I have a Windows 2000 Professional workstation and Windows 98SE. Connecting via a Parallel is a pain. If I set the Laptop to listen, there seems to be no way for the Windows2000 workstation to get the correct username and password. If I set the workstation (Windows 2000) to listen, I get a connection which lasts for a while and then shuts down. There is a message in the Event viewer that says;<br><br>"A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate. No L2TP calls will be accepted."<br><br>Any advice?<br><br>Thanks guys!
