RDP Error on Web and Worker Roles (Windows Azure PAAS)

RDP Error on Web and Worker Roles (Windows Azure PAAS)

I was working with a developer who had requested assistance on an issue. We were required to RDP to the role to troubleshoot further. While doing so we stumbled upon this RDP problem.  While we have known the reason for some time I was surprised that my searches on internet led to blogs for similar RDP errors on IAAS Virtual Machines. I couldn't find one right away for PAAS Roles (Web or Worker).  

So I thought of publishing one to help the users who might stumble upon this and would look on the internet to quickly resolve it and move to the actual work they want to do. The endeavor is to save you a few minutes of unnecessary struggle and frustration.

RDP would have been working fine for some time and you just can do it anymore. You go to the portal select the Cloud Service (PAAS Role) and the instance. Download the RDP file and give the password.

It give the error "An authentication error has occurred. The Local Security Authority cannot be contacted"

 It doesn’t fail immediately so RDP port 3389 is open in the local environment for sure.     

 It Secures the connection.

 Then starts Configuring it.

 

 Then it fails it the following error message

---------------------------

Remote Desktop Connection

---------------------------

An authentication error has occurred.

The Local Security Authority cannot be contacted

Remote computer: mycloudservice.cloudapp.net

The reason for this is that the certificate that was configured might have expired. The steps below guide through the process of resetting it. You can still use the same password as before so no need to change it though as a good practice you should change your password often and never have it on sticky notes below the desk.

Click the Configure tab.

 The date on the Certificate had clearly expired. As of writing the date is 22nd Feb 2014. 

 Set it to a future date. You can still use the same password (use a new one incase you have forgotten it)

Windows Azure now configures this new Certificate that was created. Once the configutation is over the new RDP file can be downloaded and used in the same fasion as illustrated in image 1 to 3. This time the RDP should be successful and you can proceed with the actual work that you intended to do on the instance.
