Impersonate remote user account with WUApiLib

I'm trying to search for updates on a remote machine and all my attempts to do so with impersonation have failed stating that the username/password was not correct.

Here is a sample of my code. I've tried every LogonType available from SimpleImpersonation. 'System.UnauthorizedAccessException' is what is thrown whenever I try to call CreateInstance and my impersonated user never matches what it should.

I will state that I CAN impersonate local PC accounts and domain accounts but I cannot impersonate accounts that exist solely on other machines which is something I need.

Any help is appreciated!

    Console.WriteLine(@"Original User: " + WindowsIdentity.GetCurrent().Name);
    try
    {
        using (Impersonation.LogonUser("IP_ADDRESS", "USERNAME", "PASSWORD", LogonType.Interactive))
        {
            Console.WriteLine(@"Impersonating User: " + WindowsIdentity.GetCurrent().Name);
            var type = Type.GetTypeFromProgID(@"Microsoft.Update.Session", target);
            var session = (UpdateSession)Activator.CreateInstance(type);
        }                
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex);
    }
    Console.WriteLine(@"Current User: " + WindowsIdentity.GetCurrent().Name);
