I'm looking for a program that will allow me to seek out unauthorized shares on our company network. We've been having a big problem with users creating unauthorized shares, downloading MP3s, etc. and need a prog that will allow us to search LAN from a central location rather than go to each workstation (LAN is 100+ users). Is there any such beast? And if so are there any that are not costly or FREE, as funds are an issue.

Thanks in advance for any help.
