I had exactly the same issue as Cybertronic, when installing XP Pro (SP2) using nLite 1.3.5 for the first time this morning (have used previous versions many times without encountering this issue before), i.e. the absence of autoplay, the shell hardware service not running, and the same 1083 error msg in event viewer when trying to start that service. I determined that it was caused by an svchost error. The Shell Hardware Detection Service is configured to run under netsvs - but it was incorrectly listed in the relevant reg key. If you go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SvcHost then double-click on 'netsvcs', the relevant service name (ShellHWDetection) should be included in the list of services. In mine, 'ShellHWDetection' appeared at the end of the list, with a blank space between it and the other items. Odd. So anyway, by removing the blank gap, and inserting the name in it's proper place in the list, upon restarting Windows, Shell Hardware Detection service was running properly, the DVD drive was now recognised, and autoplay function was back! Haven't worked out yet what caused this to happen on this occasion, but hopefully this fix might help anyone who encounters the same problem...
