Limber ensures that a server's replica pointer table is updated when that server's server name or address is changed. Such changes occur when:
When a server is booted, the limber process compares the server's name and IPX address with those stored in the replica pointer table. If either are different, NDS* automatically updates all replica pointer tables that contain a listing of that server.
The limber process also checks that the tree name is correct for each server in a replica ring.
Limber runs five minutes after the server boots up and then every 3 hours.
