I have had an opportunity to work on sql replication technology with sql server 2005 standard most recently. It is not easy but doable. Your second paragraph on the NEED for it was also echoed by some replication guru. Your third paragraph touches on the requirements a bit more, which sounds like it's a unilateral replication (one way). Your fourth paragraph about concern of its performance, or probably latency, in my experience of merge replication (bidirectional) with a small network, it could be up to 1 minute or even longer for server to servers (one to many) full "sync", but your case could be server to client (one to one) I think so it would be faster. Approach-wise, I took/used the GUI/Wizard tool first to get everything working and then created and organized scripting to automate the process, which seems to work fine. I've also "play"ed with trasactional replication a bit and got it working as well but too bad I didn't have time to document it, it's supposed to be easier than merge. hih, Don Chunshen Li ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:319354 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
