After IE 5.5 and with the IEAK, URD and "flat" media, the clients can
install IE without administrator privileges. But I agree with you that
the logon installation will be disruptive and costly. Simple math:
300 clients x 1 hr each (?) x $50/hr (?) = $15,000.
I would think that to be a conservative estimate (unless this is a call
centre somewhere where people are paid $4.00/day, and then maybe $15,000
for a big outfit is like $1.50 to me!). It doesn't take into
considerations how many machines might get hiccups and how many might
reboot to blank desktops. I would second your motion of trying another
installation/deployment method.
