Well,
I'm coming in late to the thread, but is it possible that somehow the
startup script is different than the other boxen? Have you combed
through the S10network script? how about copying one of the "like" boxes
script over and doing a diff on it? I dont' have any idea if this is
could help, but at this point, it can't hurt.
