If you are re-installing a workstation you have to clear the PXE log on the machine account on CM console to make the PXE work properly. If you are installing a new machine the easiest way is to deploy the OSD task to All Unknown Computers collection. But just to make safer remember to deploy the task sequence in Available mode. rgds H.Nakari Peters adwise is propably the best to start with. You didn't mention if the WDS/PXE has been working earlier? Check the log in question and eventually get back with a little more information about the issue.
