Windows based systems running either Windows 2008 R2 or Windows 7 guest operating system configured with the VMXNET3 virtual network device in vCenter Server have one known issue. When a provisioning operation is done like cloning a VM, the target system gets new device and interface names (this name is the original name as is on the source system but with an incremented index suffix, like Local Area Connection #2 instead of just Local Area Connection). To prevent such issues and keep the original device and interface names as is, following the provisioning operation, you need to apply the Microsoft hot fixes for the specific operating system type that you are using.
