Answer 1

if (System.Security.Principal.WindowsIdentity.GetCurrent().IsGuest == true)
   {
     //User is Guest
   }

Answer 2

That would depend entirely on how your users are setup. You could use group membership to determine if a user is a Guest or they might be using the Guest account (although some organisations might disable that one).

Answer 3

Here's an optimized version of what Barry said.

   if (System.Security.Principal.WindowsIdentity.GetCurrent().IsGuest)
   {
     //User is Guest
   }

Answer 4

Are you using Domain Auth? If you are using Domain Auth, get the current user details with

Environment.UserName or Enviroenment.UserDomainName;

and check if user is a member or not.
