XADM: Information Store Fails To Start With -1011 Error

• Microsoft Exchange Server, versions 4.0, 5.0, 5.5

SYMPTOMS

If a copy of the Microsoft Exchange Server information store (the Pub.edb and Priv.edb files) is restored from an offline backup when the service is Restarted, it will fail with a -1011 error. The -1011 error produces an entry in the Windows NT Event Viewer Application Log with Source ID 2048. The error message will read as follows:

The Information Store was restored from an off-line backup. Run ISINTEG -PATCH before restarting the Information Store.

CAUSE

This error occurs because the Globally Unique Identifiers (GUIDs) used by the restored information store are old, and matching GUIDs may already exist. The GUIDs for this restored information store need to be replaced to ensure that they are unique.

RESOLUTION

This is by design. You need to patch the information store to replace the GUIDs used by the restored information store by running Isinteg - patch. Isinteg in patch mode will run against the entire Information Store (both the Pub.edb and Priv.edb files). It will generate new GUIDs and also patch replication information to prevent incorrect backfilling.

To run Isinteg -patch:

1. Ensure that the Directory and System Attendant Services are running. If either of these services are not running, Isinteg will fail with a DS_COMMUNICATIONS_ERROR message.



2. Change to the Exchsrvr\Bin directory, and type Isinteg -patch. The GUIDs will be replaced, and Isinteg will report that the Information Store has been updated successfully.



3. Restart the Information Store service.

MORE INFORMATION

The Windows NT Backup utility will automatically patch the Information Store when it is restored from an online backup only. If the Information Store is restored from an offline Windows NT Backup, you must run Isinteg.exe.

Isinteg.exe run in patch mode performs no integrity checks, so you should run Isinteg.exe in test mode after running it in patch mode. For instructions on how to run Isinteg.exe in check mode, please see pages 617 and 618 of the Microsoft Exchange Administrator's Guide.
