Managing users on NT

I work in a school where users/groups
change frequently. is there a software
package that will allow creating
user/group/login script/create directory
and assign privledges under one roof? I
am using the NT (4) resource kit and
cobbleingtogether many .bat files.
starting witha a tab delimited text file. I am
finishing with "Quota Advisor" for directory
size control. My desktops are W95/98.
