well, i confirm what i said above: in the win server i unchecked everything and added the Linux server IP/Port. on another PC i used the default configuration and it immediatly found and connected to both servers... So you have to disable the search on both sides, if one is able to search then it will find all the servers. EDIT: i would like to know how this peer cache is working, because since i have played with the settings now what ever i'm doing the win server and the clients are connecting each other
