Recently when I enabled PXE support for clients on a SCCM 2012 Distribution Point I received the following error in the SMSPXE.log located in C:\Program Files\SMS_CCM\Logs
failed to copy C:\RemoteInstall\SMSTempBootFiles\BAM00001\WINDOWS\Boot\PXE\pxeboot.com to C:\RemoteInstall\SMSBoot\x86\pxeboot.com
InstallBootFilesForImage failed. 0x80070003
Warning: Failed to copy the needed boot binaries from the boot image C:\RemoteInstall\SMSImages\BAM00001\boot.BAM00001.wim.
The operation completed successfully. (Error: 00000000; Source: Windows)
Failed adding image C:\RemoteInstall\SMSImages\BAM00001\boot.BAM00001.wim. Will Retry..
The system cannot find the path specified. (Error: 80070003; Source: Windows)
I found that C:\RemoteInstall\SMSBoot\x64 and C:\RemoteInstall\SMSBoot\x86 were also empty.
Looking further into the log I could see that the boot images were been mounted and closed without doing anything.
The solution for me was to mount and unmount the images and then restart the WDS service. Everything worked like a charm. It must be a bug with the intial deployment
