I am also having asimilar error. I too used the Apache2Triad install and am getting this error when I try to start the server: I have uninstalled Apache2Triad after killing all processes. I restarted, cleaned my registry. Restarted again. I double-clicked start.bat and got this error. So I exited it and used stop.bat. Nothing. Still gives me the error. I check the task manager and can't find a thing...
