Network database

hi, wonder if you can help...

I want to share a DBF file on the network with two computer.  Both running
app. that require read/write/search to an indexed field.
But it seems that this is not possible with BDE !!!. The databse will not
be consistence or updated on the computers.  This is important as both
stations prompt user for a SERIAL NUMBER and this number cannot be
duplicated... HELP
