Had the same issue, however enabling NLB didn't overwrite the virtual machine MAC, it remained the same as it was specified on the host in Hyper-V. I created the cluster anyways, copied the mac down from the cluster parameters in NLB manager and then turned both nodes off and updated the MAC in Hyper-V with the MAC from NLB manager. Worked.

I should mention I was using Windows 2008 Enterprise R2 guest OSes and Exchange 2010 on Window 2008 Datacenter SP2 Virtual Hosts.

I was only using 1 VM for the NLB. I never added the second but it’s very simple to do so. MSExchange.org and Andy Grogan’s site both have excellent NLB walkthroughs.
