+# Cascades NAS->CS-SERVER migration: drive-map skill + CS-SERVER SMB instability diagnosis
+
+## Session Summary
+
+Continued the Cascades of Tucson NAS->CS-SERVER share migration. The session began as a
+single-user task (repoint Karen Rossini's ALDocs shortcut from the NAS to CS-SERVER) and
+turned into a fleet-wide diagnosis of why workstations cannot reliably reach CS-SERVER's
+SMB file shares.
+
+Built a new reusable skill, `drive-map`, to stop re-fighting Windows network drive maps via
+RMM. It runs every operation in the user session (so maps/shortcuts actually appear), stores
+the per-host credential with cmdkey (the workgroup-PC->domain-share case), makes maps
+persistent, repoints/removes stale NAS shortcuts, and verifies access. Validated by dry-run;
+the `verify` verb caught the real blocker before any desktop was touched.
+
+Staged Karen's server-side migration: reset + enabled her domain account
+`CASCADES\karen.rossini` (change-at-logon off), vaulted the password, added her to `SG-IT-RW`
+for RW on `D:\Shares\Server`, and stored a CS-SERVER cmdkey on her PC. The `verify` then
+failed (error 67), kicking off the diagnosis.
+
+Diagnosis chain: ruled out Karen's account, CS-SERVER's firewall (SMB-In Allow/Any), name
+resolution (clean), and L3 routing (`.248` is a direct neighbor). Initially theorized a
+CSC-ENT-vs-CSCNet Wi-Fi segment problem and moved Karen onto CSCNet — but Howard's input
+(Meredith works from CSC ENT; Crystal uses a different access method) plus further testing
+disproved it: fresh SMB connections to `\\cs-server\*` (even `IPC$`) fail with **System error
+67 from BOTH Wi-Fis**, while only pre-existing persistent mapped drives work, and even those
+are intermittent (Meredith's `Y:` read True then False). Conclusion: a **CS-SERVER-side SMB
+instability**, not the client network.
+
+Two additional blockers surfaced: CSCNet is **WPA3-SAE**, so older adapters (Meredith's Intel
+AC 3165) physically cannot join it; and the access model is insecure — workgroup PCs store a
+domain credential (Meredith's stores `cs-server -> administrator`) and the shares are
+`Authenticated Users : Full`.
+
+## Key Decisions
+- Built `drive-map` as a durable skill rather than one-off commands — the repoint recurs for
+  ~7 users. All ops run `context: user_session` by design (the fix for "maps made as SYSTEM
+  are invisible").
+- Reset+vaulted Karen's domain password (she logs in locally, so no disruption) rather than
+  chasing an unknown existing password.
+- Used a reversible, surgical approach to test the network theory (temp host route; vaulted
+  both Wi-Fi PSKs before deleting a profile) so nothing was unrecoverable.
+- Moved Meredith test attempt with a scheduled-task safety net (auto-restore CSC ENT in 15
+  min) to avoid stranding her if CSCNet couldn't carry the agent.
+- Corrected the project memory when the CSC-ENT theory was disproved (memories must not
+  mislead).
+- Deferred the CS-SERVER fix (multichannel interface cleanup, then possible LanmanServer
+  restart) pending Howard's approval — it's a production DC with 13 live sessions.
+
+## Problems Encountered
+- **Karen `verify` error 67** -> root-caused to CS-SERVER SMB instability (see below), not her
+  account or network.
+- **My CSC-ENT-vs-CSCNet theory was wrong** -> disproved when Meredith (CSC ENT) works and
+  fresh connections fail from CSCNet too. Corrected memory.
+- **Moved Karen to CSCNet, broke NAS-by-name for her** -> she can reach NAS by IP but not name
+  now; Howard said she doesn't use the Server folder so left as-is (offer to restore CSC ENT
+  stands).
+- **Meredith cannot join CSCNet** -> WPA3-SAE not supported by her AC 3165 adapter. Plan: buy
+  a new wireless adapter; do not change her connection meanwhile (she needs access).
+- **Self-inflicted friction:** a bash `<<PS` (unquoted heredoc) containing a PowerShell
+  backtick (`` "`n" ``) triggered "bad substitution" and silently sent a broken command. Fix:
+  use `<<'PS'` (quoted) when no bash interpolation is needed, or avoid backticks (use
+  `[Environment]::NewLine`) in unquoted heredocs.
+- **`cmd /c "netsh ... \"quoted\""` mangled quotes** (Windows CommandLineToArgvW) -> call
+  netsh natively from PowerShell; single-quote tokens whose value contains spaces
+  (`'name="CSC ENT"'`).
