Try a batch file with this text:
net stop silverappserverservice3.7
pause
You can also start the service by replacing the word "stop" with "start".
You can start and stop any service in Windows NT using the same syntax. The trick is to find the service name. To do this, open the registry editor and go to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
The folders under this key are names of services that you can start and stop. If you look close, you find the command line that the service is using, so you could presumably change it, along with the name that is displayed in the Services control panel applet. Also, you can adjust which services it depends on, but that gets harder.
Good luck.
