I have my own DNS server at home to access local names, and that is working fine.

Then I have my laptop, now obviously my laptop leaves the home now and then, therefore it accesses different nets outside my home, and my DNS server is not accessible there... So I figured that I would just add Google as secondary DNS...

But actually, when I do that, then suddenly I can't access my local stuff, the page won't resolve (at home that is, obviously), like my laptop is getting a quicker response from Google's DNS or something, because it can't find anything on the addresses I use locally.

If I then remove the secondary DNS, and keeps my own, then it works fine again...

So do I somehow need to seperate what DNS's to use on what nets? I already use sepperate DNS settings when I connect using my 3G modem, but when I use hotspots it seems to use the same settings regardless (at least in the train), also can it differ wired connections?... Is there another solution?

OS: Windows 7 Ultimate, x64
