Here is what I did in a new test;

1. I copied your code to a new web application on IIS 8 on Windows 2012 machine
2. I enabled Windows authentication in IIS
3. I created a new Credential, a Windows user on the remote machine
4. I configured VisualCron to use NTLM (again with the latest version) and selected the new Credential
5. I ran the Task and I got the redirect message in output and no errors

I can make it fail if I do any of the following:

1. select no Credential
2. select the wrong Credential
3. user other authentication than NTLM (if that not matches the authentication on the web application).

OK -- thank you for running the test. Let me get the latest beta and try it out.
