Using shared networking, with the VM running windows XP. I have a windows app that needs to maintain a tcp/ip connection to a server - either the host Mac, or another system. Whenever I start the app and make the connection, between 30 seconds and 5 minutes later, the tcp/ip connection is lost - even to the host Mac ! If I re-connect, the connection will then remain open. I don't have to re-start networking or the VM, just the application. If it wasn't for the 30-40 "click OK" boxes I get from the app when the connection is lost I would ignore it. Any ideas ?
