无法通过SCCM进行PXE引导

我已经在Windows Server 2012上创build了SCCM 2012 R2的全新安装。我在单台机器上为操作系统部署创build了一个任务序列。 当我去PXE启动机器时,我得到以下错误:

Pending Request ID:6 Message From Administrator: Configuration Manager is looking for policy. Contacting Server: 10.3.10.93. PXE Boot aborted. Booting to next device... 

SMSPXE.log的最后SMSPXE.log是从昨天开始的:

 ================= PXE Provider shutdown. ===================== 

日志中最近的错误是:

 InstallBootFilesForImage failed. 0x80004005 Warning: Failed to copy the needed boot binaries from the boot image D:\RemoteInstall\SMSImages\POB00005\boot.POB00005.wim. The operation completed successfully. (Error: 00000000; Source: Windows) Failed adding image D:\RemoteInstall\SMSImages\POB00005\boot.POB00005.wim. Will Retry..

任何帮助或指导将不胜感激。
