You can start, stop, and pause a server both automatically and manually from the Services applet in the Control Panel.
If you are running Adaptive Server and the Windows NT Process Viewer, and Adaptive Server is listed in the Process Viewer, you may not be able to restart Adaptive Server after you shut it down. This is because the Process Viewer holds some Registry resources, even after the viewed process is closed. Shut down the Process Viewer before you restart Adaptive Server.
