Enable NLB in a Hyper-V Guest
If you work with Exchange 2007 or Terminal Services/Remote Desktop Services in any anger, you’ve probably had to use Network Load Balancing (NLB) to balance services. For example I use it for the Client Access and Hub Transport roles in Exchange 2007, and to balance requests across my Terminal Services (Remote Desktop) Gateway servers. However, when virtualising these services, I found that Hyper-V doesn’t always play nice with NLB.
