Cannot register Test Agent with Controller (Test agent is Azure Worker Role, Controller is local machine, Connected via Azure Connect)

Question

Hi there,

I am having problems trying to set up a load testing rig with a Windows Azure Worker Role registered as a Load Test Agent, with my local PC being the Controller.

The two computers are successfully connected via Azure Connect. 

I have a local account on my Controller which is an Administrator, TeamTestAgentService, TeamTestControllerAdmins, TeamTestControllerUsers.

I have a local account on my Azure test agent which is an Administrator. Both local accounts have the same name "vstestagent"

When trying to run the Configure Test Agent I get the following error:

"Failed to register this test agent with the test controller. Possible reasons could be that you do not have the right permissions to connect to the test controller MY-PC:6901, the log on account does not exist on the test controller machine, or a firewall is blocking the connection."

When I look at the actual error log, I see this:

I, 2012/03/02, 11:29:17.542, AgentConfiguration: Found agent is not configured on any controller.
I, 2012/03/02, 11:29:17.542, AgentConfiguration: Adding agent RD00155D424EA4 on controller MY-PC:6901.
I, 2012/03/02, 11:29:17.542, Adding agent AZUREINSTANCE running under MY-PC:6901 to controller MY-PC\vstestagent 
I, 2012/03/02, 11:29:17.542, Creating Channel
I, 2012/03/02, 11:29:21.623, CreateControllerObject: attempt 0, System.Security.Authentication.InvalidCredentialException: The server has rejected the client credentials. ---> System.ComponentModel.Win32Exception: The logon attempt failed
   --- End of inner exception stack trace ---

So it definitely seems like the agent is connecting to the controller machine, but failing some credential check. This is the part which is mystifying to me, since as I said, I followed some guides which said that the agent and controller both needed local account with the same username and password, this is the case.

Anyone got any trouble-shooting ideas?

Hi,

While I don't have direct idea about that exception, I suggest you refer to a series of blogs, the blogs are about how to setup load testing with agents running on Azure:

• Load Testing with Agents running on Windows Azure – part 1 (http://blogs.msdn.com/b/ricardo/archive/2011/04/08/load-testing-with-agents-running-on-windows-azure-part-1.aspx)
• Load Testing with Agents running on Windows Azure – part 2 (http://blogs.msdn.com//b/ricardo/archive/2011/04/18/10151166.aspx)
• Load Testing with Agents running on Windows Azure – part 3 (http://blogs.msdn.com//b/ricardo/archive/2011/04/08/load-testing-with-agents-running-on-windows-azure-part-3.aspx)

Could this guide you in the setup?

Best Regards,

Hi,

I didn't receive response about this issue, so I'm closing this thread, please check the above documentation while setup the test infrastructure on Azure.

Hope the issue will be resolved soon.

Hi Forrest,

I did manage to solve the issue actually. For whatever reason, when running the Test Agent config setup program, it cannot be run under the same user as the Remote Desktop User. Not sure why this happens but when I ran the setup under another user, via a scheduled task, the agent registered successfully with the controller.

Thanks :)
