## Session Summary
Diagnosed slow performance on Lupe Sanchez's workstation **DESKTOP-TRCIEJA** (Cascades of Tucson), reported as the machine being slow when opening Excel files on the desktop. Located the agent via `rmm-search` (GuruRMM agent `c9bf1a2d-bfdc-401e-9cc8-f9e90bb19587`, online, Windows 11 Pro build 22000) and ran a full performance diagnostic over the GuruRMM agent in SYSTEM context.
The diagnostic identified two converging root causes. First, the hardware is end-of-life: a Gateway ZX6971 all-in-one with an **Intel Core i3-2120 (Sandy Bridge, 2011, 2C/4T)** and **8 GB RAM with only ~2.1 GB free** (27%), running Windows 11 on an unsupported CPU. The SSD itself (DREVO X1 SSD, 224 GB, 44% free) is healthy. Second, and the direct cause of slow Excel opens, the machine is running **two real-time antivirus engines simultaneously**: ACG's Bitdefender Endpoint Security Tools (keep) plus the previous MSP's leftover Datto stack, which bundles a real-time scanner. Both engines scan every file on access, and on a weak 2-core CPU under memory pressure that produces the exact "slow to open Excel" symptom. OneDrive was ruled out — the desktop is local (`C:\Users\LupeSanchez\Desktop`, 50 files / 278 MB, no cloud placeholders), not redirected via Known Folder Move.
Recon of uninstall entries showed the "Datto AV" reported by SecurityCenter2 is actually the leftover Datto EDR/RMM stack: **Datto RMM (CentraStage)**, **Datto EDR Agent (Infocyte)**, and the bundled **Endpoint Protection SDK (DattoAV)** under `C:\Program Files\infocyte\agent\dattoav\`. The Cascades wiki already flags this same leftover Datto (CentraStage + Infocyte) stack for fleet-wide cleanup. Bitdefender (v8.26.6.644, services running) is properly installed.
I proposed removing the leftover Datto stack in order (RMM -> EDR -> AV SDK, so Datto RMM cannot re-push the AV) and disabling the Adobe Acrobat PDFMaker Excel add-in. Before acting on a security/management-agent removal I asked Howard to confirm scope. **Howard declined all changes** — the decision is to replace the machine instead. No changes were made to the endpoint; this was diagnostic-only.
## Key Decisions
- **No remediation performed — machine to be replaced.** Given the 2011-era i3-2120 / 8 GB hardware is EOL and unsupported for Win11, Howard opted to order a replacement rather than spend time uninstalling the Datto stack on a box being retired.
- **Split the diagnostic into small section scripts.** A combined ~7 KB multi-line PowerShell body failed agent-side (exit -1, "Failed to execute command"); breaking it into <2 KB section scripts (`diag_a/b/c`) each ran cleanly. Logged as friction in `errorlog.md`.
- **Ruled out OneDrive/Known Folder Move early** — desktop is local with no cloud placeholders, so the slowness is not on-demand-file hydration.
- **Identified dual real-time AV as the direct cause** of slow Excel opens, distinct from the hardware weakness.
## Problems Encountered
- **Heredoc quoting failure** building the combined diagnostic inline in Bash ("unexpected EOF") due to embedded single quotes — switched to writing the script to a file and feeding it via `jq --rawfile`.
- **Agent rejected the large combined script** (exit -1, "Failed to execute command") despite only ~7 KB and valid syntax; a minimal sanity command ran fine, confirming the agent chokes on a large multi-line `-Command` body. Resolved by splitting into three small section scripts. Logged via `log-skill-error.sh ... --friction`.
## Configuration Changes
- **Endpoint (DESKTOP-TRCIEJA): none.** Diagnostic-only; no software removed or settings changed.
- Repo: created and then deleted temporary diagnostic scripts in the working tree (`diag_perf.ps1`, `diag_a.ps1`, `diag_b.ps1`, `diag_c.ps1`, `diag_recon.ps1`) — none committed.
- `errorlog.md`: appended one `--friction` entry (rmm large-command-body failure).
## Credentials & Secrets
None discovered or created this session. RMM auth via existing vault path `infrastructure/gururmm-server.sops.yaml` (unchanged).
