I have a Windows 2008 R2 VM in my production environment currently with 2 virtual nics installed, one vmxnet3 and one e1000. I need to add a second vmxnet3 nic. The problem is when I add the additional vmxnet3 device windows recognizes the device, starts to load the drivers, then fails. In device manager the new device is shown as not working. Disabling and re-enabling the device does not fix the issue. I'm able to successfully add a second e1000 nic but I need to use the vmxnet3 driver to replicate my dev environment.
I suspect a reboot will resolve the device issue but I'd like to fix the issue without a reboot as the server is in my production environment.
Any ideas?
