sccm osd使用PXE启动时提示找不到文件

原文地址 http://blog.frode.org/?p=55

感觉SCCM的东西比较不稳定，之前虚机启动没有问题，换到真机就碰钉子，重新启动wds服务又正常了，不知道是WDS有问题还是SCCM有问题，联系到之前有人提到wds用过一次就要重启，感觉wds有问题的可能性更大

SCCM and broken PXE

I recently had an incident where I had to reinstall WSUS on my SCCM server, and in the process my PXE boot stopped working. I would receive the following error when trying to boot from PXE:

PXE-T01: File not found
PXE-E3B: TFTP Error – File Not Found

This is a fairly common problem, and usually removing and reinstalling the PXE service point will resolve the issue. Reinstalling or restarting the WDS service is also a possible solution. I also usually run the PXE.msi install package located in bin\i386 in my ConfigMgr installation folder to properly integrate it with WDS.

In my case I tried all of the above, but to no avail. It turned out the boot files for PXE had disappeared from my RemoteInstall\SMSBoot folder, and all I had to do was to copy the files from RemoteInstall\Boot into their respective folders. After this my machines started booting from PXE.
