TITLE   :XADM: How to Complete Edbutil Terminated with Error -1808
PRODUCT :Microsoft Exchange
PROD/VER:Windows:4.0,5.0
OPER/SYS:
KEYWORDS:

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

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

CAUTION: This article contains information about the Microsoft Exchange
database utility (edbutil /d /r). Using it incorrectly can cause problems.
Before you run this utility, you should first make a backup copy of the
database files. Microsoft cannot guarantee that problems resulting from the
use of the utility can be solved. Use this tool at your own risk.

SYMPTOMS
========

When you run the command line utility Edbutil with the defragmentation option
(/d) and the repair option (/r) on the private information store, it might fail
to complete and you receive one of the following errors:

   Edbutil terminated with error -1808

   -or-

   Error -1808 (0xfffff8f0) JET_errDiskFull 4294965488

The following event is written in the event viewer:

   Event ID: 1005
   Source: MSExchangeSA
   Category: Monitoring
   Description: Unexpected error <<0xc0040000 - The Microsoft Exchange
   Server computer is not available. Either there are network problems or
   the Microsoft Exchange Server computer is down for maintenance.
   Microsoft Exchange Server Information Store ID no:
   8004011d-0524-00000000>> occurred.

When you check the amount of free disk space on the drive that hosts the Exchange
Bin directory (on drive C, for example), you may find only a few megabytes of
disk space available. The drive that hosts the Exchange databases (drive D, for
example) may have plenty of free disk space.

WORKAROUND
==========

The following steps explain how to complete Edbutil /d /r in this case:

1. Check the size of the C:\Exchsrvr\Bin\Tempdfrag.edb file. You will find that
   its size is smaller than the size of the Priv.edb file. Delete the
   C:\Exchsrvr\Bin\Tempdfrag.edb file.

2. If the free disk space on drive D is only slightly greater than 1.2 times the
   size of the Priv.edb file, create a new directory D:\Exchsrvr\Bin and copy
   the Edbutil.exe and Edb.dll files from C:\Exchsrvr\Bin to the new directory.

   -or-

   If the free disk space on drive D is greater than 1.2 times the size of
   Priv.edb file by more than 38 MB, copy the C:\Exchsrvr\Bin directory to
   D:\Exchsrvr\.

   -or-

   If the free disk space on drive D is less than 1.2 times the size of the
   Priv.edb file, refer to the MORE INFORMATION section of this article.

3. Run the following command:

   d:\exchsrvr\bin\edbutil /d /r /ispriv

   It should start creating the temp file Tempdfrag.edb on D:\Exchsrvr\Bin, and
   should complete successfully if the only problem was insufficient disk space.

4. After Edbutil completes successfully you can delete the D:\Exchsrvr\Bin
   directory to free the 37.4 MB of disk space.

MORE INFORMATION
================


Information about the options that you can use with the Edbutil command line
utility is available. For additional information about this utility, please see
the following article in the Microsoft Knowledge Base:

   Q143233 XADM: Command-Line Parameters for Edbutil.exe

If the information store fails to start because there is insufficient disk space
(which might produce the same error ID -1808), you can attempt to reclaim disk
space. For additional information about using Windows NT Performance Monitor to
track disk space and reclaim it, please see the following article in the
Microsoft Knowledge Base:
