Session Summary
Julie reported "no printers" on RSW-Laptop. Via GuruRMM, confirmed Spooler + ZeroTier running, then established that the only real printer is \\front\Sharp (Point-and-Print off FRONT; physical Sharp MX-B557F at office LAN 192.168.1.158). Exhaustively verified the path: ZeroTier up, name resolves (front→10.147.19.199), TCP 445/139 open, MTU 2800 carries full DF packets (MTU ruled out), FRONT healthy (spooler running, Sharp shared, profile Private, SMB-In allowed), laptop ZT adapter bindings (ms_msclient/ms_server) all present, both ends' ZT profile Private. Yet net use \\front\IPC$ (and by IP) fails with System error 67 and net view with RPC 1702 — and error 67 persists even with valid FRONT\julie credentials, ruling out auth/firewall/MTU/bindings/profile. Rebooted both machines mid-session (user request); did not change it.
Mike flagged this as a failure of the session-logs/wiki systems — we "spent two days" on this user/laptop. Investigation showed the work WAS captured but the client was fragmented across four slugs (wolkin, wolkin-law, rswolkin, robert-wolkin), so neither recall nor I found it, and I re-derived a diagnosis that the 2026-06-07 log already had. That log showed the same error 67 / RPC 1702 and that Mike cleared it by connecting \\front\Sharp manually/interactively (scripted Add-Printer failed there too). It also flagged "migrate front\julie creds to vault" and "consolidate the slugs" as pending — never actioned.
Per Mike's "Do all", executed the full remediation: (1) restore-printer test with the recovered credential — confirmed error 67 is NOT auth, so the scripted path can't fix it (needs ScreenConnect/interactive, same as before); (2) vaulted front\julie + the M365 user passwords; (3) consolidated the four slugs into canonical wolkin (moved logs/baselines, merged + corrected the wiki, stubbed the duplicates), corrected a cross-client agent-id error, and wrote a memory so this fragmentation failure doesn't recur.
Key Decisions
- Canonical slug =
wolkin. Moved allrswolkin/wolkin-lawlogs+baselines intoclients/wolkin/; left README pointer stubs; merged 3 wiki articles intowiki/clients/wolkin.mdwithaliases:for recall; stubbedwolkin-law.md+robert-wolkin.md. - Did NOT keep chasing the error-67 SMB quirk scripted — it's a documented wall requiring an interactive fix; logged it loudly in the wiki Patterns instead of burning more cycles.
- Vault secrets only under
credentials:via the newvaultskill helper; infra facts stay in the wiki (plaintext, searchable). - Recommend rotating
front\juliesince its password transited the RMM command log during the authenticated-mount test.
Problems Encountered
- Error 67 / RPC 1702 SMB wall (RSW-Laptop → FRONT over ZeroTier): all underlying layers verified healthy; persists with valid creds. Same as 2026-06-07. Resolution: interactive/ScreenConnect connection (pending); root cause of the redirector quirk still unidentified.
- Client-slug fragmentation: one client under 4 slugs → 2-day build looked lost. Consolidated. Memory written (
feedback_client_slug_fragmentation.md). - Cross-client data error: retired
wolkin-law.mdlisted FRONT's RMM agent id as04765560-…= actually Rednour's FrontDeskReception. Corrected (FRONT =877d311a-…). - Plaintext creds in wiki:
wolkin-law.mdheld robert/julie passwords in clear — moved to vault, scrubbed by stubbing the file. Get-NetAdapterBinding -Name "ZeroTier One [..]"returns empty — the[ ]in the adapter name are PowerShell wildcards; query by-InterfaceDescription "ZeroTier Virtual Port"or pipe the adapter object. (This made me twice misread the bindings as missing.)
Configuration Changes
- Vault (new):
clients/wolkin/front-julie.sops.yaml(front\julie local acct);clients/wolkin/m365-users.sops.yaml(robert@/julie@ rswolkin.com). - Repo moves:
clients/rswolkin/*andclients/wolkin-law/session-logs/*→clients/wolkin/(session-logs, onboarding-baselines, remote-printing-tailscale-plan.md). README stubs left inclients/rswolkin/,clients/wolkin-law/. - Wiki: rewrote/enriched
wiki/clients/wolkin.md(canonical — added GuruRMM agent IDs + Site ID, tenant, error-67 Patterns entry, vault pointers, consolidation banner, 2026-06-11 history). Stubbedwiki/clients/wolkin-law.md+wiki/clients/robert-wolkin.md→[[wolkin]]. - Memory:
feedback_client_slug_fragmentation.md+ MEMORY.md index line. - No repo code changes; RMM dispatches were read-only diagnostics + the two reboots.

Pending / Incomplete Tasks
- [CRITICAL] Restore Julie's printer — reconnect
\\front\Sharpinteractively via ScreenConnect as Julie (scripted hits error 67). This is the actual unresolved issue. - Rotate
front\juliepassword (exposed in RMM command log); re-vault. - Identify/vault
front\Localadminpassword (never recorded). - Root-cause the error-67 SMB-over-ZeroTier redirector quirk (currently worked around manually each time).
- Verify the M365 tenant ID; capture Syncro customer ID + billing model (still
verify).

Update: 08:10 PT — DIAG MISMATCH RESOLVED (printer was working)
Mike remoted into RSW-Laptop (real interactive session) and \front\Sharp printed fine —
contradicting the entire RMM-based diagnosis. Root cause of the mismatch: GuruRMM user_session
is a WTS-impersonated, non-interactive token that cannot establish authenticated SMB to a remote
host, so net use/net view/Add-Printer to \FRONT return error 67 / RPC 1702 regardless of
the (healthy) plumbing and even with valid creds. The RMM tests never reflected Julie's real
session. This also reconciles 2026-06-07 (same artifact; the "manual fix" worked only because it
was interactive — there is no SMB-over-ZeroTier wall).
Corrections made: reframed the wiki Patterns entry from "[KNOWN WALL]" to "[MEASUREMENT ARTIFACT]";
flipped Active Work printer item to WORKING; wrote memory feedback_rmm_user_session_smb_false_negative.md.
The original "no printers" report was likely transient (pre-reboot / momentary ZeroTier hiccup).
Net: nothing was actually broken; the real deliverables this session were the data-hygiene fixes
(consolidation + vaulting) and capturing two reusable lessons. Still open: rotate front\julie.
