Running the Service Configuration Utility is the only supported way of changing the stored monitoring service credentials. Changing the security account using the services applet in the Windows Control Panel causes the service to fail and isn't supported. The service appears to be running, but is unable to perform any work due to an encryption error.
Do not use the Service Configuration Utility if you are using the EPI version of SQL Sentry. Refer to the EPI Commands article for instructions on using the update command to change a password or service account.
The Service Configuration Utility is used to change the stored credentials of the SQL Sentry monitoring service. If the user account used by the monitoring service needs to be changed, the SQL Sentry Service Configuration Utility needs to be run for the public/private key encryption to validate the change. The ServiceConfiguration.exe utility is in the SQL Sentry program group on the Start menu. Change your SQL Sentry Monitoring Service credentials by completing the following steps:
1. Run the SentryOne.App.MonitoringService.Configuration.exe application to open the Set SQL Sentry Monitoring Service Login window.
2. Enter your new password, and confirm your password in the applicable boxes on the Set SQL Sentry Monitoring Service Login window. Select OK to confirm your changes.
3. If you have more than one SQL Sentry connection, you will see the SQL SentryDatabase Connection Management screen. Select the Connect button for the SQL Sentry connection you are updating.
4. Press any key to exit the Service Configuration Utility.
Success: If everything completes successfully, a Service configuration complete message displays on the Service Configuration command prompt window. Press any key to close out of the utility.
If you are using Group Managed Service Accounts (gMSA) for your monitoring service account, use the Is gMSA? checkbox. Follow the same process as described above in the instructions. When Is gMSA? is checked, the password fields are disabled.
See the isGmsa section of the EPI Commands article for instructions and examples. EPI allows gMSA to be used during the installation and updates to the account.
