Dear All, I have spent 2 days trying to resolve a problem whose solution I have been unable to get inclduing researching on the internet. I have tried most of the solutions without success. I have re-installed exchange 2000 and whenever I mount the database I receive an error with event ID.9519 and the actual error is ID:c1041724 Exchange systems manager and the application logs gives the event id 9519 Source: MSExchangeIS I have tried checking on the data integrity and is fine. I have also checked the various security allocation to the folders and they are fine. I have checked to ensure the necessary 2 files (priv1.edb and priv1.stm) and available. Does anyone have a solution to this problem? Thanks Willy
