Event Type: Error
Event Source: MSExchangeIS
Event Category: General
Event ID: 9518
Description:
Error 0xfffff764 starting Storage Group /DC=LOCAL/DC=DOMAIN/CN=CONFIGURATION/CN=SERVICES/CN=MICROSOFT EXCHANGE/CN=FIRST ORGANIZATION/CN=ADMINISTRATIVE GROUPS/CN=FIRST ADMINISTRATIVE GROUP/CN=SERVERS/CN=NRLAEXC2000/CN=INFORMATIONSTORE/CN=FIRST STORAGE GROUP on the Microsoft Exchange Information Store. Storage Group - Initialization of Jet failed.

This issue may occur when either of the following conditions are true:

• The streaming file (.stm) that is associated with the database has been deleted.
• Exchange cannot access the streaming file (.stm) that is associated with the database because the permissions for the file have been modified.

The file may be deleted or the permissions may be modified when your antivirus program scans your Exchange 2003 folders.

To resolve this issue, restore the streaming file from the backup copy of the database. You can also verify if the antivirus software moved the streaming file to the Quarantine folder. If the file is in the Quarantine folder, move it to the original location, and then configure the antivirus program so that it does not scan the Exchange 2003 folders.

Note Some antivirus programs change the file properties to Read-only when the files are moved to the Quarantine folder. If you find the streaming file in the Quarantine folder, right-click the file, and then click Properties. Click to clear the Read-only check box before you try to mount the database.
