Symptoms

When you install Microsoft Data Engine (MSDE) version 1.0 or Microsoft SQL Server Desktop Engine (MSDE2000), the installation uses SQL Authentication by default. In addition, the default user name in these cases is sa, and the default password is blank.

Cause

This problem may occur when either of the following conditions is true:

The Microsoft Data Engine (MSDE) version 1.0 is installed with the following products:
  • Visio 2000 Enterprise Edition
  • Microsoft Visio 2000 Enterprise Edition SR-1
-or-

The Microsoft SQL Server Desktop Engine (MSDE2000) is installed with Microsoft Visio Enterprise Network Tools (VENT).

Resolution

Microsoft advises that this problem can pose a potential security issue.

To determine whether this applies to your system, try to log on to MSDE by using the OSQL utility from a command prompt. Use the following syntax:
C:\>osql -U sa -P
If you receive the following message
Login failed for user 'sa'
the sa password is not blank, which indicates that the issue does not exist on your system.

However, if you receive the following message after you run the command
"1>"
the security vulnerability applies to the system, and you must follow the steps in the next section to change the 'sa' password.

How to Secure the 'sa' Account with a Password

You can use the sp_password stored procedure to set up a password for the 'sa' account. For example, to change the 'sa' password from NULL to "Test!01", use code similar to the following:
EXEC sp_password NULL,'Test!01','sa'
To set a secure password on Microsoft Data Engine (MSDE) 'sa' account, follow these steps:
  1. At the command prompt, log on to MSDE as follows:
    C:\>osql -U sa -P
  2. When you receive the "1>" message, change the 'sa' account password by using the following command:
    EXEC sp_password NULL,'Test!01','sa'
    Note In this command, 'Test!01' is a secure password that meets your organization's security guidelines and that you can remember.

    Note The password for 'sa' account must be strong. For password advice, visit the following Microsoft Web site:

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
