TITLE   :XADM: Error -1201 Occurs When Starting the Information Store
PRODUCT :Microsoft Exchange
PROD/VER:winnt:4.0,5.0,5.5
OPER/SYS:
KEYWORDS:exc4 exc5 exc55

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Exchange Server, versions 4.0, 5.0, 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you try to start the Microsoft Exchange Server Information Store service,
the service does not start and reports a server-specific error 4294966095. The
Windows NT Event Viewer indicates that the service returned an error -1201.

CAUSE
=====

Error -1201 commonly occurs because of minor inconsistencies or corruption in
the Priv.edb or Pub.edb files.

It can also occur when the *.edb files are on drive C, the *.log files are on
drive D, and there is some sort of unrecoverable hardware failure on drive D. At
that point, you are in the situation described above because the store will be
inconsistent and the log files are not available.

WORKAROUND
==========

The recommended approach to resolving this problem is to restore the information
store from the latest backup.

If a recent backup is not available, or if restoring the backup will result in
data loss (circular logging is enabled) follow these steps:

1. Back up the entire Mdbdata folder.

2. Make sure you have sufficient free disk space:

   Exchange Server 4.0 and 5.0
   ---------------------------

   You need 110 percent of the larger of Priv.edb and Pub.edb files in free disk
   space.

   Exchange Server 5.5
   -------------------

   You need 25 percent of the larger of Priv.edb and Pub.edb files in free disk
   space.

3. Run the following commands from a Windows NT command prompt:

   Exchange Server 4.0 and 5.0
   ---------------------------

   edbutil /d /r /ispriv /tx:\tempdfg.edb
   edbutil /d /r /ispub /tx:\tempdfg.edb
   isinteg -fix -pri
   isinteg -fix -pub

   Exchange Server 5.5
   -------------------

   eseutil /p /ispriv /tx:\tempdfg.edb
   eseutil /p /ispub /tx:\tempdfg.edb
   isinteg -fix -pri -test alltests
   isinteg -fix -pub -test alltests

   where x: is the drive containing the required free disk space.

   NOTE: When the Information Store service has started, after the repair
   process, make a full online backup immediately.

MORE INFORMATION

Error -1201 refers to the Jet error: JET_errDatabaseDuplicate
