Ok - so its been awhile since i posted this ... post. I've had some preliminary meetings with interested parties and so far I'm getting much opposition to the move.
The biggest argument is - its worked for us thus far, why change? And... passwords slow production down! (yeah, can you believe that!) or 'No one would ever think of deleting files or try to sabotage the network!' (and i say... pffffT - I've done it! It wasn't on purpose in my earlier days... but i still did it, just like someone else could!).
I keep reiterating that NT4 lacks security, functionality, compatibility, support, and so much more. I just can't get them to agree. I'm getting dizzy with all the circles I'm running here!
Thanks in advance.
