Consider the following scenario. You configure an immediate updating transactional replication in Microsoft SQL Server 2000. The replication contains a table, and the table has hundreds of columns. In this scenario, the Distribution Agent may report the following error message: For a list of all publicly released SQL Server 2000 Post-Service Pack 3a hotfixes, see the following article in the Microsoft Knowledge Base:

This problem occurs when the synchronization trigger definition for an updatable subscription is longer than 4,000 characters. The internal buffer for the trigger definition is limited to 4,000 characters.

The installer does not install this hotfix correctly on x64-based systems. This installation issue occurs when the following conditions are true:

• The system uses the Advanced Micro Devices (AMD) AMD64 processor architecture or the Intel Extended Memory 64 Technology (EM64T) processor architecture.
  
  Note This issue does not occur on systems that use the Intel Itanium processor architecture.
• The system is running a 64-bit version of the Microsoft Windows Server operating system.
• The system is running a 32-bit version of SQL Server 2000.

We have corrected this installation issue in later builds of SQL Server 2000, starting with version 8.00.2244. When a customer who is running SQL Server 2000 on an x64-based system requests this hotfix, we will provide a build that includes this hotfix and that can be installed correctly on an x64-based system. The build that we provide will be version 8.00.2244 or a later version.
