VM Network Connectivity Dropped under high load

A while ago I posted about a hotfix that would correct a problem where virtual machine network connectivity would be dropped under heavy network load (original blog post here).

Unfortunately this specific fix was not included in Windows Server 2008 R2 Service Pack 1.  We have released a new hotfix to address this problem on systems running Windows Server 2008 R2 Service Pack 1.  You can download it from here:
