Hi Dave,

Thank you for using the community. From the exception information, it is
most likely the ASP.NET application didn't has enough permission to access
some resource, especially, the SQL server database. An ASP.NET application
will use a particular account to access the resource. By default, it is a
local account "Network service" with IIS 6.0. In IIS 5.0, it is "ASPNET".
In your enviroment, this account may not have enough permission to access
the SQL server. To get around this problem, you may use impersonate in the
application. For more information on this, you can refer to:

INFO: Implementing Impersonation in an ASP.NET Application

If you have any further question, please feel free to reply.
