Why do I receive a file-copy error when I perform an in-place upgrade of Windows Server 2003?

Start a command session.

Run Esentutl's repair option by typing

esentutl /p %windir%securitydatabasesecedit.sdb 

Click OK to the displayed dialog box. Esentutl will confirm the repair by displaying a log file similar to the following example:

Microsoft(R) Windows(R) Database UtilitiesVersion 5.2Copyright (C) Microsoft Corporation. All Rights Reserved.Initiating REPAIR mode...Database: C:WINDOWSsecuritydatabasesecedit.sdbTemp. Database: TEMPREPAIR4072.EDBChecking database integrity.Scanning Status (% complete)0 10 20 30 40 50 60 70 80 90 100|----|----|----|----|----|----|----|----|----|----|...................................................Integrity check successful.Note:It is recommended that you immediately perform a full backupof this database. If you restore a backup made before therepair, the database will be rolled back to the stateit was in at the time of that backup.Operation completed successfully in 129.176 seconds. 

Navigate to the %windir%security folder by typing

cd %windir%security 

Remove the edb0000x.log file by typing

del edb0000*.log 

You'll then be able to perform the in-place upgrade.
