I created a Virtual Machine in Windows Azure (Windows Server 2008).

Accesed using remote desktop connection and opened cmd.

Then tried to ping 8.8.8.8 (which I can from my computer) but I got:

Pinging 8.8.8.8 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Ping statistics for 8.8.8.8:

Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

I do have internet access, because I can navigate using iexplorer to google.com or facebook.com (examples)

Question: What is happening that I cant ping?

I tried this and it didnt work:

ICMP is not routed by Windows Azure's load balancer / firewall, according to this MSDN forum thread. I'm fairly sure this is correct, as I've seen other posts about this, and I just tried as well (producing the same time-out messages). Ping will work between instances in the same deployment, assuming you've enabled inbound ICMP.

Someone on the above-mentioned thread mentioned using Mark Russinovich's PsPing which supports tcp-based latency testing against a specific port. While it's not ICMP, it at least provides an alternative.

Also: If you create a VPN connection between Windows Azure and your on-premises network, ICMP should work fine over the VPN connection.
