Hi
we have just set up SCCM 2012 and have configured OSD. It works well apart form the length of time it takes to download the boot.wim on a PXE boot.
We took some network traces and noticed that TFTP was behaving as if the Windowing was set to 1 so every block was being ACK'ed before another was sent.
I checked the Windowing size on the bcd file of the boot image and the setting was
ramdisktftpwindowsize 4
Any ideas why TFTP doesn;t seem to be picking this up?
