Network Assistant 4.0.x: Workstations Stop Responding ("Freeze") While Restarting

Deselecting Voice Verification resolves an issue in which Network Assistant 4 workstations may stop responding ("freeze") when restarted.
Symptom

A Network Assistant 4 client or clients stops responding when restarted. The monitor's screen image goes blank (dark, or black) as if restarting, but the power light indicates the computer is still on.


Solution

Deselect the Voice Verification option in the Multiple Users control panel of the client computer(s).

Macintosh Manager clients must log out, or a nonmodal dialog box appears, preventing the computer from restarting.
