We have a complex Access front end and a process that requires replication.
FWIW I've read that the reason for dropping replication support was that subsequent methodologies and technologies made it somewhat redundant. I'm referring to (for example) Terminal Services and apps like Citrix, which made it possible to access a TS or Citrix server where a db back end was on a LAN and the user could log in remotely to their own fe from anywhere as long as they had access to it. If it was due to web based Access db's as you say, then you'd have to wonder why support for web based Access db's has been dropped. It's interesting to note that the other technologies still provide a means of accessing an Access db remotely. So I wonder if your app really needs replication, or if you're not yet prepared to adopt any of the other technologies that would make replication a thing of the past.
The more we hear silence, the more we begin to think about our value in this universe.
