ID: Q250318

The information in this article applies to:

Microsoft Windows NT Server versions 4.0, 4.0 SP1, 4.0 SP2, 4.0 SP3, 4.0 SP4, 4.0 SP5, 4.0 SP6, 4.0 SP6a
Microsoft Windows NT Workstation versions 4.0, 4.0 SP1, 4.0 SP2, 4.0 SP3, 4.0 SP4, 4.0 SP5, 4.0 SP6, 4.0 SP6a

SYMPTOMS

Windows NT Explorer may generate a "The parameter is incorrect" error message when you attempt to view permissions on a folder after you use Cacls.exe with the /G switch to edit permissions.

CAUSE

The Windows NT Explorer Access Control List (ACL) editor generates an error message if any generic permissions, such as GENERIC_READ, GENERIC_WRITE, or GENERIC_EXECUTE are also present when the GENERIC_ALL permission is set.

RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Windows NT 4.0 service pack that contains this fix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information on support costs, please go to the following address on the World Wide Web:

The English-language version of this fix should have the following file attributes or later:


   Date         Time     Size      File name    Platform
   -----------------------------------------------------
   01/04/2000   07:47p   419,088   Netui1.dll   Alpha
   01/04/2000   07:55p   226,064   Netui1.dll   I386

WORKAROUND

To work around this problem, use the /P switch in place of the /G switch. This replaces the permissions, but removes any inherited permissions.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

If you are setting GENERIC_ALL access, the Windows NT Explorer ACL editor should determine whether GENERIC_READ, GENERIC_WRITE, or GENERIC_EXECUTE permissions are already present, and if so, turn off those bits.
