This is a consistent problem with 1 eMac out of 5 identical machines.
They all connect to our college WIndows-based LAN using Airport / IPsec. Our Xserve does not run DNS / DHCP / VPN etc. just AFP and Open Directory for the OS X users. 4 machines log users in with their homes fine, 1 displays question marks regularly, even though IPSec is fine and I can ping the Xserve and other ethernet clients
these 5 eMacs are in the same location, so it’s unlikely to be intereference
can anyone suggest things to look for ? logs to check or reports I can run via Terminal ?
many thanks
