Caspol is used to setup trusts for .Net applications. But the command line version to view what has been done is not user friendly. A way to view trusts that have been setup can be found in the Microsoft .Net Framework Configuration 2.0 tool. That tool is installed with the .Net SDK. Note: this tool will not be listed in the SDK folder but a shortcut will be added to the Administrative Tools folder on the Program Menu.

Once it is running, check for your trusts that you have setup by looking at this folder

.Netframework 2.0 Configuration\My Computer\Runtime Security Policy\Machine
\ Code Groups

That should list all remote assembly(ies) that one has caspol setting up a trusts for… Note those don’t have to be assemblies but can be a full directory to trust.

By looking at All_Code\LocalIntranet_Zone one can see the pathing to your server as an URL. If you named the trust, it should be easy to find.

Debugging Trust Issues

If when debugging a trust issue, one needs to find the assembly in question as a listing such as \\Server\directory\MyAssembly.dll or within a listing such as \\Server\Directory\* . If that is not found, then trust needs to be setup using CasPol.

Suggestions

  1. One can temporarily turn off caspol security by opening up a DOS shell and typing caspol -s off. While the window is open, caspol will be turned off for debugging purposes. Once the window is closed it will be turned on.
  2. If one has remote assemblies on an intranet directory, one can set the whole directory to be trusted by specify a * when using caspol instead of an assembly or executable. That way if there are multiple assemblies within that directory, you don’t have to specify trust for each one.
