Hello Experts,
Help please.  I am using the Tailspin Spyworks application as a template.  I am still on xp pro.  I have visual studio 2010.  When I run the application using the developement version of localhost where it assigns a random port, it works fine.  When I bebug using IIS, I constanly get System.Data.EntityException {"The underlying provider failed on Open."}.  Anyone have any ideas.  Thanks,
Howard

Usually means a problem with your connection string, IIS can't access the database due to security problems (most likely given your symptoms).

Can you get the InnerException property details and if possible the innerException call stack it should provide more detailed information
