## Session Summary

Started with a Syncro billing task: Four Paws (vet clinic, customer id 33050383) had a missing Avimark desktop shortcut. The Avimark install was located at `C:\avimark` and a new desktop shortcut was created. Created ticket #32508 and invoice #67993 (0.5h remote labor, $75.00) via the `/syncro` skill.

The user then provided full inventory detail for the Four Paws "Server" machine, including the localadmin credential (`r3tr0gradE99#`, auto-login). A vault entry (`clients/four-paws/localadmin`) already existed with a matching password (set up by Mike 2026-06-23); it was enriched with host-identification details (model, serial, IPs, MAC, Syncro id) and the auto-login status.

The user requested removing the localadmin password (blank) while keeping it as the default/auto-login account. Before changing, a read-only recon confirmed nothing depended on localadmin for shares — the AVImark share (`\\SERVER\AVImark`) is served to the `staff` and `avimark` local accounts via workgroup pass-through, and no workstation had mapped drives or stored cmdkey credentials referencing localadmin. The password was blanked (`net user Localadmin ""`), set to never-expire, and Winlogon auto-login re-armed with a blank DefaultPassword. `LimitBlankPasswordUse=1` was left at its secure default.

A reboot to verify auto-login revealed the blank password BROKE auto-login — Windows 11 `AutoAdminLogon` does not proceed with an empty `DefaultPassword`; the server stalled at the logon screen (no console session after ~4 min uptime). Per the user's decision, the original password `r3tr0gradE99#` was restored and stored for auto-login, then reboot-tested: auto-login confirmed working (localadmin on console, explorer + WMI console owner = SERVER\Localadmin). All three RMM-enrolled machines (SERVER, STATION2, DESKTOP-3T5P291) were rebooted per the user request.

Finally, the user asked why machines were missing from GuruRMM and to add them. A network sweep from SERVER identified 4PAWS-DOC (192.168.0.148, Dell Vostro 3910) as an unmanaged Windows workstation and FOVEADR-DR5258X (192.168.0.248) as a vet radiography imaging appliance. 4PAWS-DOC was in ScreenConnect, so the GuruRMM agent was deployed via SC send-command. The first attempt failed because the box was thread-exhausted (`0x800700a4 No more threads can be created`); a reboot cleared it and the re-run enrolled 4PAWS-DOC successfully (agent id 79d5243b). An onboarding diagnostic was run on 4PAWS-DOC (Grade AMBER, 0 critical / 3 warning).

## Key Decisions

- Blanked localadmin password only after read-only recon proved shares use the `staff`/`avimark` accounts, not localadmin — so blanking could not break file sharing (`LimitBlankPasswordUse=1` confines a blank-password account to console-only anyway).
- Restored the localadmin password after empirically proving blank-password + AutoAdminLogon is impossible on this Windows 11 build. Chose the original `r3tr0gradE99#` (known-good, already documented) to return to a proven state. Auto-login = "no password needed to log in" in practice, which was the user's underlying goal.
- Did NOT enroll FOVEADR-DR5258X (Fovea DR X-ray imaging appliance) — RMM agents should not be dropped on vet imaging equipment without vendor confirmation; also not in ScreenConnect.
- Deployed the GuruRMM agent to 4PAWS-DOC via ScreenConnect send-command (site one-liner) rather than RMM push, because the box had no existing agent.
- Rebooted 4PAWS-DOC to clear thread exhaustion rather than retrying the enroll command (command delivery was fine; the machine was degraded).

## Problems Encountered

- **Blank-password auto-login failure:** After blanking localadmin's password, the server stalled at the logon screen on reboot. Root cause: Win11 `AutoAdminLogon` will not proceed with an empty `DefaultPassword`. Resolved by restoring the password and re-storing it for auto-login; reboot-verified.
- **4PAWS-DOC enroll failure (`0x800700a4`):** GuruRMM install one-liner died at `Get-CimInstance Win32_Processor` with "No more threads can be created in the system" (ERROR_MAX_THRDS_REACHED). The box was resource-exhausted from long uptime. Resolved by rebooting the machine (down ~6 min, applied pending updates) and re-running the enroll — succeeded. Logged to errorlog.md.
- **iconv missing on Howard-Home:** `ps-encoded.sh rmm` failed (`iconv: command not found`). Worked around by encoding the PowerShell script to UTF-16LE base64 with `py` and dispatching `powershell.exe -EncodedCommand <b64>` directly.

## Configuration Changes

- **Four Paws SERVER (192.168.0.5):** localadmin password blanked then restored to `r3tr0gradE99#`; set PasswordNeverExpires; Winlogon auto-login re-armed (AutoAdminLogon=1, DefaultUserName=Localadmin, DefaultDomainName=SERVER, DefaultPassword=r3tr0gradE99#). Net state = unchanged from pre-session (password restored). Rebooted.
- **STATION2, DESKTOP-3T5P291:** rebooted (no config change).
- **4PAWS-DOC (192.168.0.148):** GuruRMM agent installed + enrolled (Four Paws / Main); rebooted once to clear thread exhaustion.
- **Vault `clients/four-paws/localadmin.sops.yaml`:** enriched with host details; password field cycled blank -> restored to `r3tr0gradE99#`; auth_note documents the blank-password/autologon incompatibility.
- **New file:** `clients/four-paws/onboarding-baselines/4PAWS-DOC-20260708T193830.{json,md}` (diagnostic baseline).

## Credentials & Secrets

- **Four Paws SERVER localadmin:** username `Localadmin`, password `r3tr0gradE99#` (restored; auto-login account). Vault: `clients/four-paws/localadmin`.
- **Four Paws staff workgroup account:** username `staff`, password `avimark!` (intra-machine SMB/printer auth; also a local admin on 4PAWS-DOC). Vault: `clients/four-paws/staff-workgroup`.
- No new credentials created this session.

## Commands & Outputs

- Blank password: `net user Localadmin ""` + `Set-LocalUser -PasswordNeverExpires $true` + Winlogon New-ItemProperty (DefaultPassword=""). Result: auto-login broke (logon screen).
- Restore: `net user Localadmin 'r3tr0gradE99#'` + Winlogon DefaultPassword=pw. Reboot -> `query user` shows `localadmin console Active`; `Win32_ComputerSystem.UserName = SERVER\Localadmin`.
- Network sweep (SERVER): async ping 1..254 + nbtstat. Found 4PAWS-DOC (.148), FOVEADR-DR5258X (.248), printers/router.
- SC enroll: `send-command --session 0bb9172c... --command 'powershell ... iex (irm https://rmm.azcomputerguru.com/install/COPPER-HAWK-2085/windows)'`.
  - First attempt error: `Get-CimInstance : No more threads can be created in the system. HRESULT 0x800700a4` at line 30 (Win32_Processor).
  - Fix: `shutdown /r /t 5 /f` via SC; wait ~6 min; re-send enroll -> enrolled (79d5243b).
- Diagnostic: `run-onboarding-diagnostic.sh 4PAWS-DOC four-paws` -> AMBER, 0 crit / 3 warn.

## Pending / Incomplete Tasks

- 4PAWS-DOC AMBER warnings (not remediated — user declined for now): BitLocker OFF on C:, 2 pending Windows updates, Intel Platform License Manager service stopped (benign). Also: `staff` is a local admin (shared cred), no backup agent detected, W32Time service stopped.
- FOVEADR-DR5258X imaging appliance: confirm with vendor whether it should be managed/backed up.
- Workstations (SERVER, STATION2, DESKTOP-3T5P291, 4PAWS-DOC) need AVImark relaunched by staff after the reboots.
- SERVER clock read ~6h ahead of expected during the session — possible time-sync drift worth checking.
