- MORE INFORMATION
To learn more about Users, Groups, and Roles, see the SQL Server Books Online. To add Users, Groups, and Roles on an MSDE database, use the OSQL utility.
To change the SA account password on your MSDE database, follow these steps:
- On the computer that is hosting the instance of MSDE that you are connecting to, open a command prompt window.
- Type the following command, and then press ENTER:
osql -U sa
This command connects you to the local, default instance of MSDE by using the SA account.
- Type the following commands on separate lines, and then press ENTER:
Note Replace 'mynewpassword' with the new password.
Note that you receive the following message, which indicates that your password was changed successfully:Password changed.
Note We recommend that you install SQL Server 2000 Service Pack 3 (SP3) or SQL Server 2000 SP4. Service packs include more updates, and Microsoft Security Bulletin MS02-034 is included in the two service packs. For more information about how to obtain SQL Server 2000 SP3 or SQL Server 2000 SP4, click the following article number to view the article in the Microsoft Knowledge Base:
This is a cumulative patch that includes the functionality of all of the patches that have been released previously for SQL Server 2000. Also, this patch fixes the following three newly discovered vulnerabilities that affect SQL Server 2000 and SQL Server Desktop Engine (also known as MSDE 2000). (These vulnerabilities do not affect any previous versions of SQL Server or MSDE.):
- A buffer overrun vulnerability in a procedure that is used to encrypt SQL Server credential information. A user who is not authorized can use this vulnerability to gain significant control over the database. It is possible for the user to gain control of the server itself, but this depends on the account that SQL Server uses.
- A buffer overrun vulnerability in a procedure that relates to the bulk insert of data in SQL Server tables.
A user who is not authorized can use this vulnerability to gain significant control over the database. It is possible for the user to gain control of the server itself.
- An administrative credentials elevation vulnerability that occurs because of incorrect rights on the Registry key that stores the SQL Server service account information.A user who is not authorized can use this vulnerability to gain more rights on the system than system administrator has give to the user's account. It is possible for the user to get the same rights as the operating system. For more information, visit the following Microsoft Web site:Microsoft Security Bulletin MS02-035
SQL Server 2000 also includes the ability to record an unattended install to the Setup.iss file without your having to actually perform an installation. The administrator who sets up the computer running SQL Server can give a password to the installation routine under the following circumstances:
- If you set up SQL Server to have Mixed Mode Authentication, you must give a password for the SQL Server administrator account (the SA account).
- Whether you run SQL Server in Mixed Mode or in Windows Authentication Mode, you can require a User ID and a password to start up a SQL Server service account.
Note By default, for Windows NT and later, MSDE installs by using Windows Authentication. On computers running Windows 98, MSDE uses SQL authentication.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
By default, the value of the LoginMode Windows registry subkey is set to 1 for Windows Authentication. To turn on Mixed Mode authentication after you install MSDE, you must change this value to 2. The location of the LoginMode subkey depends on whether you installed MSDE as the default MSDE instance or as a named instance.
- If you installed MSDE as the default instance, the LoginMode subkey is located in the following registry subkey:HKLM\Software\Microsoft\MSSqlserver\MSSqlServer\LoginMode
- If you installed MSDE as a named instance, the LoginMode subkey is located in the following registry subkey:HKLM\Software\Microsoft\Microsoft SQL Server\Instance Name \MSSQLServer\LoginMode
- In Control Panel, open the Services tool, and then stop MSSQLSERVER and all other related services (such as SQLSERVERAgent).
- On the Start menu, click Run, type regedt32, and then click OK to start Registry Editor.
- Locate either of the following subkeys (depending on whether you installed MSDE as the default MSDE instance or as a named instance):
- HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft SQL Server\Instance Name\MSSQLServer\
- In the right pane, double-click the LoginMode subkey.
- In the DWORD Editor dialog box, set the value of this subkey to 2, verify that the Hex option is selected, and then click OK.
- Restart the MSSQLSERVER service and the SQLSERVERAgent service for this change to take effect.
