- Verify the trust relationship between the two servers
- Verify the SQL permissions as if it works one way (read from the source/write to the destination) and not the other you might miss the write permissions on the destination
- Verify the Folders permissions in the DS Console as if it works one way (read from the source/write to the destination) and not the other you might miss the write permissions on the destination
- Verify the Share permissions (most likely "express" share) as if it works one way (read from the source/write to the destination) and not the other you might miss the write permissions on the destination
- look in th elogs to see if there are any erros:
. aexengine.log on both servers
. IIS logs
just some ideas?
