there, it wasn't explicitly listing as my dns server, so I opened network adapter properties and thought to try manually configuring. Lo and behold when I try to open properties for tcp/ip, I get an error: "in order to configure this you must first install and enable a network adapter". Same error I was getting on my Surface earlier. So I ran the reset command and rebooted and now it's working. Weird that I would receive the same error on 2 different devices, both using USB emulation for virtual NICs, but if that hadn't happened earlier, not sure I ever would have thought to try that. Anyway, my bad. You guys are spot on. My fault for not paying more attention before I made this post. But hopefully if this happens to someone else it'll help give them an idea what else to try. Thanks for the reply.
