Hi guys,
Finally got some time to look into it.
Long story short, this smells like infrastructure problem.
SARR passes over 546/547 port pair. That is between UEFI PXE client and
DHCP server (even if it is the same machine).
The next packet is essentially a Boot Server choice step. UEFI PXE
client sends a unicast discovery packet towards Boot server (same
machine, same address) coded as DHCP Request.
The release packet is a direct reaction to 3 second timeout (see time
diff between packet 9 and 11).
See section 2.2.1 in PXE spec:
http://www.pix.net/software/pxeboot/archive/pxespec.pdf
Please verify that your WDS service is running correctly, since clearly
there is no reaction to that packet from Boot server.

Any inputs?
We kind of blocked on this for a week. Kindly look into packet capture
and suggest a path forward.

Looking at it. Any chance to get Wireshark trace for this scenario?
