Hyper V, multiple guest OS's, public IP's and child partition can't communicate RRS feed

  • Question

  • Sorry to crosspost from TechNet, but I am curious if anyone here has a suggestion for me.

    I have Windows Server 2008 with Hyper V installed and windows firewall disabled. I have 4 Windows Server 2003 x64 SP2 child partitions installed. They all have integration Services installed. They are all hooked up on a virtual network that is running against my external adapter on my parent partition. All of the child partition OSs recive IP addresses from the public DHCP server and can access external computers. However no external computers can access the systems installed on the child partitions via thier IP addresses or host names. (they show up in DSN Records, they just cannot be pinged or connected to via SMB) Additionally no child partition can contact any other child partition. This worked fine on virtual server. The host operating system is connected to a domain. The 4 Windows server 2003 OS's in the child partitions are going to be thier own domain. The OS's in the child partitions cannot be even be pinged from anywhere except an internal command prompt window. Did I set something up wrong or is this a known issue?

    The following is the output of ipconfig /all for one child and the parent.
