Error Applying New Virtual Network Changes

When you create a new switch and assign it a pyhsical Network card, you might see this error.

Error Applying New Virtual Network Changes

Setup switch failed

The switch could not bind to <physical NIC name> because it is already bound to another switch.

This might happen if you used this NIC with a switch before and later removed the switch. The physical NIC on the host is still connected to the switch Protokoll and cannot be added a second time.

Solution:  

Use NCPA.CPL on your host and check the properties of the physical NIC. If it’s already bound to the switch Protocol, uncheck this binding and try again.
