How to change the DNS of Vnet and virtual machine created in Azure to on-premises DNS

Question

We become indebted to.

When changing the DNS of Vnets and virtual machines created in Azure to on-premises DNS,

Changes on Azure

Virtual network → Overview → DNS server and

Network Interface → DNS Server → Custom

Will entering the IP of the on-premises DNS server in the 2 settings solve the problem?

On-premises and Azure communicate using ExpressRoute.

Also, will there be any changes to the virtual machine when changing the above two settings?

(RDP suddenly crashes, restarts automatically, etc.)

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you would like to update your DNS of VNET to use OnPrem DNS Servers.

Yes, the configurations you've made is correct.

To update VNET:

• Virtual network → Overview → DNS server

To update NIC:

• Network Interface → DNS Server → Custom

There will not be any changes to the VM, however, for the settings to apply:

• You must restart your VM

Thanks,
