This problem only happens with Apple IIGS computers that have ROM 01. There are two solutions:
1) Upgrade to ROM 03. It doesn't have a problem booting from an AppleShare
server.
2) Create an AppleShare boot disk and start the Apple IIGS from that disk.
This allows you to use the Auto Logon feature to set the boot disk to automatically log into the server and launch a program at startup.
