Answer 1

We checked the virtual machine from the boot diagnostics screen, and we could that it was stuck in a reboot loop, and we proceeded to create a rescue VM and attaching the faulty VM disk as an OS disk and we did the last known good configuration on the disk using the documentation below.

How to start Azure Windows VM with Last Known Good Configuration - Virtual Machines | Microsoft Learn
https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/start-vm-last-known-good

We swapped the repaired disk with the affected VM OS disk, and we confirmed that you were able to access the virtual machine successfully.

this might help someone.

Hi George,

Thanks for suggestions. Earlier I had mistakenly shutdown the VM. I have tried all of them but no luck.

I see error related to Virtual machine networking isn't accessible due to a networking platform failure.

I have tried below link, still no luck. VM cant accessible.

Please advice is there any solution?

hi @d365finops
Try to check in the boot diagnostics which screen your vm is on, if it's on the initial screen, try to connect via serial console and see if the nics are enabled.
