I am writing an MS Access 2003 application which needs to execute a DTS package on the server from a client machine.
The following code attempts to execute the LoadFromSQLServer method on the created DTS.Package object.
The error "Invalid Class String" occurs at the "LoadFromSqlServer" line. The LoadFromSQLServer method executes successfully on my development
machine where the client and server are on the same machine.
Based on research on EE and the Net I have taken the following steps so far to resolve the problem:
* Manually copied over the DTS DLL and RLL files from my development machine to the test client machine and registered them as documented
in the "redist.txt" file on my SQL Server distribution disks. System Admin is currently getting the SQL Server install disks for me to
I can try to install the SQL Server Client Tools on the client to make sure that all DLLs and RLLs are present and registered.
* Found that the error may be due to the package containing unregistered Analysis services steps.
So I created a test DTS package that contains only a DTS Connection object. The error persisted.
As I said, I have attempted to research all applicable solutions on EE and elsewhere. Any suggestions out there?
I also have a more general question (or set of related questions):
When the LoadFromSQLServer method is executed, where does the package get executed i.e. where does the package execution process run,
on the client or the remote SQL Server? If on the client then do all executables included in the package command line tasks have to be installed
on every client from which the package is executed (thus making each client nearly as "heavy" as the server)?
Thanks for your help.
Client: Windows XP, MS Access 2003
