Why is my MVC app trying to log into my DB as my machine, and not as the App Pool identity?

When I try and access my newly deployed (to lcoal IIS 7.5) MVC4 app, I get the error:

Login failed for user 'DOMAIN\MACHINE-NAME$', where the '$' is appended and not part of the machine name. The connection string in web.config looks like this:

<add name="ComairRIEntities" connectionString="metadata=res://*/Data.ComairRI.csdl|res://*/Data.ComairRI.ssdl|res://*/Data.ComairRI.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=(local);initial catalog=MyDB;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
