The Local Security Authority cannot be contacted - Azure VM RDP Connection Error RRS feed

  • Question

  • Hello Everyone,

    We are facing issue in connecting to Azure VMs. Below is the error screenshot.

    Two days back, some maintenance activity was carried out by Microsoft team.  Post that, we couldn't connect to two of our VM's. Totally we have four azure vm's connected in the same Domain. Our Active directory server is up and running. Using one of our domain account we are able to connect to it. And another server is also up but we are able to login only  with one domain account say "myaccount' but not with others. To make sure, it is referring the Active directory for login,we changed the password of the "myaccount" in active directory server. But using the new password, we couldn't login and it is logging in with old one. And not able to connect our other two servers. It is giving the above error(attached snapshot). At the same time, when we try to connect these servers inside our AD server, it is giving the following error "The remote desktop couldn't find the 'VM  name' machine". Now we are completely blocked and couldn't do anything. 

    Can you please suggest some solutions if you aware. Thank you!

  • Hi,

    After setting a new password, subsequent Remote Desktop logons should work fine.

  • Hi,

    Do you mean setting new password for the user in AD?. If so, we have already tried this. And I went through the link "https://social.msdn.microsoft.com/Forums/en-US/393a2f0c-979b-42fc-b019-d10bf79c0fcc/the-local-security-authority-cannot-be-contacted-azure-vm-rdp-connection-error?forum=ssdsgetstarted". I'm little confused here. We are unable to connect to VM. In this case, how can we update the remote settings?

  • Hi,

    Your machine should still have a local administrator account (e.g. MachineName\Administrator), in which case you can login with the administrator account. In the RDP login prompt, you'll need to put the full user account (e.g., "MachineName\Administrator" where MachineName is your computer's name, otherwise it will default to "PreviousDomainUsed\Administrator").

    If the domain administrator account you where using has an expired password and the Azure VMs enforce Network Level Authentication, this prevents you from changing the password through RDP. You should be able to update the password by logging into the domain controller's VM,

    If the DNS settings are incorrect, the VM will not receive the update. You will have to RDP into the Faulty VM with the local administrator account and update the DNS settings and then run "gpupdate" in a powershell.

    If this doesn't work, I would recommend you to troubleshoot the Azure VM by attaching OS disk to another Azure VM. See details here.
