Symptoms

Access denied error on a connect service object.
Moved a connect service object from our Dev environment to our QA environment and I am getting an access denied whenever I run the smartobject against it. Attached is the hostserver log.
"67360429","2015-07-27 13:35:33","Error","SmartObjects","10702","Error","SourceCode.SmartObjects.ServiceBroker ExecuteSmartObject]","10702 An error occurred in the ConnectService service instance. Could not load file or assembly 'xxxx.dll' or one of its dependencies. Access is denied.
 

Diagnoses

I suspect that the assembly did not get properly created.
 

Resolution

Restarting K2 blackpearl and K2 Connect services from Windows Services on the QA K2 server resolved the issue.
