Sorry, kabal1234, I couldn't make this up if I tried

Forget a German site and go directly to the source through http://www.neowin.net/index.php?category=main but be prepared to authenticate your version of Windows. In other words if you have a pirated copy they will treat you differently. How? Don't know cause I am legal and just did this download today.

Yada yada yada, what a hero, give the man a medal

Ok, the solution, which is extremely simple is this:

Choose "Windows Firewall" in the in the Windows Control Panel and the there the tab "Exceptions". Select "File and Print Services" and click on "Edit". Now you can see four ports which are used by the file and print sharing service.

To lock the service to the outside and keep it open for the internal LAN, you have to individually select and change its area [to subnet]with the respective button.

That's it. The article in true FUD style was trying to make a big deal out of it:

A number of test scans run by PC-Welt revealed that this in fact is a common configuration and not a rare sight. Without great effort, we were able to discover private documents on easily accessible computers on the Internet. It must be assumed, that these users wrongly believe they are safe and that their sharing configurations are only visible in their network at home: Often, we did not even encounter password protection.

My PC was already set to subnet so didn't have the problem - and I think it's probably the case with most PC's....

hi'

last option ... use another firewall that the one fron MS

and if not sharing anything, just disable file sharing

if you share files, get a software that you will have to configure to the only subnet IP of your network.
