SYMPTOMS
On a Microsoft Windows Server 2003-based computer, consider the following scenario. You run the Chkdsk.exe utility in fix mode. You use the /f switch, the /x switch, or the /r switch with this command. In this scenario, you find that the access control lists (ACLs) on some files may revert to their default values.



CAUSE
This problem occurs because of an exception that occurs when the NTFS file system transaction log is full and when security descriptors are being updated. In this scenario, the security descriptors can be left in an incorrect state. If you then run Chkdsk again, this will cause the security descriptor entries to be reset to their default value of Full Control for the Administrators group and Full Control for the SYSTEM user account.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section. This problem was first corrected in Windows Server 2003 Service Pack 2.



MORE INFORMATION
The problem occurs because under certain circumstances the Chkdsk.exe utility incorrectly identifies security descriptors as corrupted and therefore resets them to the default value. Entries that resemble the following appear in the Chkdsk.exe utility log: CHKDSK is verifying security descriptors (stage 3 of 3)... Repairing the security file record segment. Deleting an index entry with Id 8447 from index $SII of file 9. Deleting an index entry with Id 31126 from index $SII of file 9. Deleting an index entry with Id 50636 from index $SII of file 9. Deleting an index entry with Id 31126 from index $SDH of file 9. Deleting an index entry with Id 50636 from index $SDH of file 9. Deleting an index entry with Id 8447 from index $SDH of file 9. Replacing invalid security id with default security id for file 1461234. Security descriptor verification completed. Windows found problems with the file system. Notes
 * This hotfix prevents future corruption. It does not fix existing corruption. Contact Microsoft Product Support Services (PSS) to help troubleshoot existing corruption.
 * The number of reported errors and the security IDs may vary. The index entry IDs and the file numbers may also vary. This problem may occur on large volumes with as many as 4,194,303 or more files.
