If you have ever had to the use Windows NET USE command in a batch file, like I have, you will have noticed that occasionally it will notify you of some potential problem and then hang waiting for a response from the user. This is aggravating but OK if you are running the batch file while you are sitting at the console, but it is a disaster if you are running the batch file in the background (as a scheduled task for instance). In the latter case, the batch file just sits there forever waiting for a response that will never come.
It turns out that there are two undocumented options for the NET USE command that will automatically answer those annoying messages with a fixed response. The two options are /Y and /N. These options will respond to all prompts with Y or N respectively, allowing the batch file to continue.
