Dear EE,

I have tried many different password just to pass using SA account in SQL Server, but still failed.
How to know or reset SA password in SQL Server 2008 R2?

I can't add our BUILTIN\Administrator account be sysadmin, that's why we're trying to login in sa account. We our login using Windows Authentication (as default by our system)

Thank you in advance!

Fire up the SQL Server Configuration Manager and double-click on the SQL instance you need to reset.
Click over to the Advanced tab.
In the Startup Parameters, prepend –m; to the list to put SQL server into Single-User mode.  Click OK and then right-click on the SQL Server instance and click Restart.
Open up a command prompt, and type:
OSQL –S localhost –E
The –S parameter tells OSQL what server to connect to, and the –E parameter creates a trusted connection.  Capitalization of the switches does matter.
Inside the SQL terminal, type (substituting your new password for newPassword):
EXEC sp_password NULL, ‘newPassword’, ‘sa’
GO
Once that’s complete, type exit to quit.  Go back to the SQL Configuration Manager, remove the –m; from the Startup Parameters, and restart the SQL Server instance.

Make sure SQL Server and the browser are allowed through the Windows firewall, and try connecting from the other computer.

You can't find it out once it's set but if you're logged into SQL server you can reset it:

exec sp_password null, null, 'sa'

If anything relies on that account's old password it will break the connection for that application.

Start the instance of SQL Server in single-user mode by using either the -m or -f options. Any member of the computer's local Administrators group can then connect to the instance of SQL Server as a member of the sysadmin fixed server role

I got it already. I login as local admin & gotcha! Can add account to sysadmin server role.
Right-click to the database that I want to delete & select delete, it's gone!

But my main problem is still hanging at this moment, in whereas I also open it as another ID, regarding Shared Services Administration failure, with Sharepoint.

However, I know that your advise are helpful, so I would like to distribute the points to the 3 of you.
