Hmm I would download http://www.tamos.com/products/commview/ And join the server. If you cannot than run it on the computer hosting the server. This should allow you to see anyone's IP who may be accessing/ screwing with your server. You can then Ban/ block their Ip's.
Watch a video on how to use it also
