It is clear that something happend on the machine where you run the project. Some changes or settings were done on .NET Framework or on the securiy policies.
1. Code Access Security Policy Tool (Caspol.exe)
Allows you to examine and modify machine, user, and enterprise-level code access security policies.
Note: Caspol.exe can be found in "%windir%\Microsoft.NET\Framework\v1.1.xxxx" where xxxx is the build number of the .NET Framework you are using.
Permissions View Tool (Permview.exe)-Displays the minimal, optional, and refused permission sets requested by an assembly. You can also use this tool to view all declarative security used by an assembly.
Check for ASP.NET.
2. Go to Control Pnael->Administrative Tool->Microsoft .NET Framework 1.1 Configuration.
Expand RunTime Security Policy and there Entrprise, Machine and User.
You should know how to modify these features. Machine changes will be stored in c:%windir%\microsoft.net\framework\v1.1.4322\Config\machine.config file.
