How to protect the SMTP Windows Service with Service Protector

Step 1: Download and install Service Protector, if necessary.

Step 2: Start Service Protector.

Step 3: Select Protector > Add to open the Add Protector window:

Step 4: Add Protector

Step 5: On the General tab, in the Service to protect field, choose the SMTP windows service. It will be called Simple Mail Transfer Protocol (SMTP).

Step 6: SMTP Windows Service: General Tab

Step 7: If you find that your SMTP server occasionally crashes or hangs up after prolonged use, we recommend restarting the service daily at a “quiet time”. To do so:

Switch to the Monitor tab.
Check the At the following times box.
Click the Add… button to summon the dialog.
Specify a good time to restart the service, which should only take a few seconds. Every day at 3 AM works for us. (Note that you can choose to reboot the entire PC at that time if that is appropriate for your situation.)
Click the OK button to record your time.

Step 8: SMTP Windows Service: Monitor Tab

Step 9: Click the Save button. In a few seconds, an entry for the SMTP service will show up in the Service Protector window. The service may already be running but it is not yet being monitored and protected by Service Protector.

Step 10: SMTP Windows Service: Created

Step 11: Click on the green circle to see details of the SMTP service:

SMTP Windows Service: Details

Step 12: To start monitoring the SMTP service, choose Protector > Start “Simple Mail Transfer Protocol (SMTP)”. In a couple of seconds the shield icon in the Protected column will turn green to show that the service is being managed by Service Protector:

SMTP Windows Service: Protected

Click on that green shield to find out when monitoring started:

Step 13: That’s it! Next time your computer boots, the IIS SMTP service will start up automatically (as normal) and Service Protector will start monitoring the service to restart it quickly it if it crashes for any reason.
