Fix Windows Private Network Connection

Tumelo stayed with the project until it was satisfactorily complete. He stayed in communication the whole time. A few times his work slowed noticeably and some instructions were not clear but he did get to a solution. Because he used a notepad to communicate, I was able to keep his instructions for future reference. He made sure I could redo the tasks if necessary. I like that! :)
