Can you tell me some, I wondering what complications you did find that I didn't find. Especially for lookuptables you don't have to worry about RI that much.

>Replication, even with SQL Server 7, is a pain. It introduces more complexity that has to be managed. With the SPT approach, if folks are hooked up to a wan, they can pull their lookup data from a central server, thus negating the need to replicate...Also, the Active Directory is a good choice in these scenarios..

How does active directory fit in here ?

Absolutely a 2. But as I said the two engines are not mutual exclusive. With the replication manamger I could replicate the some (lookup) data to VFP.
