Description: The Group Policy client-side extension Security was passed flags (17) and returned a failure status code of (1332).
To find the problem:
1. I navigated to HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon\GPExtension\{827...} and
Added Value name ExtensionDebugLevel as a type REG_DWORD, setting it to 2. This turned on
logging for Winlogon.
2. At a CMD prompt, I typed:
secedit /refreshpolicy machine_policy /enforce to create
%SystemRoot%\Security\logs\Winlogon.log.
3. After inspecting Winlogon.log, I discovered that someone at Microsoft failed to learn the basics of database design,
and did not implement referential integrity.
I had recently uninstalled IIS on my Windows 2000 Server. The initial install created the IUSR_... and
IWAM_... accounts and assigned users rights. The uninstall removed these accounts,
but failed to remove them from User Rights Assignment.
The fix was to manually remove the accounts from the from User Rights Assignment at
Administrative Tools / Local Security Policy / Local Policies.
