Some of our servers could not be added to the partition.
I used DSREPAIR - Advance options menu - Replica and partion operations and
got the following message:
This Server's DIB does not contain any replicas. This is a normal
occourence when replica distribution of partitions in a directory services
tree does not place any replicas on a server. Not that you should have at
least two replicas of every partition for fault tolerance. To perform
replica operations, run DSREPAIR on a server with repicas.
Program execution should continue normaly

Some one know how to fix this problem?
