I have an application that uses remoting.
I have strongly named every assembly in the application.
I have granted FullTrust based on the key used for strongly naming.
(I did this by creating a code group with the membership criteria being the public key that the assemblies are signed with.)
I have done this on both the remote and local systems.

This application can be run from a local disk (no problem), a remote disk (network share - big problem) and from a web page where
it runs under IEEXEC (big problem)

The local application is designed to connect to multiple and arbitrary servers.  I can connect to any server if I run from my
local drive.  I can not connect to any server if I invoke through IEEXEC.  (Even if the IIS is on my system.)

The problem that I want to solve is the IEEXEC invocation.  If you look at the stack trace below find the line with the <<<<<<<<
on it.  This method returns a CAO.  I believe, based on other information, that the error is occurring on the actual return of the
CAO.  

My understanding of CAS keeps telling me that I have not setup the code groups etc correctly, but I THINK that I have.

Any insight would be helpful and appreciated.
