Hmmm ... Your citing this reminds me of reading something about this in the MSDN docs during my roamings to try to understand it. Thanks for pointing this out. I'll have to see what I need to do to convert the C code to VFP. Thanks again Ed.

Enabling and Disabling Privileges
>The following example shows how to enable or disable a privilege in an access token. The example calls the LookupPrivilegeValue function to get the LUID that the local system uses to identify the privilege. Then the example calls the AdjustTokenPrivileges function, which either enables or disables the privilege that depends on the value of the bEnablePrivilege parameter.
