Thanks all! Cullen, as I was working on replacing the four files you referenced again last night, I noticed that Sage was running as a service, even though I had asked IT to disable it and start Sage as an app instead...I believe there may be a conflict with concurrent server processes, since the Application Server Startup is added to the Windows Startup menu AND the Service is running. We're going to switch back to just Service again, so we'll see what happens over the next few days, I guess.
