VM not connecting to network

Question

Hi all,

So I am hoping this will make sense in the form I am writing it but if not please feel free to ask questions. I have recently created a new VM on hyper v. I created a vSwitch on vSwitch manager. It is an external connection type using Microsoft Network Adapter Muliplexor Driver. While creating it Windows told me I needed to bypass LBFO Teaming deprecation which I did thanks to a helpful command. Doing all that I switched the connection type to the new one created and it is still not able to connect to the network. When I go into the network settings it says the Ethernet is enabled but I am unable to ping to the IP it provides. Again I might need to write more info so let me know if you need anything else.

Hi Kid_Silva_000093,

Hope you're doing well.

It sounds like you've taken the necessary steps to create a vSwitch in Hyper-V and configure it for external network access using the Microsoft Network Adapter Multiplexor Driver. However, despite enabling the Ethernet connection, you're unable to establish network connectivity from the VM.

Here are a few troubleshooting steps you can try:

1. Ensure that the network adapter settings within the VM's operating system are configured correctly. Make sure the adapter is set to obtain an IP address automatically (if using DHCP) or has the correct static IP configuration if using a static IP address.
2. Double-check the configuration of the vSwitch in Hyper-V Manager. Ensure that it's properly bound to the physical network adapter on the host machine and that the correct network profile (public, private, or domain) is selected.
3. Verify that the physical network adapter on the host machine is working properly and has a valid IP configuration. You can do this by checking the network adapter settings in Windows on the host machine.
4. Check the firewall settings on both the host machine and the VM. Make sure that the necessary ports are open and that firewall rules allow traffic to pass through.
5. Ensure that the drivers for the network adapter on both the host machine and the VM are up-to-date. Outdated or incompatible drivers can sometimes cause networking issues.
6. Make sure that the IP address assigned to the VM is not conflicting with another device on the network. Try assigning a different IP address to see if that resolves the issue.
