GE-Enforce mounts the SFLD share on W: and holds it for the whole enforce
cycle, passing W:\<pctype> as -InstallerRoot to Install-FromManifest. Two
scripts that run inside that cycle, as SYSTEM in the same drive namespace,
mapped W: for their own use and deleted it on exit:
Restore-UDCData.ps1 manifest PS1 entry, mounts the UDC backup share
Update-MachineNumber.ps1 "Apply Machine Number" task, same backup share
Once W: is gone, the next manifest entry's Join-Path resolves against a dead
drive qualifier. In Windows PowerShell 5.1 that emits nothing rather than
throwing, so the null lands in Test-Path -LiteralPath and the entry dies with
"Cannot bind argument to parameter 'LiteralPath' because it is null".
Observed on a collections bay: the controller-credential entry, which runs
immediately after UDC Data Restore, failed this way while the entry one line
earlier had resolved a W: path successfully one second before.
Restore-UDCData now uses R: and Update-MachineNumber uses N: for the UDC
backup share. Neither letter is referenced anywhere else in the tree; V: was
not an option because Restore-EDncReg and Update-MachineNumber's NTLARS
restore already use it.
The re-mount at GE-Enforce.ps1:239-244 does not cover this. It runs after the
manifest loop and blames idle SMB timeout, but the whole cycle took one
second, so timeout was never the cause.
OLD design: a single 'Check Machine Number' scheduled task ran as the
logged-in user (BUILTIN\Users, Limited) on AtLogOn. It both showed the
InputBox AND tried to update HKLM\SOFTWARE\WOW6432Node\GE Aircraft
Engines\DNC\General + C:\ProgramData\UDC\udc_settings.json. To make
those non-admin writes possible, 02-MachineNumberACLs.ps1 pre-granted
BUILTIN\Users SetValue + Modify on those targets during imaging.
Three problems with that:
1. SECURITY: any logged-in user could overwrite the machine-identity
reg key.
2. FRAGILE: ACL grants raced with eDNC install timing on some bays
(eDNC reg key didn't exist yet when 02-MachineNumberACLs ran;
OpenSubKey returned null, ACL silently skipped, Check-MachineNumber
later failed with PermissionDenied).
3. SILENT-SUCCESS BUG: Update-MachineNumber's Set-ItemProperty calls
lacked -ErrorAction Stop. PermissionDenied is a non-terminating
error in PS5.1, so the try/catch never fired. The script set
$out.EdncUpdated=$true anyway and the dialog reported success
while the reg value stayed at 9999. WJF capture log on FGY07FZ3
shows this exact pattern.
NEW design - two scheduled tasks split by responsibility:
- "Prompt Machine Number" : AtLogOn trigger, BUILTIN\Users (Limited).
Reads current values (read-only). If 9999, shows InputBox. Writes
typed number to C:\Logs\SFLD\machine-number-request.txt. Triggers
SYSTEM Apply via schtasks /run. Polls for result JSON (60s timeout).
Shows result MessageBox with TopMost so it isn't hidden behind
other windows.
- "Apply Machine Number" : on-demand, SYSTEM (Highest). Reads the
request file, calls Update-MachineNumber (full HKLM + ProgramData
access from SYSTEM context). Pulls per-machine NTLARS .reg + UDC
settings JSON + UDC live data from the SFLD share if site-config
has share paths. Writes result JSON. Removes request file.
Unregisters the Prompt task on full success (Prompt itself can't
self-unregister - Limited users can't delete a SYSTEM-owned task).
- Default task SDDL only allows Admins + SYSTEM to read/run a
SYSTEM-owned task. Added BUILTIN\Users GR+GX ACE via COM
SetSecurityDescriptor so the Limited Prompt task can schtasks /run
Apply on demand. They can read + execute it; not modify or delete.
- Update-MachineNumber.ps1 writes now have -ErrorAction Stop so
PermissionDenied actually fires the catch block instead of being
swallowed.
- 02-MachineNumberACLs.ps1 gutted to a no-op (left in place for
Stage-Dispatcher discovery; no longer grants the ACLs). Old bays'
existing grants are harmless since SYSTEM ignores them.
- Register-CheckMachineNumberTask.ps1 now installs both tasks AND
unregisters the legacy 'Check Machine Number' task name on
re-imaging. Run-ShopfloorSetup.ps1's $skipInBaseline list now
includes Prompt-MachineNumber.ps1 + Apply-MachineNumber.ps1 so
they aren't auto-run during the baseline pass (only via the
scheduled tasks).
Smoke tested end-to-end on win11 VM with ShopFloor (Limited) logging in
interactively: AtLogOn trigger fired Prompt, dialog rendered, tech
typed 7777, schtasks /run succeeded (the SDDL fix lets Limited users
trigger SYSTEM tasks), Apply ran as SYSTEM, eDNC reg + machine-number.txt
both updated to 7777, result MessageBox shown, Prompt task auto-
unregistered by Apply's cleanup step. No ACL grants needed on any user.
