Bug #: 470049 (SHILOH_BUGS)


In Microsoft SQL Server 2000, you can enable protocol encryption for all clients or for individual clients. The Force Protocol Encryption Server Network Utility option forces all incoming connections to be encrypted.

To implement protocol encryption, the driver must access the Secure Sockets Layer (SSL) protocol. Specifically, protocol encryption uses SSL application programming interfaces (APIs) that are implemented in Microsoft Windows NT. However, a problem occurs with Type 4 JDBC drivers because they are not permitted to directly call system DLLs. There is no library in Java 1.4 or earlier that emulates the protocol encryption behavior of SSL from Windows NT. If you do not apply this fix or SQL Server 2000 Service Pack 4 (SP4), SQL Server silently accepts connections from JDBC. This gives the false impression that the connections are actually encrypted. If the Force Protocol encryption option is turned on on the server side after you apply the fix, JDBC clients trying to connect to SQL server will not connect. This problem occurs because the current versions of JDBC drivers from Microsoft do not support SSL connections.

Note Because of file dependencies, the most recent hotfix or feature that contains these files may also contain additional files.

The following JDBC drivers do not support the SSL connection:

  • SQL Server 2000 JDBC Driver
  • SQL Server 2005 JDBC Driver 1.0
  • SQL Server 2005 JDBC Driver 1.1

After you apply this hotfix, you must use third-party JDBC drivers to connect to the instance of SQL Server 2000 if the following conditions are true.

Note The third-party JDBD drivers that you use must support the SSL connection.

  • The instance of SQL Server requires encrypted connections.
  • You enabled the Force Protocol Encryption option in the instance.
  • You use one of the JDBC drivers in the previous list.


If your JDBC application requires protocol encryption in SQL Server 2000, you must use another method of encryption, such as Internet Protocol security (IPSec), or use a suitable SSL-enabled Type 3 JDBC driver.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in SQL Server 2000 Service Pack 4.
