On a Windows 2000 server running Microsoft Exchange 2000. The public and private Mailbox stores won't mount. This was initially caused by a full hard drive, however even after freeing up plenty of space, the mailbox stores refuse to mount.
No relevant errors are logged to the application or server event logs.
When I try to mount the stores from the exchange system manager I get the well documented c1041724 error. I have gone through all the troubleshooting documents related to this error with no success.
I did discover that somehow the security settings for the mailbox stores weren't correct. As noted in http://support.microsoft.com/?kbid=827283
the exchange domain servers group did not have full control of the mailbox stores. I corrected this problem but there was no change to the larger symptoms.
I checked the states of both stores and found them to be in "clean shutdown" state.
My only thought is that this is the first time we've had to restart the exchange server since the DST updates were done before the actual DST switch. Could something have gone haywire after the 11th of march?
