Hello ActiveDir, I know this is out of topic, but it I think this is a non common issue to know about.
I just came across a bug on ntfs.sys. It made chkdsk reporting many errors on security descriptors like this: ---- Replacing invalid security id with default security id for file 1396371. Replacing invalid security id with default security id for file 1396372. Replacing invalid security id with default security id for file 1429033. Fixing mirror copy of the security descriptors data stream. Security descriptor verification completed. Windows found problems with the file system. Run CHKDSK with the /F (fix) option to correct these. ---- At the beginning I just thought about data corruption. I just opened a call to pss to get the good way to handle it (it's on a MSCS cluster). In fact, this is a ntfs.sys bug, that should raise with 4 Millions of File or an MFT of 4GB. We have 1,6 Millions of files. original: http://support.microsoft.com/default.aspx?scid=kb;EN-US;913034 The Chkdsk.exe utility incorrectly identifies and resets security descriptors in Windows Server 2003 New one: http://support.microsoft.com/default.aspx?scid=kb;en-us;915691 FIX: The system stops responding during high disk activity on a computer that is running Windows Server 2003 the last version of ntfs.sys is 5.2.3790.2655 MS gave us an internal tool get trough this SD issue.
