Network Teaming Issues with Windows Server 2012 R2 in VMware Workstation

I have been using VMware Workstation for my lab for several years now. Using Client Hyper-V just does not cut it for me because I have been working with different hypervisors lately and need nested virtualization. But I have not been able to get network teaming to work in Windows Server 2012 R2. Now, I have finally traced this to the type of network adapters in VMware Workstation 10.

The first network adapter in a virtual machine in VMware Workstation is an Intel 82574L Gigabit Network Adapter. But the second network adapter is an Intel PRO/1000 MT.

Different network adapters in virtual machine

Unfortunately, those two types of network adapters do not offer the same features which seems to be the cause for my issue:

Different capabilities of network adapters

The VM configuration (.VMX) revealed different device types for the two adapters:

ethernet0.virtualDev = "e1000e"
ethernet1.virtualDev = "e1000"

The type can be changed manually but the VM must be removed from the console first. Otherwise the VMX file remains locked and changes will not take effect.

ethernet0.virtualDev = "e1000e"
ethernet1.virtualDev = "e1000e"

After booting the VM, it shows two Intel 82574L adapters:

Identical network adapters

Two of those adapters finally enable a working configuration of network teaming in Windows Server 2012 R2 unter VMware Workstation 10.
