Session 2026-06-13 — VWP SERVER3 retirement, G: migration to VWP-FILES, Orders VB6 source recovery (+ GuruRMM NT 6.0 legacy agent)

Session Summary

Started on the GuruRMM legacy-agent floor: SERVER3 rejected the legacy agent with "not a valid Win32 application." Confirmed the cause is the PE OS/subsystem version stamp (6.1 = Win7/2008 R2) vs the box's NT version. Built a 6.0-stamped legacy agent on Pluto (the office Windows builder) so the agent loads on Server 2008 / NT 6.0 — needed for Glaztech's pre-R2 2008 servers. Two real fixes were required: pin zeroize = =1.8.1 (1.9.0 needs edition2024, which Rust 1.77 can't parse — a latent break in the production legacy pipeline) and add -C link-arg=/SUBSYSTEM:CONSOLE,6.00. Header verified 6.0/6.0, console subsystem preserved.

SERVER3 (the VWP XenServer "server 2003" VM) was upgraded in-place to Server 2008 by Mike. That broke networking (PV NIC gone) and then bricked with 0x7B INACCESSIBLE_BOOT_DEVICE after a XenTools install. Recovered it: safe-mode XenTools uninstall, then a clean reinstall with the xenbus/ xenfilt/xenvbd boot-start fix applied before reboot. Came up healthy (PV 7.1 build 1270, NIC up on 192.168.0.20). Snapshots taken at each safe point.

The main work: migrated the G: file share off SERVER3 onto a new Hyper-V file server, VWP-FILES (pre-staged Gen2 Server 2019 VM on VWP-HYPERV1). Block-migrated the 100 GB G: VDI (XenServer vdi-export streamed straight to HYPERV1 over HTTPS, converted to VHDX), attached, brought online, recreated all 19 SMB shares with exact perms (via WMI ACL extraction — the registry-import route was blocked by SMB admin-share refusal), repointed the MappedDrives GPO G: → \\VWP-FILES\G-drive (and cleaned two stale G: maps), and did the IP takeover so VWP-FILES holds 192.168.0.20 (VLAN 2 "Old Net") for IP-based stragglers while serving the new net on 172.16.9.132. Verified, billed 3.5 h remote on #32418, prepay 24.0 → 20.5.

Finally, hunted for the lost VWP "Orders" VB6 source (#32280). It was not loose on any server — but Darv's full machine backup (F:\Darv\Darv.rar, 51 GB, on WINFileSvr) contained the complete Orders project tree. Staged 12.2 MB of pure source (147 .frm, 4 .bas, 5 .vbp; newest ORDERS_C.vbp 2020-06-09) into the repo. The source is fully recovered — VB Decompiler is no longer needed.

Key Decisions

  • 6.0 PE stamp, not a separate agent SKU. A 6.0-stamped image still loads on Win7→11, so one legacy binary covers 2008 → 11 — just lower the floor. Pin zeroize=1.8.1 to clear the edition2024 wall on Rust 1.77 (mirrors the existing uuid/url pins).
  • Block-migrate G:, not file-copy. ~100 GB of many small files → a whole-volume image move (VDI export → VHDX) is far faster and preserves NTFS/perms/timestamps. Streamed the export directly XenServer→HYPERV1 (dom0 has only ~15 GB scratch; can't stage 100 GB locally).
  • WMI ACL extraction for shares, not registry import. SERVER3's admin share (C$) refused (error 67) and reg export via WMI didn't land, so recreated all 19 shares with New-SmbShare
    • the exact share-level ACLs pulled via Win32_LogicalShareSecuritySetting. Result identical (mostly Everyone Full; Shelly read-only; G-drive +Domain Users).
  • GPO points G: at \\VWP-FILES by name, decoupled from the .20 IP takeover, so it survives regardless. Disabled DNS registration on the .20 NIC so the name resolves only to 172.16.9.132 (avoids new-net clients hitting the asymmetric-route dead end on .20).
  • IP takeover via VLAN tag, no cabling. UDM "Old Net" = VLAN 2; HYPERV1's uplink already trunks it (UniFi default), so a tagged 2nd vNIC + .20 was fully remote — no on-site patch needed.
  • Don't decompile — recover the source. Pursued Darv.rar over the VB-Decompiler path once the full .vbp tree turned up; we now have real, buildable 2020 source.

