Hi all, I've been banging my head against my desk for a few days now trying to work this one out, hopefully someone can help me.
I've got some Dell Venue Pro tablets with Windows 8.1 running on them. They are connected to our domain via Ethernet (docking station) and function without a problem like that.
Now as they are tablets I want to be able to walk around the office with it and connect to Wi-Fi, so I pick up my tablet (tablet is logged on as me on the domain) and it disconnects me from the Ethernet network as the link is no longer there. I open up my wireless network or 3G connection and connect to that and browse the internet or whatever I want to do. I don't connect to the domain over the wireless connection, it's a separate network.
Now I come back to my desk and drop my tablet back into the docking station so the Ethernet port is now recognised again. At this point the Windows Firewall should realise that I'm back on the domain and put the 'Domain Firewall Policy' on, but it doesn't do that. Windows doesn't recognize that it's back on the domain at all. The network icon doesn't rename itself to my domain, sometimes it just sits and says 'identifying' and 'limited', sometimes it calls it 'Ethernet 2' or 'network 2' and puts that connection into the Public or Private Firewall profile.
I also have a group policy to disconnect non-domain networks when a domain network is connected, this doesn't happen either as it's not recognizing it's back on the network.
If I reboot the machine sometimes it comes good and recognizes it is back on the domain, sometimes it doesn't and remains connected to the WiFi and Ethernet.
In the event viewer I get messages that it can't contact the DNS servers due to timeout, I know that they can because they are there and all other machines are ok - they can ping them fine.
I've tried with static IP on the Ethernet (hard coded DNS as well) but it doesn't make a difference.
If I'm on the domain and remove my tablet from the dock but don't connect to a wireless network then when I put my tablet back in the dock it always works. So something about connecting to another network is screwing up the DNS recognition when I connect back to the Ethernet connection.
Anyone have this trouble before?
