Hello,
I have upgraded several hosts from 3.5 to 4.1 and am having issues upgrading the virtual hardware on several 2008R2 hosts.
My steps:
Upgrade vmtools, this completes successfully. Server reboots and tools are installed and working fine.
Shutdown, upgrade virtual hardware. This completes, server reboots, but the Intel PRO/100MT NIC Is not loaded. It has a warning icon in device manager and states it is not working properly because Windows cannot load the drivers required. Code 31.
If I uninstall vmtools, reboot, restart again (Windows asked to), reinstall tools, reboot the server, uninstall NIC from device manager, scan for changes, the NIC finally loads fine.
Uninstalling the NIC from device manager and scanning for changes causes it to load with an error again.
Any idea on how to get it to work correctly after the virtual hardware upgrade? All the reboots make this a real pain.
