Does UNIX-Chmod in windows exist?

Is there an command in windows to chmod a file to 666 so that when I mount a NAS on solaris, the user can read/write/remove the file from unix server?

Traditionally, we invoke ftp from unix to windows, get the file and remove it. With a NAS, can windows chmod the file 666 so that unix can edit the file?

Reason for such needs
-----------------------
I am facing some difficulty with the new NAS purchased. Out NT admin don't know how to auto-mount the NAS mapped drive when the NT server reboot (unlike DAS which doesn't have such problem). So I am looking for work-around.

Tks.

There is no 666 per se in Windows, but have you tried giving the file the following attributes? Read, Write, Execute? Your NT Admins should know how to do this..

I did but the windows permission is not seen in UNIX.
I supposed the windows attrib command is totally different from UNIX chmod.
