I have read through almost all post and fixed all most all my errors. I have two problems now and I think they are related.
First I push a image and the client restarts but does not pick up the pxe and in WDM to will automatically roll to boot. If I turn off the S90 for about 5 minutes it will then pick it up and image the client. I do get one error “Wisard was not detected under server properties, but then it images the client ok.
I just updated to 4.7.1. Option 66 and 67 were configure but I removed it a few weeks ago as all client were hanging up.
