CAUSE
This error occurs because a directory store database is restored which contains a service account with an incorrect security ID (SID). This may happen if the Windows NT Security Account Manager (SAM) database has been lost or re-created. The Exchange Server directory service will start, but after starting the information store service, the error message displays.

obviously that is what happened when nt was reinstalled- sid has been changed


WORKAROUND
The directory service can be regenerated using the restored version of the information store databases.
Reinstall Exchange Server with the new service account and restore only the information store databases.
Run the Isinteg -patch command to synchronize the GUIDs between the information store and directory service databases.
Start the Exchange Server directory service.
In the Exchange Server Administrator program, choose the Exchange Server computer's Server Properties page.
On the Advanced tab, under DS/IS consistency adjustment, select All inconsistencies, and then click Adjust.

NOTE: In Exchange 5.5, select the Synchronize with the directory check box, and then create new directory entries for mailboxes that do not have a corresponding directory entry.
Your directory should be repopulated and contain a service account with a proper SID.

If a .CSV file with exported directory information is available, that information can be imported into the Microsoft Exchange Server directory

cheers
