Pushing Drive mapping via AD

Hi all

I have a NAS used as a common storage. I want to push drive mapping to all users within the AD group (not home directory but a common folder). I don’t have OU’s within my structure yet.

What’s the easiest way to do it.
For example: I have maps like:
net use * \\abcfiler\Accounts
net use * \\abcfiler\Marketing

I have User Groups defined as Accounts and Marketing having Full Control over their respective shares and there are over 20 other groups.

The aim is to write a script, of something of this sort:
If member of ‘accounts’, map “net use * \\abcfiler\Accounts”
If member of ‘marktg;, map “net use * \\abcfiler\Marketing”
.
.
etc.
And, where within my Windows 2003 AD, should I place this?

Pls advise!!
