Answer 1

Hello,

1、Check Event Viewer Logs

Open Event Viewer on the host machine:

Press Win + R, type eventvwr.msc, and press Enter.

Navigate to Windows Logs > System and Windows Logs > Application.

Look for errors or warnings related to Hyper-V or the VM.

2、Ensure Network Connectivity:

Verify that the VM is connected to the correct virtual switch in Hyper-V Manager.

Open Hyper-V Manager, select the VM, and check the Network Adapter settings.

Test Network Connection:

Log in to the VM (if possible) and check the IP address using ipconfig.

Ping the host machine or another device on the network to test connectivity.

Reconfigure Virtual Switch:

If the VM is not getting an IP address, reconfigure the virtual switch:

Open Hyper-V Manager.

Go to Virtual Switch Manager.

Ensure the virtual switch is set to External or Internal (depending on your setup).

3、Ensure both the host machine and VM are running the latest updates:

On the host machine:

Open Settings > Windows Update and install any pending updates.

On the VM:

Log in (if possible) and check for updates.
