[App_rpt-users] delete servers

Hi, The configuration of my servers is wrong and I'm told the only way to fix it is to delete both servers & nodes and start again from scratch. Unfortunately no one can tell me how to delete the servers, so I'm in limbo. I can connect to other nodes ok but no one can connect to my node MB7ICE they get (connection failed) Can anyone help?
