Hold on gentlemen!
There's a command line utility in NT by which you can display and modify NTFS permissions on files and folders. It's called "CACLS.EXE". It displays or modifies access control lists (ACLs) of files on NTFS partitions.
CACLS filename [/T] [/E] [/C] [/G user

erm] [/R user [...]]
[/P user

erm [...]] [/D user [...]]
filename Displays ACLs.
/T Changes ACLs of specified files in
the current directory and all subdirectories.
/E Edit ACL instead of replacing it.
/C Continue on access denied errors.
/G user

erm Grant specified user access rights.
Perm can be: R Read
C Change (write)
F Full control
/R user Revoke specified user's access rights (only valid with /E).
/P user

erm Replace specified user's access rights.
Perm can be: N None
R Read
C Change (write)
F Full control
/D user Deny specified user access.
Wildcards can be used to specify more than one file in a command. You can also specify more than one user in a command.
Nishet, I hope "CACLS.EXE" will let you do what you want.
