Lost connectivity to Azure VM after changing DNS to automatically obtain DNS

Question

Dear Comrades,

Lost connectivity to Domain Controller couldn't do Windows RDP. It was configured to use ip 127.0.01, I changed it to automatically obtain DNS IP.

How can I connect to this VM and revert this change?

Hi @Chetan Kumar

Thanks for reaching us.

Please reboot the VM. When you do changes to DNS, VM need an reboot.

I believe you have done changes on the VM OS level , Always try to do the change of DNS from portal or powershell on the NIC of the VM not on the OS level so it is easy for you to revert the changes.
