Question…

…if one just wants to check like this…
System.AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);

WindowsIdentity myCurrentIdentity = WindowsIdentity.GetCurrent();

if (myCurrentIdentity.User.IsWellKnown(WellKnownSidType.BuiltinAdministratorsSid))
{
//This is a local admin.
}
else
{
//This is not a local admin.
}

…then does one really need the line…

System.AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);

…???

I don’t know if you’ve tried this code in Vista, if not, you may be for a few nasty surprises.

I got “Request for Principal’s Permission Denied” or close. This Vista is a complete run around when it comes to security. I think it makes everything secure by simply welding all the doors solid.

I got into this thing as a diversion while waiting for other answers to materialize. However, I do want to establish a “subterrain” security tracking system in my major apps that will monitor things in the background for unexplained and unexpected changes in the system. It is a long term, slowly developing track.

Thanks – Alex

WordPress has stripped out the escape it should be

“,{0}\t\t”

But it will have no effect due to the new line, so simply have

“,{0}”

As the pattern.