Apply also re-tested with -ErrorAction Stop confirming non-terminating
PermissionDenied now properly throws into the catch + populates Errors[]
+ flips $out.EdncUpdated to false - so any future write failures will
report honestly instead of silently claiming success.
Tech catches a PC imaged with a wrong machine number. Previously the
share restore (NTLARS .reg + UDC settings + UDC live data) only fired
on the placeholder->real transition, so a real->real change rewrote
only UDC JSON, eDNC reg, and MTConnect Devices.xml - leaving the wrong
NTLARS config in place.
Update-MachineNumber.ps1: replace the placeholder-only guard with an
any-change guard so the share restore block fires on reassign too.
The existing one-shot migrated/ consumption keeps live-data restore
idempotent. Also writes C:\Enrollment\machine-number.txt to keep
imaging-time scripts in sync.
Set-MachineNumber.ps1 (both collections + nocollections): show a
confirmation dialog when reassigning between two real numbers, naming
old/new and listing what gets pulled. Audit each call to
C:\Logs\Shopfloor\reassign.log.

Pairs with Phase 1+2 from earlier (alias maps in Install-FromManifest,
GE-Enforce, Get-PCProfile, verify-state). See project-shopfloor-rename-reorg
memory for the plan.
Phase 3 (repo + paths):
- git mv per-PC-type dirs to gea-shopfloor-* names:
Standard -> gea-shopfloor-collections
CMM -> gea-shopfloor-cmm
Keyence -> gea-shopfloor-keyence
Genspect -> gea-shopfloor-genspect
WaxAndTrace -> gea-shopfloor-waxtrace
Display -> gea-shopfloor-display
Lab -> gea-shopfloor-common (folded; Timeclock+Lab merge)
- New gea-shopfloor-nocollections/ (clone of collections sans UDC scripts).
- New gea-shopfloor-heattreat/ (placeholder, README only).
- Move Standard/ntlars-backups/ -> _ntlars-backups/ (per-MN, not per-type).
- Run-ShopfloorSetup.ps1: Resolve-PCTypeDir helper walks alias group when
the on-disk dir for the current pcType is missing. Set-MachineNumber
helper-copy gated on collections|nocollections|legacy Standard-Machine.
- Update-MachineNumber.ps1: pcProfiles lookups try gea-shopfloor-collections
first, fall back to legacy Standard-Machine. PowerShell 5.1 compatible
(no null-coalesce).
Phase 4 (startnet.cmd menu):
- Choice 3 "GEA Shopfloor" now drills into a 9-item sub-menu instead of
going straight to enrollment. Sub-cats:
1. Machine with Collections -> gea-shopfloor-collections
2. Machine without Collections -> gea-shopfloor-nocollections
3. Common (Timeclock, Lab) -> gea-shopfloor-common
4. Keyence -> gea-shopfloor-keyence
5. CMM -> gea-shopfloor-cmm
6. Genspect -> gea-shopfloor-genspect
7. Heattreat -> gea-shopfloor-heattreat
8. Wax and Trace -> gea-shopfloor-waxtrace
9. Display -> gea-shopfloor-display
- Office menu (existing 6-option) follows for every sub-cat.
- Machine number prompt only for collections + nocollections.
- pc-subtype.txt + display-type.txt no longer written. PCTYPE is a
single full string (gea-shopfloor-*); subtype-aware code paths fall
back to empty and resolve via the alias map.
- CMM bootstrap stage gate switched from "%PCTYPE%"=="CMM" to
"%PCTYPE%"=="gea-shopfloor-cmm".
Test harness:
- B-enforce/run.sh PCSUBTYPE default changed from "Machine" to "" so
single-arg invocation matches the new single-string scheme. Two-arg
legacy form ("Standard Machine") still works via aliasing.
- B-enforce/tamper.ps1 alias-aware Test-MatrixEntryMatches mirroring
verify-state.ps1.
Smoke-tested on win11 VM as SYSTEM via qga: B-enforce harness 5-phase
cycle (stage / baseline / tamper / heal / idempotent) passes 10/10
with PCType=gea-shopfloor-collections AND with legacy "Standard Machine"
two-arg form.

When the tech transitions a 9999-placeholder PC to its real machine number,
also restore the per-bay udc_settings_<num>.json from
\\tsgwp00525\shared\spc\udc\settings_backups\. PXE-time preinstall can't reach
this share (no SFLD creds yet), so 00-PreInstall uses the local C:\Enrollment
mirror; post-config the share is reachable, so the renumber path goes direct
to the canonical source.
Adds udcSettingsSharePath to site-config.json under Standard-Machine.
Bundles in prior uncommitted work in the same file: ntlars reg restore,
UDC data restore (CurrentData.json + ArchivedData/), MTConnect Devices.xml
inline rewrite + service restart, and one-shot consume of per-bay UDC
backup -> migrated/<timestamp>/.
Root cause found via decompiling UDC_Setup.exe: it never writes
udc_settings.json from CLI args. Instead it pulls
Settings_Backups\udc_settings_<num>.json from \\tsgwp00525\shared\SPC\UDC
-- which is unreachable at imaging time (no SFLD creds yet). Silent
File.Exists() false, settings never copy, UDC lands on Evendale defaults.
