System.Security.Permissions.EnvironmentPermission

I have a little program that I wrote in vb.net v2 to process some stuff when
a user logs into the domain.

I have created a manifest for the project so that it would work for XP and
Vista and used mt.exe as a post build process to embed that into my .exe file:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<ms_asmv2:trustInfo xmlns:ms_asmv2="urn:schemas-microsoft-com:asm.v2">
<ms_asmv2:security>
<ms_asmv2:requestedPrivileges>
<ms_asmv2:requestedExecutionLevel level="asInvoker">
</ms_asmv2:requestedExecutionLevel>
</ms_asmv2:requestedPrivileges>
</ms_asmv2:security>
</ms_asmv2:trustInfo>
</assembly>

I also ran:
caspol -pp off -machine -addgroup All_Code -url
file://<ourdomainname>/SYSVOL/* FullTrust -name LoginStuff -description
"Login Programs"


When I try to run the app from the network I get this error:
************** Exception Text **************
System.Security.SecurityException: Request for the permission of type

IntPtr wparam, IntPtr lparam)
The action that failed was:
Demand
The type of the first permission that failed was:
System.Security.Permissions.EnvironmentPermission
The Zone of the assembly that failed was:
Intranet

I even tried going into IE and setting the local Intranet zone to contain
file://<ourdomainname>/SYSVOL/*

I'm missing something but I'm not getting what I'm missing. Anyone got an
idea for me?
