See example below.

1. On Windows Start button type Services on search toolbar
2. Right click on DBSimLServer and open the Properties dialog
3. On General tab, change the Startup type option to Automatic (Delayed Start)
4. Then press Apply and OK button to close the dialog.

Just to note that after following the above you may need to also start the service by clicking start.
