i am running firebird on a 2003 server and have xp pro clients, we use firebird for one of our library applications. The problem is that our firewall closes unused network connections after 15 minutes and cannot be changed, so when the user leaves their computer the db connection drops and the app looks like it is still running. I need to set up a keepalive on the client or server to stop the connection being closed.....

Any help would be greatly appreciated
