SYMPTOMS

When use ActiveX Data Objects (ADO) through Active Server Pages (ASP) to connect to Microsoft SQL Server, you may receive the following error message:

Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC SQL Server Driver][SQL Server] Login failed- User: Reason: Not defined as a valid user of a trusted SQL Server connection.

CAUSE

There are two reasons why this error may occur:

• Integrated security is turned on in the SQL Enterprise Manager, and the Microsoft Windows NT account that is being used has not been mapped to a SQL account.
• The User ID in the connection string is invalid or blank.

RESOLUTION

To resolve this problem, ensure that the following conditions are met:

• The Windows NT account is mapped to a SQL account.
• The User ID in the connection string is valid and is not blank.
• Set standard security in SQL Server Enterprise Manager. To implement SQL Server standard security, follow these steps:
  1. From SQL Enterprise Manager, right-click the SQL Server name that appears in the Server Manager window, and then click Properties. (For SQL Server version 6.5 click Configure).
  2. Click Security Options, and then click Standard and Windows. (For SQL Server version 6.5 click Standard).
• The Password Synchronization option is turned off for that project if you are running under Microsoft Internet Information Server (IIS) 4.0.

STATUS

This behavior is by design.
