| Description | Microsoft Exchange System Attendant was unable to locate the published copy of the public key for Exchange Server <server name> |
| Event Information | According to Microsoft: Explanation : When the Microsoft Exchange System Attendant service is started, it performs a consistency check to confirm that the public key for its server is correctly published in Active Directory. If this event occurs, the Microsoft Exchange System Attendant has determined that this server did not have a key published in Active Directory. To minimize any potential security risk, the Microsoft Exchange System Attendant will generate a new key pair for the server. User Action : Once the new key pair is generated, all passwords that are used by Exchange server components on this server must be re-entered using the Exchange System Management snap-in. This will include the Legacy Service Account password, SMTP/MTA passwords, and other connector passwords. Precautions should be taken to ensure that Active Directory is not being illicitly modified by unauthorized persons. |
