Luis,
I have merge replication working between 2 locations and find it to work fine when it works. However, when it doesn't work you don't always know. Non-merge replication schemes are probably more tolerant, but you might consider some 3rd-party tools to periodically verify the replication.
http://www.red-gate.com/ has some good ones.
>I have a SQL Server DB that I want to be replicated in two other geographically distant buildings. What are the pre-requisites for the DB to be ready for replication? I want to use replication that updates, say, every 15 minutes data for all the DB tables.
