Hi @shaikamjad-1250

You can disable NLA

The remote computer that you are trying to connect to requires Network Level Authentication (NLA), but your Windows domain controller cannot be contacted to perform NLA. If you are an administrator on the remote computer, you can disable NLA by using the options on the Remote tab of the System Properties dialog box.

There are multiple reasons why NLA might block the RDP access to a VM

You can disable NLA thru azure portal from VM blade.
