Windows Server 2008, can’t ping, but networking is fine

I ran into this same problem on Server 2008, completely out of the blue. Tried the same steps as you also, with no luck. I ended up dumping the Winsock and Winsock2 settings from the registry from another (working) box and using those.

Download from here and here.

If you want to give it a shot, just back up HKLM\SYSTEM\CurrentControlSet\Services\WinSock and HKLM\SYSTEM\CurrentControlSet\Services\WinSock2 first to be safe. After you back those keys up, delete them from the registry, then import and reboot. Dumped from Server 2008 x86.

I know this is an old post and it surely got solved by now but I had a similar problem and I solved it in a very simple manner. Maybe this will help someone.

At me was even worse than this: I had 2 internal network clients loose conectivity to the internet(not only the computer with the reserved address) and it even disrupted the smtp communication for all clients.

You simply need to add the ip addresses assigned to you by your isp to the ip addresses on the interface connected to the internet: at the internet connected network adapter - tcp/ipv4 -advanced - ip settings - ip addresses - add .

That way the routes will be updated automatically and everything will work as it should.

Here is on the third step - first point:
