I have got problem at Lotus Domino server 7.0.Last time my names.nsf are deleted and i solved this issues from restoring from the backup. At that time i think that is the human mistake. But now still now i got same problem. How could be the names.nsf will deleted automatically and sometimse some of the users are deleted from names.nsf.
What will be the possible causes and how could i fix this problem permanently.
