  • What is the OS of the server? That looks like an IPv6 address. – DanBig Feb 10 '10 at 15:36
  • It's Windows 2008 - I have DHCP set up for IPv4... We aren't using ipv6 at all.. or at least not intentionally – alex Feb 10 '10 at 15:37
  • Definitely IPV6 - ping -4 otto will force it into IPv4 mode. – MattB Feb 10 '10 at 15:40
  • ok, that's returned the response i was expecting... how can i set the "default" to IPv4?? Up until about an hour ago, pinging otto would of returned – alex Feb 10 '10 at 15:41

You may disable TCP/IPv6 of local area connection . I had same problem for a while ago. It did solve our RDP problem.
