Active Directory Services

Hi all..
I have used ADSI a bit.. I am able to create users, groups.. and much more.. now wondering how to get Folder Sharing Permissions set for each user... I am creating a user.. assigning him to a group.. I am creating a directory for this user and i want to create a share with permissions to only that user....Any idea??

One another question...
Is there any way (API or non API) to get the Install location of WinNT(or 2000) of a remote computer???

This is urgent plz....

I expected 1000 replies when came back it today after 2 days...BUT :(
Hey C'Mon.. there must be someone who knows this thing....