Problems Encountered

  • "not a valid Win32 application" on SERVER3 — PE stamped NT 6.1; box was below the floor. Fixed by building a 6.0-stamped agent (and SERVER3 was upgraded to 2008 anyway).
  • 0x7B INACCESSIBLE_BOOT_DEVICE after XenTools on the 2008 guest — xenvbd took the boot disk without being boot-critical. Fixed by setting xenbus/xenfilt/xenvbd Start=0 before reboot.
  • zeroize 1.9.0 edition2024 broke the 1.77 legacy build — pinned =1.8.1. (Production legacy pipeline will hit the same; the pin should be committed to agent/Cargo.toml.)
  • RMM JSON transport eats one backslash from UNC literals — bit me 3× (GPO path stored as \VWP-FILES, Test-Path failures). Worked around by building backslashes from [char]92.
  • Asymmetric routing to .20 — dual-homed VWP-FILES replies via its 172.16.9 NIC, so cross-subnet (DC, my VPN) can't reach .20; only same-subnet Old-Net clients can. Acceptable: stragglers are Old-Net, new-net uses the GPO \\VWP-FILES. Used 172.16.9.132 for my own file pulls.
  • SMB admin-share (C$) refusal + reg-export-via-WMI not landing on SERVER3 → pivoted to WMI ACL extraction for the share migration.
  • Per-site MSI installer endpoint 500/"Missing authorization" when enrolling VWP-FILES — Mike pushed the agent via ScreenConnect instead (now online, site Main Office).

Configuration Changes

  • VWP-FILES (Hyper-V VM on VWP-HYPERV1): checkpoint merged (flat VHDX), AutomaticCheckpoints disabled, RAM 4→16 GB, install ISO ejected. Added 2nd vNIC OldNet-VLAN2 (AccessVlanId 2), static 192.168.0.20/24 (no gateway), DNS registration disabled on that NIC. Attached migrated C:\VHD\server3-g.vhdx (SCSI0:2) as G:. 19 SMB shares created. GuruRMM agent installed (via SC).
  • GPO MappedDrives (VWP.US): G: drive map \\192.168.0.20\G-drive → \\VWP-FILES\G-drive; version bumped (gpt.ini + AD) to 4980736.
  • GPO Default Domain Policy: removed stale G: map (\\192.168.0.96\g$); version → 1114165.
  • Orphaned SYSVOL policy {FCB17CA3-155F-4BD3-B633-4E1F5CF01679} (no AD object) deleted (backed up to C:\GPO-backup-Gmig-20260613-170451 on VWP-DC1).
  • SERVER3 (XenServer VM 0c73ce00-...): clean-shutdown (retired). Snapshots created: server2008-clean-noTools-20260613 (45d56386), server2008-working-pvtools-20260613 (b2f50da4).
  • Repo: staged clients/valleywide/app-modernization/source-code/Orders-VWP_Current-2020/ (12.2 MB recovered VB6 source); darv-G-finds/ (ORDERS0727-2015.exe, ORDERS-2005.exe, frmPayroll, Package1508); updated app-modernization/CONTEXT.md (G: finds + source recovery).
  • Vault: created clients/vwp/domain-sysadmin (VWP\sysadmin).

  • Source recovery sweep found …\Kingston\Project\VWP_Current\ORDERS_C.vbp (2020-06-09); project references 80 forms + 10 OCX (TABCTL32, Crystl32, True DBGrid, FarPoint Spread).

Pending / Incomplete Tasks

  • Commit zeroize = "=1.8.1" to guru-rmm/agent/Cargo.toml (production legacy build will break on next run without it). Open as its own fix.
  • Validate the 6.0 legacy agent on a real NT 6.0 box (Glaztech 2008 server, or a lab VM). Then correct SPEC-029 §12 / installer/legacy/README.md ("blocked / NSIS+NSSM") and pursue unified x86-MSI + native-SCM.
  • Modernization (#32280): stand up a VB6 build env, confirm ORDERS_C.vbp compiles from the recovered tree, then scope the modernization from source. Optionally stage VWP_Inv / VWP_Update projects too. Bill #32280 for the recovery search.
  • Cleanup (on sign-off): delete C:\VHD\server3-g.vhd (99 GB intermediate) on HYPERV1, the XenServer G: snapshot, and F:\Darv\Darv-rar (135 GB) once source verified; SERVER3 VM stays off-but-intact as deepest rollback.
  • Commit the staged source + darv-G-finds (this /save syncs them).
  • Beast C:\Temp\gururmm-nsvc* leftovers from the prior native-SCM probe still pending cleanup.
  • Old-Net DHCP secondary DNS = 8.8.8.8 → consider changing to a second internal DC.

  • Created wiki article: wiki/projects/valleywide-orders-modernization.md (app domain, stack, recovered-source status + locations, modernization assessment + first concrete steps, sources).
  • Linked from wiki/index.md (Projects table) and wiki/clients/valleywide.md (app-mod section pointer + "source RECOVERED" note superseding the old "lost" text).
