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 is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem.

To resolve this problem, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

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 that this is a problem in the Microsoft products that are 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.
