Problem of navigation over IE with Windows Server 2012

Hi everybody,

I have 2 VMs (Windows Server 2012 Standard), the 1st one for the DC & DNS, the second one for the RDS, that use the same virtualized network card to communicate, and a CISCO ISA570 router.

Very classic :

DC :

IP : 192.168.110.100
Mask : 255.255.255.0
Gateway : 192.168.110.1
DNS : 192.168.110.100

RDS :

IP : 192.168.110.150
Mask : 255.255.255.0
Gateway : 192.168.110.1
DNS : 192.168.110.100

On the DC, the DNS use as redirectors the right DNS. I have also tryed to put directly the IP address of the router as redirector. I have flushed the DNS cache on both servers.

On both, I try to ping "www.google.fr" or anything else and it works perfectly, but impossible to navigate on Internet. It tells "waiting for www.google.fr for example".

When I put directly the IP address of Google in the IE address bar, it works.

I don't understand.

Any idea ?

The Cisco or any other hardware switches is where I would look next.  Make sure there aren't any VLANs that aren't supposed to be set up in place.  Also make sure there isn't some weird config on the ports on the switch like a trunked port, hybrid port, etc.

Try this:

1)  Open Internet Explorer
2)  Navigate to Internet Options
3)  Click the Connections tab
4)  Click on LAN settings
5)  Make sure automatically detect settings is checked

In fact, i have progressed. When I switch the VM on the second host, it reached the internet without any problem. When I am on the 1st host of my CSV HYPER-V Cluster, ping work but navigation fails.

I have removed the vNetwork connection and created it again. No luck.

I have changed the network wire, no luck too.

Maybe the integrated switch port of the CISCO router ?
