  1. On the machine with Blackbaud Web Services installed go to Start > Control Panel > Administrative Tools and select Services
  2. Find Blackbaud Web Services in the list

  5. If the Status does not say "Started", right click on Blackbaud Web Services and choose to Start it
Note: While in Services, right click on Blackbaud Web Services and select Properties. Ensure the Startup Type is listed as Automatic so that it starts automatically in the future, if this is not already selected.

For versions at or above 1.4.14350.1 of Web Services: 
  1. Log in to The Raiser's Edge on the machine with Blackbaud Web Services installed
  2. Click on Web Services in the navigation bar
  3. Click on Blackbaud Web Services
  4. In the Configurations Options screen, click the Stop button to stop Web Services if it's running
  5. Click the green Start button to restart Web Services

A few things that will prevent the integration from connecting:
  1. If Blackbaud Web Services for the RELO Integration is installed on more than one machine, the integration may not connect. To fix this you will need to uninstall Web Services on both machines, and then reinstall it on only one machine.
  2. If the Raiser's Edge Mobile Events Management is installed on the same computer running the RE/LO integration it will prevent the integration from working (for certain earlier versions of the Blackbaud Web Services). Please refer to this solution for more information.
  3. If Web Services was uninstalled and/or deactivated from your local network this can update the integration GUID (A global unique identifier used to connect your RE and LO. The GUID can be found in the RELO plugin. Click RELO>Options>About and note the Web Service URL). You must contact Luminate Support with the updated GUID to reconnect Web Services with Luminate.
