<p>Just to add to this:, After a rebuild to rc1 now everyting seemed ok at first, added a task sequence and had the thing booting from PXE but as above rebooted my server and have the wds service stuck at "Starting".</p>
<ul>
<li>I added the regkey from the above comment for <em>NumberOfThreads</em> this is a sccm 2007 fix but I'll try it. Also note here had no PXE key under SMS to start with. tried 32 bit Dword no resolution for me after reboot.</li>
<li>Then I did as we are told, remove DP, WDS role, reboot and added DP back with PXE, rebooted it worked once, then after another reboot it's back to "starting"</li>
<li>Tried delayed start, same result, going to try a complete rebuild of the vm , (this machine had the beta on previously)and start again, if it still occurs post more.</li>
</ul>
