Workflow and ServiceDesk Community

I am trying to set up new workflow server in a lab environment.  I started working through some of the basic workflow videos in the forum to do the install and start working in the workflow manager and modifying templates, etc... but I seem to be getting stuck on permissions.  If I open processmanager in IE I am getting the below error.  Does anyone know what is going on?  This is a new workflow install on the SMP server.  Thanks in advance.

Server Error in '/ProcessManager' Application.

Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

The application pool used by the ProcessManager more then likely doesn't have the necessary permissions to access your SQL server. If the SQL server is off box & you are using Windows Authentication to access SQL change the account used by the Application Pool in IIS to a valid AD account that has the proper permissions to the SQL server.

Thanks, I will try that.  The SQL is off box.