Fix: stage 80 udc_settings_*.json backups under
shopfloor-setup/Standard/udc-backups/ (same tree as ntlars-backups,
xcopy'd to C:\Enrollment\ by existing startnet.cmd). 00-PreInstall
pre-creates C:\ProgramData\UDC\udc_settings.json from the matching
backup BEFORE UDC_Setup.exe runs. Installer's server-side copy silently
fails (unreachable), our pre-staged file survives.
Also:
- preinstall.json UDC InstallArgs corrected: "West Jefferson" -9999
(quoted spaced site + dash-prefixed number, confirmed via decompile)
- Update-MachineNumber.ps1 UDC.exe relaunch: quoted site + dash number
- Monitor-IntuneProgress: action prompts (Select Device Category after
Phase 1; Initiate ARTS Lockdown after Phase 5/creds), Display flow
(3-phase: Registration -> Config -> Lockdown), Phase 6 IME-based
lockdown detection

UDC_Setup.exe and UDC.exe expect:
UDC_Setup.exe WestJefferson -7605
Not the spaced-quoted positional pair we'd been passing:
UDC_Setup.exe "West Jefferson" 7605
The wrong format meant UDC ignored both args, fell back to defaults
(Site=Evendale, MachineNumber=blank). Combined with the kill-after-detect
window, neither value got persisted to udc_settings.json regardless of
whether UDC.exe was given time to write.
Changes:
- preinstall.json: UDC InstallArgs now "WestJefferson -9999"
- 00-PreInstall-MachineApps.ps1: site override now matches/replaces
the compact 'WestJefferson' token (not 'West Jefferson') and uses
siteNameCompact from site-config; targetNum extraction regex updated
to '-(\d+)$' for the new dash-prefix format
- Update-MachineNumber.ps1: UDC.exe relaunch now passes positional
compact-site + dash-prefixed number instead of -site/-machine flags
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- 03-ShellDefaults.ps1: Default-User TaskbarAl=0 (left), HKLM policies to
hide Start Recommended section, kill Bing web search + suggestions,
disable Cortana. LTSC-honoured; runs fleet-wide via baseline loop.
- ntlars-backups/: 147 per-machine eDNC registry backups renamed to
flat <MachineNumber>.reg scheme. Historical off-by-one entries from
the original dump rewritten to match CSV-target MachineNo.
- Standard/03-RestoreEDncConfig.ps1: at imaging time, if tech typed a
real machine number at PXE (not 9999), import <num>.reg from the local
staged copy. Restores eFocas IP, PPDCS serial, Hssb relays -- not just
the bare MachineNo. Skipped on Timeclock / 9999 / missing backup.
- Update-MachineNumber.ps1: when tech later sets a real number from 9999,
pull <num>.reg from tsgwp00525 SFLD share (ntlarsBackupSharePath in
site-config) and reg-import it before writing the new MachineNo.
- Restore-EDncReg.ps1: shared helper (Mount-SFLDShare + Import-EDncRegBackup)
used by both callers.

Three optimization batches from the pipeline audit:
1. Shared Update-MachineNumber.ps1 helper (lib/)
Extracts duplicated machine-number update logic from Configure-PC.ps1,
Check-MachineNumber.ps1, and Set-MachineNumber.ps1 into a shared
dot-sourceable helper at Shopfloor/lib/Update-MachineNumber.ps1.
Exports:
Get-CurrentMachineNumber → @{ Udc = $string; Ednc = $string }
Update-MachineNumber -NewNumber <n> [-Site <s>] → @{ UdcUpdated; EdncUpdated; Errors }
All three consumers now dot-source the helper instead of duplicating
~50 lines each. Set-MachineNumber.ps1 also migrated from inline
Get-SiteConfig to dot-sourcing Get-PCProfile.ps1 for consistency.
2. Site-config integration for remaining scripts
Setup-OpenText.ps1: exclude lists (profiles + shortcuts) now read from
site-config.json opentext section, falling back to West Jefferson
defaults. Inline Get-SiteConfig since the script runs from
C:\PreInstall\installers\opentext\ (can't dot-source Get-PCProfile).
00-PreInstall-MachineApps.ps1: after parsing preinstall.json, scans
InstallArgs for "West Jefferson" and replaces with site-config
siteName if different. Inline Get-SiteConfig for same reason.
3. Placeholder type-specific directories
Created skeleton 01-Setup-*.ps1 scripts for all PC types so the
directory structure is in place and Run-ShopfloorSetup's type-specific
loop has something to iterate over:
Genspect/01-Setup-Genspect.ps1
Keyence/01-Setup-Keyence.ps1
WaxAndTrace/01-Setup-WaxAndTrace.ps1
Lab/01-Setup-Lab.ps1
Each logs a "no type-specific apps configured yet" banner and exits.
Fill in app installs when details are finalized; for share-based
installs, copy the CMM/01-Setup-CMM.ps1 pattern.
