Hi,
I have the same problem every time I reboot my sccm server which is also the PXE Service point.
Unable to delete file C:\Windows\TEMP\PXEBootFiles\Windows\Boot\EFI\bootmgfw.efi (0x80070005). Retry after 1 seconds
...
Unable to delete folder C:\Windows\TEMP\PXEBootFiles\ (0x80070091). Retry after 1 seconds
...
Still unable to delete folder C:\Windows\TEMP\PXEBootFiles\ (0x80070091) after 31 retries. Continue without further retry.
When it happens, sometime the WDS service fails to start. I have to start it manually. Then it fills the log with the same error, over and over but after a couple of minutes, it succeeds to start the service although the folder ACL has not change nor was it deleted.
And I can see those lines in the smspxe.log
Warning: Failed to copy the needed boot binaries from the boot image D:\RemoteInstall\SMSImages\SMSPKG\S0100002\boot.S0100002.wim.
Cannot create a file when that file already exists. (Error: 800700B7; Source: Windows))
PXE Provider finished loading.
Every thing works as I it should then. PXE responds to client, it boots images, etc.
I've seen this behavior reported many times on the net. Is it a bug ? I'm on windows server 2008 sp2, sccm 2007 sp2.
What should be the "good" ACLs on that folder ?
Oh, and I tried, removing PSP and WDS many times. Still same issue.....
