Check the following list for possible causes and potential solutions for this message.

• If the server is running antivirus software, the file may have been removed by that software. Set the server's antivirus software to exempt folders used by DAOS, and restore the missing file from backup.
• The specified database was restored from backup, but the referenced .NLO file(s) were not restored. Use the Tell DAOSMgr ListNLO command to identify missing files for the specified database, and then restore the files from backup. Depending on the number of DAOS references, the Resync command may take time to complete, and is best run at a time when the server is not in active use to avoid compromising performance.

  Tip If backup copies are not available, and if encryption on .NLO files is not enabled, it may be possible to copy missing files through the operating system from another Domino server. However, this workaround is not useful if encryption is enabled, because the .NLO files will be encrypted with the key of the other server and therefore unusable on the current server.

• The specified database was copied from another server through the operating system, and may contain tickets for .NLO files that exist only on the other server. Delete the database and use the Domino Administrator client to copy the database file from the other server. Copying through the Administrator client properly adjusts DAOS references so that they are correct for any .NLO files that exist on the current server, and they do not specify nonexistent files.
• The storage location specified for DAOS files (the repository) is inaccessible. There may be a temporary power outage, powered-off external drive, lost network connection, or similar problem with the machine or device. Check the availability of the device specified for storing DAOS files, and that the specification for it is correct in the Domino Server document. If no such problems exist, check to see that the .NLO file itself exists, and if it is missing, try the approaches above.
