Weird situation here. We have 50 brand new dell OptiPlex workstations running win7x64.
There are two Hyper-V servers onsite - server1 is running win2008r2 with Broadcom nic teaming (active/standby) and server2 is running win8 beta with built-in nic teaming (active/standby).
I have one workstation out of the 50 that all of a sudden just can't properly communicate with server1 or any of its guests - we just see massive packet loss between them. Flushing arp hasn't helped - I rebooted the entire network infrastructure the other night and that seemed to help for a bit, but now the problem has returned. I'm pretty stumped at this point.
Any ideas would be most appreciated! |

It's heavy packet loss - so some communication gets through. In Hawaii atm so no time to wireshark it. Going to move the box to win8server soon (I suspect nic teaming might be the issue) so we'll see if the issue survives that migration... |

The 2 big monkeys could be vlan or subnetmask.
Otherwise, start with wireshark/ netmon and see where the traffic is getting to or not!

Ya. Everything works great talking to other hyperv hosts/guests and other network hosts. Everything but this one physical box |

Have you done end-end testing on the network connection, ports, etc? |

They are all completely identical (default windows configuration hasn't been touched, all built from the same image, configuration all done via dhcp)... |
