There's not enough information here.

Can they get in at all? What about pinging it? Can they get in after
bootup, and then not later? What does ifconfig say? What about netstat -r?

As far as the monitor issue, I observe the same problem on my IIci running
1.4.2 -- if I boot it headless and later plug in a monitor, the console
no longer responds. Something for the usual suspects to look at, I guess.
