Unable to remote desktop Azure VM when IP changed from Dynamic to Static (Public IP). Previously with Private IP Address and port number I was able to remotely access azure VM.

Answer 1

@Prashant Andhale Welcome to Microsoft Q&A, Thank you for posting your here!!

If you have another VM in the same network (Virtual Network or subnet ) of the problem VM please check the connectivity by taking RDP with Private ip of the Problem VM from the other VM and also check if you are able to access the VM form serial console.

Quick troubleshooting steps

After each troubleshooting step, try reconnecting to the VM:

1. Reset Remote Desktop configuration.
2. Check Network Security Group rules / Cloud Services endpoints.
3. Review VM console logs.
4. Reset the NIC for the VM.
5. Check the VM Resource Health.
6. Reset your VM password.
7. Restart your VM.
8. Redeploy your VM.

Hope this helps!

Hi @Prashant Andhale ,

As I can understand previously you were connecting the VM using private IP address and now is it public ? If you are connecting using public IP address then there might be a possibility that your network is blocking to take remote using public IP (Usually most organization do this). If you are using still private IP, then there should not be an issue if you just changed it to static. Just would like to know how you have changed it ? From Azure NIC level or within OS ?

Answer 3

I had a similar issue that a customer changed the private IP address after login in to the vm.
What i did was to:

Stop and deallocate the vm

Go to networking and click on "Attached interface"

You may need to create a new interface.

You can now delete the old NIC, if you want

You can then assign a new IP or use the existig public ip

I used these methods to resolved the issue.

Let me know if these method helped.
