Dear All,

I am trying to apply a service update 10.0.31 in our DevBox (Cloud-hosted) in each attempt getting preparation failed issue.

Deployment getting failed on Preparation step itself. And when I download the logs/runbook, 0 KB file downloaded and nothing shown in that file.

We didn't changed the VM admin credentials till today.

In SandBox and Build machine (Cloud-hosted) the service update 10.0.31 got successfully completed.

Recently our admin team setup a VPN connection to access the RDP in that instead of computer name we are using ip address to connect the RDP with LCS VM admin credentials.

Kindly help me to resolve this issue, waiting for you valuable answers.

Thanks,

Jeevanandham S.

Sorry, we never changed the RDP password.

Yes correct they added VPN requirements to this cloud hosted environment, so the connection is not established and raised this issue to admin team.

Thanks for your valuable reply.

Hi Jeevanandham,

Did you today change the password for the admin user on this VM or not? Your wording has an open interpretation for that. If you changed the password, LCS is not aware of it anymore.

Did your admin team add VPN requirements to this cloud hosted environment? In that case, LCS might not be able to connect to the VM anymore. I would suggest contacting your admin team.
