Hi Mike,
Thanks for your update!
Regarding to the disk defragmenter analyze report, it is normal. Yes, you
are right. We need use the exeutil tool to reduce the Exchange database
size. You can refer to the following KB articles for detail steps:
328804 How to Defragment Exchange Databases
http://support.microsoft.com/?id=328804
192185 XADM: How to Defragment with the Eseutil Utility (Eseutil.exe)
http://support.microsoft.com/?id=192185
If you have any further question on the issue please let me know. I am
happy to be assistance of you and look forward to your update!
Have a nice day!
Sincerely,
Jenny Wu

>> c). It cannot defragment one volume while scanning another.
>> d). It cannot be scheduled.

>> f). It cannot defragment NTFS volumes with cluster sizes larger then 4

>> Defragmenter in Microsoft Windows XP and Microsoft Windows Server 2003.

the

Disk

>> http://support.microsoft.com/default.aspx?scid=kb;en-us;227463

>> http://support.microsoft.com/default.aspx?scid=kb;en-us;130539

>> III. It is recommended that you use the "Eseutil /d" command to defrag
the
>> Exchange 2003 server databases. When the users delete messages, the size
of
>> the database will keep the same and you must perform an offline
>> defragmentation using the exeutil tool to reduce the Exchange database

space
>> equal to 110 percent of the size of the database that you want to
process
>> so if you do not have enough free space to run the eseutil tool, you can
>> defrag the database on another computer. See:

>>
>> 192185 XADM: How to Defragment with the Eseutil Utility (Eseutil.exe)

>> IV. What is more, you can use the Disk Cleanup tool to delete all
temporary

>> System Tools -> Disk Cleanup. For more information, you can refer to the

>>
>> 310312 Description of the Disk Cleanup Tool in Windows XP
>> http://support.microsoft.com/?id=310312
>>
>> V. Perform an online backup of the Exchange 2003 Information Store to
purge

>> NTBackup tool or an Exchange-aware third party backup tool. To use
NTBackup
>> to backup Exchange information store, you can refer to the following
>> Microsoft KB article:
>>
>> 258243 How to Back Up and Restore an Exchange Computer by Using the
Windows
>> http://support.microsoft.com/?id=258243
>>
>> VI. I would like to give your some information about some Best Practices
>> experience for defragment:
>>
>> - Analyzing after large numbers of files are added
>>
>> Volumes might become excessively fragmented when users add a large
number
>> of files or folders, so be sure to analyze volumes after this happens.
>> Generally, volumes on busy file servers should be defragmented more
often
>> than those on single-user workstations.
>>
>> - Ensure that your disk has at least 15% free space
>>
>> A volume must have at least 15% free space for Disk Defragmenter to
>> completely and adequately defragment it. Disk Defragmenter uses this
space
>> as a sorting area for file fragments. If a volume has less than 15% free
>> space, Disk Defragmenter will only partially defragment it. To increase
the
>> free space on a volume, delete unneeded files or move them to another
disk.
>>
>> - Defragmenting during low-usage periods
>>
>> Defragment file server volumes during low-volume usage periods to
minimize
>> the effect that the defragmentation process has on file server
performance.
>> The time that Disk Defragmenter takes to defragment a volume depends on
>> several factors, including the size of the volume, the number of files
on
>> the volume, the number of fragmented files, and available system
resources.
>>
>> - Defragmenting after installing software or installing Windows
>>
>> Defragment volumes after installing software or after performing an
upgrade
>> or clean install of Windows. Volumes often become fragmented after
>> installing software, so running Disk Defragmenter helps to ensure the
best
>> file system performance.
>>
>> Hope above information helps! I am happy to be assistance of you and
look
>> forward to your reply!
