REF:
SQL Server 2000 (64-bit)
Differences Between 64-bit and 32-bit Releases (64-bit)
<skipped parts not about DTS>
Data Transformation Services (DTS) components for 64-bit servers are not available in this release. Note the resulting functionality changes:
A DTS package can be saved on the 64-bit server, and a DTS package can be run against a SQL Server 2000 (64-bit) dataset, but the package must run from a 32-bit machine that is set up with SQL Server 2000 tools.
The Copy Database Wizard will not be able to run on a 64-bit server or target a 64-bit server. Data migration from SQL Server 2000 to SQL Server 2000 (64-bit) is supported. Attaching a 32-bit database to a 64-bit instance is possible by using either the detach/attach or the backup/restore technique. You can move databases back and forth between 32-bit and 64-bit versions of SQL Server.
If you are using Meta Data Services (MDS) to store a DTS package, you must manage and store the DTS package on a 32-bit server.
Transformable push subscriptions are not supported. Pull subscriptions from a 32-bit installation of SQL Server 2000 should work with a 64-bit Publisher or Distributor.
