My client has a pdc that has a lot on it. I’m gonna change that soon. But until recently they were receiving e-mail quite nicely from their ISP, when someone tried to send them a large attachement and Exchange crashed. After rebooting the server they called on yours truely. The q’s were building on the ISP servers and could not get through to their Exchange server. I’ve stopped and restarted almost every Exchange Service I can find and just as the messages begin to download the IMS service stops. I start it again and it stops just as quickly. Any ideas? Please help!!!!!
