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 described in this article and should be applied only to systems 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 on support costs, please go to the following address on the World Wide Web: http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS NOTE: In special cases, charges that are normally incurred for support calls may be canceled, if a Microsoft Support Professional determines that a specific update will resolve your problem.

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 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.
