Suddenly we are unable to image Dell workstations. Workstations vary, but for the most part are gx 745's. The computer's pxe boot and we get the zenworks menu. Choosing any option (usually maint. mode) causes the computer to load the zenworks splash screen, this stays up a while and then you get a redscreen asking for a manual setup that it cant load zenworks files. Switches are Cisco 2950's with gig backbones. I think that the nic drivers arent loading or something is timing out. Not sure where to look for logfiles.
