Three changes that go together so a re-image never hits "System error 53":
1. dnsmasq dhcp-script hook (playbook/pxe-server-helpers/pxe-dhcp-hook.sh)
Fires on every add/del lease event. Runs conntrack -D and ss -K for the
client IP so any stale ESTABLISHED SMB session from a previous boot is
cleared before the client reconnects. Runs as root (dnsmasq default).
Wired into /etc/dnsmasq.conf via dhcp-script= directive in the playbook.
2. One-source PPKG (playbook/startnet.cmd + startnet-template.cmd)
The 5 per-Office PPKG copies were bit-for-bit identical; only the
filename differs because BPRT parses Office and Region out of the name.
Store one source file (e.g. GCCH_Prod_SFLD_v4.11.ppkg) and construct
the BPRT-tagged target filename at menu-selection time from variables:
SOURCE_PPKG / PPKG_VER / PPKG_EXP / REGION / OFFICE
copy /Y "Y:\ppkgs\%SOURCE_PPKG%" "W:\Enrollment\%PPKG%"
Bumped PPKG_VER v4.10 -> v4.11 and PPKG_EXP 20260430 -> 20270430.
Saves ~30G on disk per version.
3. run-enrollment.ps1 already committed in 5a9c3db uses provtool.exe
directly (no PowerShell cmdlet 180s timeout). Included here because it
is part of the same end-to-end PPKG path.

# pxe-dhcp-hook.sh - dnsmasq dhcp-script hook.

# Runs every time a PXE client gets/changes/releases a DHCP lease on
|
|
# 10.9.100.0/24. Flushes conntrack entries and drops any lingering
|
|
# TCP sockets for that client IP. Prevents stale server-side state from
|
|
# causing "System error 53 - network path not found" when a WinPE client
|
|
# re-images the same machine without a clean SMB session teardown.
|

#

# dnsmasq calls this with argv:
|
|
# $1 = action (add | old | del)
|
|
# $2 = mac address
|
|
# $3 = client IP
|
|
# $4 = hostname (may be empty)
|
|
#
|
|
# Must exit quickly; dnsmasq waits for it. Logs to syslog via logger.
