That bites.
My wife's boss recently understood the need for something bigger than MS Access: it was slow, clunky,... but they stuck with it, even though it had WAY over 50'000 records, split in 13 different tables
They went to some other database type, which was faster, but when they deployed the world wide web interface for it, and had everything running "replication", it didn't work very well.
so they took it down.
So they just got an MS SQL server
(no, they weren't affected by "slammer", but the rest of the network was).
Now if they could only understand the benefits of a transactional database...