+
+## Configuration Changes
+- NEW skill: `.claude/skills/drive-map/SKILL.md` + `.claude/skills/drive-map/scripts/drive-map.sh`
+  (verbs: verify | cred | map | shortcut | unmap | migrate; RMM-driven, user_session, vault-read creds).
+- `.claude/memory/project_cascades_network_segments.md` created then corrected; index line in
+  `.claude/memory/MEMORY.md` updated.
+- CS-SERVER (AD): `CASCADES\karen.rossini` password reset + enabled + ChangePasswordAtLogon
+  false; added to group `SG-IT-RW`.
+- Karen's PC (DESKTOP-LPOPV30): CSC ENT Wi-Fi profile deleted + adapter disabled, now CSCNet-
+  only (10.0.20.100). cmdkey `CS-SERVER -> CASCADES\karen.rossini` stored.
+- Meredith's PC (ASSISTMAN-PC): no lasting change (CSCNet profile add failed; safety task removed).
+
+## Credentials & Secrets (vaulted)
+- `clients/cascades-tucson/karen-rossini.sops.yaml` — `CASCADES\karen.rossini` domain pwd (reset
+  this session; temporary, to be changed when she starts using the domain account).
+- `clients/cascades-tucson/wifi-cscnet.sops.yaml` — CSCNet Wi-Fi PSK (WPA3-SAE, 10.0.20.x).
+- `clients/cascades-tucson/wifi-csc-ent.sops.yaml` — CSC ENT Wi-Fi PSK (WPA2-PSK, 192.168.2.x).
+- Note: domain pwd + Wi-Fi PSKs transited RMM command history (internal, admin-only) during
+  provisioning/capture — purge/rotate if needed.
+
+## Infrastructure & Servers
+- CS-SERVER: DC (DomainRole 5), `cascades.local` / NetBIOS `CASCADES`. IPs 192.168.2.248
+  (Ethernet) + 192.168.2.254 (Hyper-V vSwitch), both /22 (192.168.0.0/22). RMM agent
+  c39f1de7-d5b6-45ae-b132-e06977ab1713. Shares under D:\Shares\<name>; Server/Management share
+  ACL = Authenticated Users:Full. SMB multichannel advertises .248, .254, and IPv6 ULAs
+  (fde4::, fd8f::). `Get-SmbServerConfiguration` errors "Data of this type is not supported."
+  SMB signing required. 13 live sessions.
+- Wi-Fi: `CSC ENT` (192.168.2.0/24, gw 192.168.0.1, WPA2) and `CSCNet` (10.0.20.x, gw
+  10.0.20.1, WPA3-SAE). DNS = pfSense 192.168.0.1.
+- Agents: DESKTOP-LPOPV30 (Karen) ad725bb2-d8cb-4a83-8203-6f7e9c906b29; ASSISTMAN-PC
+  (Meredith) cf86fa5e-96a2-494d-9cb1-8be22a518ad0; CRYSTAL-PC ad7d6d5e-fc44-478c-b8e0-0d867844afff.
+
+## Commands & Outputs (key)
+- Fresh `net use \\cs-server\IPC$` -> System error 67 (BAD_NETWORK_NAME), from CSC ENT and CSCNet.
+- Meredith `Test-Path Y:\` -> True, then False minutes later (intermittent persistent mapping).
+- `netsh wlan add profile CSCNet` on AC 3165 -> "security/connectivity setting not supported by adapter" (WPA3).
+- CS-SERVER `Get-SmbServerNetworkInterface` -> .248, .254, fe80::, fde4::, fd8f::.
+
+## Pending / Incomplete Tasks (next session)
+- **CS-SERVER SMB fix (root cause):** (1) clean up SMB interface bindings so it serves only on
+  .248 (unbind File&Printer from .254 vSwitch + IPv6; consider disabling multichannel); (2) if
+  still degraded, restart LanmanServer / reboot after hours (drops 13 sessions). NEEDS approval.
+- **Share permissions work** (Howard's next focus): tighten Server/Management from
+  Authenticated Users:Full to scoped groups; stop storing admin creds on user PCs.
+- **pfSense + VLAN review** (Howard) — segment/routing design between 192.168.x and 10.0.20.x.
+- **Meredith:** buy a new wireless adapter (AC 3165 lacks WPA3); do NOT change her connection
+  until then.
+- **Testing:** use Karen's machine (DESKTOP-LPOPV30) as the mapped-drive test box.
+- Optional: restore Karen's CSC ENT if she needs NAS-by-name.
