    SET @srvname=@@SERVERNAME

    EXEC sp_dropserver @server=@srvname

    SET @srvname=CAST(SERVERPROPERTY('ServerName') as sysname)

    EXEC sp_addserver @server = @srvname , @local = 'LOCAL'

EXEC('DROP LOGIN ['+@NAME+']')

 

DECLARE @SERVERNAME VARCHAR(100)

SELECT @SERVERNAME=@@SERVERNAME

 

EXEC('CREATE LOGIN ['+@SERVERNAME+'/Administrator] FROM WINDOWS WITH DEFAULT_DATABASE=[master]')

EXEC(' master..sp_addsrvrolemember @loginame = N'''+@SERVERNAME+'/Administrator'', @rolename = N''sysadmin''')

GO

 

 

DECLARE @NAME VARCHAR(100)

SELECT @NAME=NAME FROM SYSLOGINS WHERE name  LIKE '%/SQLAGENT'---启动账号

EXEC('DROP LOGIN ['+@NAME+']')

 

DECLARE @SERVERNAME VARCHAR(100)

SELECT @SERVERNAME=@@SERVERNAME

 

EXEC('CREATE LOGIN ['+@SERVERNAME+'/sqlagent] FROM WINDOWS WITH DEFAULT_DATABASE=[master]')

EXEC(' master..sp_addsrvrolemember @loginame = N'''+@SERVERNAME+'/sqlagent'', @rolename = N''sysadmin''')
