I tried to install SP3 on 2 instances APP1 and APP2 using unattended install. After installation, i could not start the services from Configuration manager. Also Hotfix.log file shows the following :
MSP Error: 29534 Service 'MSSQL$APP1' could not be started. Verify that you have sufficient privileges to start system services. The error code is (1069) The service did not start due to a logon failure.
From where can i enable to get sufficient privileges. Can someone give the steps please.