## Infrastructure & Servers
- **DESKTOP-TRCIEJA** — Lupe Sanchez workstation, Cascades of Tucson, site CascadesTucson.
- GuruRMM agent ID: `c9bf1a2d-bfdc-401e-9cc8-f9e90bb19587` (resolve live by hostname; UUIDs change on re-enroll). Agent version 0.6.66.
- Hardware: Gateway ZX6971 AIO, serial `DOGDGAA0012200249A6300`, Intel i3-2120 2C/4T, 7.9 GB RAM, DREVO X1 SSD 224 GB (Healthy, SMART PredictFailure=False), C: 97.2 GB free of 222.8 GB.
- OS: Windows 11 Pro build 22000 (i3-2120 not Win11-supported).
- Active console user: `lupesanchez` (profile `C:\Users\LupeSanchez`).
- **Leftover Datto stack (previous MSP, flagged for cleanup):**
- Datto RMM (CentraStage) — service `CagService`, uninstall `C:\Program Files (x86)\CentraStage\uninst.exe` (NSIS, `/S`).
- Datto EDR Agent (Infocyte) v3.17.1.5409 — uninstall `"C:\Program Files\infocyte\agent\agent.exe" --uninstall`.
- Endpoint Protection SDK / DattoAV v1.0.2510.6851 — quiet uninstall `"C:\Program Files\infocyte\agent\dattoav\Endpoint Protection SDK\endpointprotection.exe" uninstallSdk`.
- **Bitdefender (ACG, keep):** Endpoint Security Tools v8.26.6.644; services EPSecurityService / EPProtectedService / EPRedline running. Defender in passive state (correct).
- **Excel/Office:** Microsoft 365 Apps for business 16.0.20026.20168; `EXCEL.EXE` at `C:\Program Files\Microsoft Office\Root\Office16\`.
- Network note: System log shows recurring Event 2505 — duplicate computer name on the network ("another computer on the network has the same name").
## Commands & Outputs
- `bash .claude/scripts/rmm-search.sh desktop-trcieja` -> 1 match, Cascades of Tucson, online.
- Diagnostic dispatched cmd `c31c6552-1abd-41eb-b269-159cab42360d` (combined script) -> **failed exit -1** "Failed to execute command".
- Sanity cmd `acb9eba4...` -> `PONG from DESKTOP-TRCIEJA as nt authority\system`; `quser` -> `lupesanchez console 1 Active`, logon 6/18/2026 9:27 AM.
- Section scripts ran clean. Top processes by memory: EXCEL 540 MB, Memory Compression 427 MB, EPSecurityService (Bitdefender) 408 MB / 589 CPU-s, OUTLOOK 349 MB, endpointprotection (DattoAV) 333 MB / 611 CPU-s, AEMAgent (Datto RMM) 132 MB.
- AV via SecurityCenter2: Datto AV (multiple states), Windows Defender (0x60100 passive), Bitdefender Endpoint Security Tools.
- `Get-MpComputerStatus`: Defender RTP False, SigAge 65535 (Defender stood down — expected with Bitdefender present).
- Excel add-ins (user LupeSanchez): Adobe PDFMaker LoadBehavior=3 (loaded), MicrosoftDataStreamerforExcel, PowerPivotExcelClientAddIn.
- Disk/stability events (7d): Event 98 x13, Event 153 x4, Event 11 x2 — occasional SATA I/O retries (SMART healthy).
- `log-skill-error.sh "rmm" "...large multi-line powershell body fails exit -1; split into <2KB section scripts" --friction` -> logged.
- Two `[RMM]` bot alerts posted to #dev-alerts (dispatch + result summary).
## Pending / Incomplete Tasks
- **Order replacement workstation for Lupe Sanchez** (Howard's action). EOL i3-2120 / 8 GB.
- On the new machine: provision GuruRMM + Bitdefender only; do **not** carry over the Datto stack (CentraStage + Infocyte/DattoAV).
- Fleet-wide at Cascades: the leftover Datto (CentraStage + Infocyte) cleanup remains open per the wiki — DESKTOP-TRCIEJA is another instance of it.
- Optional follow-ups (now moot if replacing): resolve duplicate computer name on the network (Event 2505); the Acrobat PDFMaker add-in remains enabled.
- No wiki/ticket entry created this session (offered, not requested).
