A case where the server security dog caused the ASP.net web site to run wrong

Keywords in the dictionary: "registrypermission" added Keywords: "registrypermission" error, because the server on the security dog on the. NET program keyword too harsh lead to an error.

Today, I encountered a. NET error, and have not seen this error, and there is not much detailed information. Server error in '/' Application.

Keywords in dictionary: "RegistryPermission" added Keywords: "RegistryPermission"

At first thought is the permissions or DLL files have problems, and finally found that the server has installed a security dog problem

There is a. NET-related configuration panel in the security dog, which is changed to full mode with no permission restrictions, system default level
