Dell R710
Windows 2008 R2 Enterprise Host
Windows 2008 R2 Guests
LOM1 - Management
LOM2 - Virtual Network 1 - 3x Low volume guests
LOM3 - Virtual Network 2 - Exchange 2010 guest
"Allow management operating system to share this network adapter" is off on both Virtual Networks
I will be connected to the Exchange 2010 guest via RDP and the connection will drop for 10-20 seconds. I am unable to ping the guest, but I can ping the host. I can ping other guests on the other virtual network.
When it happens, there is nothing in eventvwr.
I have turned off anything on the host and guest in the networking settings that says anything close to "offloading". Also did netsh interface tcp set global chimney=disabled on both the host and guest.
