The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine whether the default administrative shares have been disabled:
If the Exchange Server Analyzer finds that the value for AutoShareServer is set to 0, an error is displayed.
This error indicates that the default server-created administrative shares have been disabled on this server. An online backup or restoration of Exchange Server may not work when the default administrative shares have been disabled. Depending on the backup program, you may receive the error messages when trying to restore data. You may also see error messages in the tape backup log.
Additionally, when the administrative shares have been removed, you may receive the following message during an online backup of Exchange Server: Unexpected error 0xc0040000 the Microsoft Exchange Server computer is not available. To resolve this problem, it is recommended that the default administrative shares be re-enabled by editing the registry and restarting the Server service.
