This afternoon, our tech started getting an error when trying to image machines. The error is "Unable to connect to preboot server. The product license might have expired" We had been going along nicely with imaging, then this started out of the blue today. I have checked the novell-zenimgweb.conf file to make sure that FORCEHTTP=forced is set correctly, and it is.
I am using the May 2011 imaging update.
