DFS replicates some reparse points but not others

Hi,

I am using DFS Replication between 2 systems running Windows Storage Server 2003 Service Pack 2.  On the source system, the application files (*.EXE) to be replicated are stubbed (set to a 4KB reparse point that contains the file metadata and the actual data is stored on a removable RDX cartridge).  When DFS replication runs, it is able to replicate some of the stubbed files but not all of them.  I get an error 4406 that says:

"The DFS Replication service encountered an unsupported reparse point in a replicated folder. This reparse point will not be replicated because the replication of this type of reparse point is not supported by the DFS Replication service.

"

I've searched the MS-FRS2 document that explains that certain types of reparse points can be replicated but others can't.  So my question is, why can some files with a .EXE extension get replicated but others can't?  What else do I need to know about these .EXE files to help me understand why some won't replicate?

Thanks,
Paul
