How do I create NT Logon Scripts for.....

This is running on an NT4 Server with Service Pack 6. The workstations have anywhere from Win95 on up to XP.

OK...This is what this script needs to do. On login it needs to determine which OS is running, this then determines where the desktop folder is located, and then script creates shortcuts on the desktop.

Could someone please point me in the right direction or get me started? Thank you
