This is a very peculiar problem with a station on our network. The client pc is running Windows 7 Pro. What makes this problem interesting is that this client is the only node on the network that seems to be experiencing this proglem. When I try to ping a specific Win 08 server by host name, I get an IPv6 address and get General failure. But when I ping it's IPv4 address, it responds just fine.

My first thought would check the DNS server the name resolutions to see what would be going on, but the problem begs the quesion, why does the station get an IPv6 address back and fails as opposed to using the IPv4 settings (which are static btw). What gives? I am including a screen shot of trying the one specific server and failing while trying another server with success. All other nodes on the network don't have problems communicating with the server the one station is having issues with. Pingng: General Failure

probably firewall related. Can you disable that computers firewall to check? If this works, then maybe resetting defaults of the firewall might fix it... – Logman Jun 6 '12 at 15:22
Firewall on the machine is disabled. – hydroparadise Jun 6 '12 at 15:33
Is the "IPV6 Protocol" enabled under network settings on the target machine? – Diogo Jun 6 '12 at 15:50
@Diogo Yes IPV6 is enabled. Other machines on the network that are IPv6 enabled get ping responses via IPv6. – hydroparadise Jun 6 '12 at 16:02
Maybe you should set a static IPV6 address on target machine and test again, it could be happening due to a mask limitation, I mean, your sorce and target machines arent on the same IPV6 network. It is really weird, my next step would be installing a sniffer such as wireshark and debug each step of icmp ping request/responses... – Diogo Jun 6 '12 at 16:07

Found out through reading a couple of other posts that IPv6 is not exactly disabled by unchecking the protocal in the network adapter settings. Also, there's prefix policies built into windows that favors IPv6 over IPv4.

Turns out Microsoft has some tools that help with choosing presedence or choosing to disable IPv6 all together found on their site. Still not sure why I got the General Failure message in the first place, but at least I was able to fix the presedence using Microsoft Fix it 50410.

In my case, this actually propagated all the way down to the Cisco VPN client. It said that there was a network subsystem failure. It turns out that my wireless nic was getting an IP address and all, but when I tried to ping my router, it was giving me a General Failure.

I took a look at device manager, and there were a bunch of new Bluetooth items that did not have their drivers installed. That was odd, because I hadn't installed anything new. In fact, this is a laptop with built-in Bluetooth hardware.

I know that Bluetooth allows you to do PAN (personal area network), so I wondered if this was somehow taking precedence over my WiFi NIC. I disabled all of these items in device manager, and although no new drivers were installed for this 'presumably new hardware', this allowed me to begin pinging my router. I'm now using my laptop successfully to both get on the we and VPN.

I had a similar issue. I had to uninstall the AnyConnect mobility client.

I had a constant ping running and was getting the "general failure." to 8.8.8.8; as soon as the uninstall was halfway done I was back to being able to ping.

I would get this error after:

  1. Accessing a site.
  2. Connecting to my corporate VPN.
  3. Accessing the same site.

It didn't happen for all sites, just sites that we (the company) published. To fix it, I ran

ipconfig /flushdns
