Virtual Server could not open its emulated Ethernet switch driver

December 1, 2008

If you’re here that means you’re probably having problems with MS VS 2005 R2.

I have a Broadcome NetXtreme GbE NIC (only one). Unlike blog posts found in top Google searches, my case didn’t involve any change of configuration that I know of. It just stopped working one day. I therefore used a less invasive approach:

a) Update the Broadcom GbE driver (broadcom.com)

b) Uninstall VM Network Services

c) Reboot the box and install VM Network Services again.

This worked for me. Maybe b & c alone would have sufficed.
