Vista - Request for the permission of type 'System.Net.SocketPermission fa

Getting an error when attempting to use a .NET assembly. The assembly
appears to load correctly, but when I attempt to use it I get an error. My
code was functioning until I upgraded my workstation from Vista to Windows 7.
I also had another machine it worked on, but I installed all the recommended
update and now the code doesn't function on that machine either. In
troubleshooting I ran CASPOL.exe -security off. Even with this setting I get
the error. I'm new to using .Net assemblies in my powershell code so any
assistance would be helpful.

Error:
Exception calling "Connect" with "2" argument(s): "Request for the
permission of type 'System.Net.SocketPermission, System, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

Here are some details about the assembly that loaded ok.

I discovered my issue. I guess I had loaded the assembly with a network path
initially. When I attempted to utilize the assembly (loaded as a network
path) I received the error. When I changed the path to a local drive path,
it still wouldn't work... until i closed my powershell session. After I
closed my powershell session and reloaded the assembly with the local path it
functioned as expected.
