Alright, the other day I was installing SQL Server 2008 R2 (same problem occurred in 2008 as well), when I reached the point Server Configuration and supplied Service Account’s account name and password, I encountered the following errors for both SQL Server and Agent service.
- The credentials you provided for the SQL Server Agent service are invalid. To continue, provide a valid account and password for the SQL Server Agent service
- The specified credentials for the SQL Server service are not valid. To continue, provide a valid account and password for the SQL Server service
I tried all the solutions available and none worked for me. For instance, changing the password to complex etc.
The problem was, the machine on which I was installing SQL Server was joined to the root domain (xxx.gov) and the user accounts I was using to install SQL Server was created on sub.xxx.gov. I don’t know what can be done to use those accounts but soon after creating an account on the root with the same permission, eureka! it worked flawlessly.
