Hi All,
I am facing while installing the Microsoft SQL Server 2014 Express SP3, but If I uninstall the SQL components and re-run the script it install the SQL Server successfully.
I wanted to know why it is failing the first attempt when installing the Service Pack.
Below are the errors:
Login failed for user ‘Contoso\demouser’. Reason: Server is in single user mode. Only one administrator can connect at this time.
Any quick solutions would be recommended
