DOCUMENT:Q292520 08-MAY-2002 [winnt] TITLE :Conflicting Access Control List Entries Cause Error Message PRODUCT :Microsoft Windows NT PROD/VER::4.0 OPER/SYS: KEYWORDS:kbWinNT400PreSP7Fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== On a server that is running Windows NT 4.0 Service Pack 6 (SP6), you can add extended Microsoft Windows 2000 file permissions by using the Security Configuration Manager tool from the Service Pack 4 (SP4) CD-ROM. This procedure illustrates the problem: 1. You are running Windows Explorer and viewing a folder's security properties. 2. You add a test user to the list of permissions. 3. For this user, you set a deny flag for writing. 4. In a subfolder under that folder, you add the same user and set the Allow Write flag. 5. You select the Allow Inherited Permissions check box for the folder. 6. You click OK. 7. You try to open the Security dialog box again. 8. You see this error message: Unable to display security information On a Windows 2000-based server, the typical security screen is display as you expect for the same configuration. You can verify this by using Cacls.exe to view the access permissions from a command prompt. The Deny Access setting takes precedence over any other flags, so the Write Access flag has no effect. Any user with the conflicting flags set for the folder will cause the screen not to be displayed. CAUSE ===== Windows checks to determine if both the allow and deny flags are set for the object being checked. If they are, error 1336 ("ERROR_INVALID_ACL") is generated and is returned from the function that sums the flags for an access determination. Any error from this function causes the screen not to be displayed.

The English version of this fix should have the following file attributes or later: Date Time Size File name Platform ------------------------------------------------ 04/20/01 04:12p 84,240 Ntmarta.dll Intel 04/20/01 04:08p 140,048 Ntmarta.dll Alpha NOTE: Because of file dependencies, this hotfix requires Microsoft Windows NT 4.0 Service Pack 6a. WORKAROUND ========== Using Cacls.exe, clear the Allow Write flag on the folder. Avoid using deny flags if possible. This symptom also occurs if you set read deny for the Everyone group because Supervisor is part of the group.
