SQL Server Service failed to start due to logon failure
Symptoms
When you restart SQL Server, SQL Executive, or SQL Server Agent, you may not be able to start the service and display the following error message:
Error 1069:the Service did not start due to a logon failure.
Or
Error 1069: Unable to start service due to logon failure
Reason
The password for the SQL Server, SQL Agent, or SQL Server Executive startup service account is incorrect because the password may have been changed.
Alternative methods
To resolve this issue, type the correct password in the SQL Server host's Microsoft SQL Server service account.
To correct the password in Microsoft Windows Server and Microsoft Windows XP, follow these steps: 1. Click Start, point to Settings, and then click Control Panel.
2. Double-click the Admin tool, and then double-click the service.
3. Double-click MSSQLServer, and then clicking the Login tab.
4. Type the correct password in the password and Confirm password text box, and then click OK.
To correct the password in Microsoft Windows NT 4.0, follow these steps: 1. Click Start, point to Settings, and then click Control Panel.
2. Double-click the service, and then double-click MSSQLServer.
3. Type the correct password in the password and Confirm password text box, and then click OK.
Note: Changing this password through the Services applet will allow SQL Server to reboot successfully, but if you have a Microsoft search (Full-text Search service) installed, it requires subsequent password changes through SQL Enterprise Manager (SEM).
