If the PC does not have the .NET SDK installed then the configuration tool will not be available via Control Panel -> Admin. Tools. Instead a command line tool CasPol.exe must be used:
The command line tool exists in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\
The command for setting Intranet as full trust is:
CasPol.exe -q -m -ag All_Code -zone Intranet FullTrust
