Im sure this has been p[osted before but I cant find any answers.....

I'm trying to do an audit of old users. The info I'm after is a) Last
login before 2005 b) All disabled accounts and c) The space each one
takes up (not just in the home directory). We have around 5,000 users
so I'd like it to be able to do all OU's from [root].../s or something.
Anyone know the best way? I've tried DSRazor which would be the bets I
think but as yet we havent purchased it and the evaluation is limited
to 3 results. Also tried DSReport but that has to be run on each OU
(plus it doesnt filter out the years) and finally tried Import/Export
from NWAdmin but...we're on Outlook....(dont ask why). Any
