Initializeusingnotesusername: user is not a server error

I am trying to initialize a notes session on the Domino Server. I have just granted ASP.NET administrative rights on the machine. (I’ll trim it down later to see exactly what it does need and what it doesn’t… after I have the app working).

When I initialize the session using the initializeusingnotesusername method I receive this error:

User Adornotes Administrator/ADORNOTES is not a server

the code I am running to initialize the session is:

nsess.InitializeUsingNotesUsername(“Leave Request”, “”)

If anyone knows exactly what this error means and how I can resolve it, I would be greatly appreciative. Thank you.
