How to check whether a person has shared a file from Intranet to Internet?


Read this thread to know the step by step procedure to check whether a person has shared a file from Intranet to the Internet.

When I put the IP of a system in run command, I can check which file is shared on the Network. However, I would like to know if there is any other way through which I can check whether a file has been shared on the Network.
