SubInAcl error with /cleandeletedsidsfrom option

Hi,

I'm using Windows XP Pro. SP2. I wish to get rid an unknown account
(displayed in the Security tab of multiple folders and files) which is an old
account that I just deleted. This account is on my own machine (no domain).
Before messing up my system with the SubInAcl.exe, I tried to remove the
unknown account from a single file with the following syntax:

subinacl /file c:\setup.log /cleandeletedsidsfrom

This command returns the following error message:

WARNING : /cleandeletedsidsfrom : Invalid option : c:\setup.log

I also tried the following command:

subinacl /subdirectory c:\temp\*.* /cleandeletedsidsfrom

But I still receive the following error message:

WARNING : /cleandeletedsidsfrom : Invalid option : c:\temp\*.*

Any idea of what is wrong with my command-line?

- Thanks.
