Howard Enos 8d975c1b44 import: ingested 160 files from C:\Users\howar\Clients 
Howard's personal MSP client documentation folder imported into shared
ClaudeTools repo via /import command. Scope:

Clients (structured MSP docs under clients/<name>/docs/):
- anaise       (NEW)  - 13 files
- cascades-tucson     - 47 files merged (existing had only reports/)
- dataforth           - 18 files merged (alongside incident reports)
- instrumental-music-center - 14 files merged
- khalsa       (NEW)  - 22 files, multi-site (camden, river)
- kittle       (NEW)  - 16 files incl. fix-pdf-preview, gpo-intranet-zone
- lens-auto-brokerage (NEW) - 3 files (name matches SOPS vault)
- _client_template    - 13-file scaffold for new clients

MSP tooling (projects/msp-tools/):
- msp-audit-scripts/ - server_audit.ps1, workstation_audit.ps1, README
- utilities/         - clean_printer_ports, win11_upgrade,
                       screenconnect-toolbox-commands

Credential handling:
- Extracted 1 inline password (Anaise DESKTOP-O8GF4SD / david)
  to SOPS vault: clients/anaise/desktop-o8gf4sd.sops.yaml
- Redacted overview.md with vault reference pattern
- Scanned all 160 files for keys/tokens/connection strings -
  no other credentials found

Skipped:
- Cascades/.claude/settings.local.json (per-machine config)
- Source-root CLAUDE.md (personal, claudetools has its own)
- scripts/server_audit.ps1 and workstation_audit.ps1 at source root
  (identical duplicates of msp-audit-scripts versions)

Memory updates:
- reference_client_docs_structure.md (layout, conventions, active list)
- reference_msp_audit_scripts.md (locations, ScreenConnect 80-char rule)

  • _kerberos._tcp (Kerberos, port 88)
  • _kpasswd._tcp (Kerberos password, port 464)
  • _ldap._tcp (LDAP, port 389)
  • All registered 8/28/2024 — normal for single-DC environment

DNS Issues — Status

  1. Stale @ records — FIXED 2026-03-06. Removed old 192.168.0.5 and 192.168.2.59. Added correct 192.168.2.254.
  2. Stale computer records — FIXED 2026-03-06. Removed CRYSTAL-PC (192.168.5.115), CS-QB (192.168.5.29), DESKTOP-1ISF081 (192.168.5.30).
  3. No reverse lookup zones — FIXED 2026-03-06. Created 5 reverse zones covering LAN /22 and INTERNAL.
  4. DomainDnsZones/ForestDnsZones stale — FIXED 2026-03-06. Removed old IPs, added 192.168.2.254.

DNS Architecture (pfSense + Windows DNS)

  • pfSense Unbound (192.168.0.1): Primary DNS resolver for all clients. Forwards external queries to 8.8.8.8 / 1.1.1.1. Registers DHCP leases.
  • Windows DNS (192.168.2.254): Authoritative for cascades.local zone. Required for AD SRV records, Kerberos, LDAP lookups.
  • Forwarding relationship: Needs verification — pfSense should forward cascades.local queries to 192.168.2.254, and Windows DNS should forward external queries to pfSense or directly to internet resolvers.
  • Domain-joined PCs likely use 192.168.2.254 as DNS (per server's own config) or 192.168.0.1 (per DHCP).

Migration Plan — DNS Changes (Phase 1.4 + 2.1)

See migration/phase2-server-prep.md and migration/scripts/phase2-dns-cleanup.ps1.

pfSense Domain Overrides (Phase 1.4) — DONE 2026-03-06

Domain Forward to Purpose Status
cascades.local 192.168.2.254 AD domain resolution ✅ Added
_msdcs.cascades.local 192.168.2.254 AD metadata zone ✅ Added

CS-SERVER DNS Client Fix (Phase 1.4) — DONE 2026-03-06

CS-SERVER used pfSense (192.168.0.1) + 8.8.8.8 as DNS. Fixed: now uses 127.0.0.1, 192.168.0.1. Verified — both cs-server.cascades.local and google.com resolve correctly through localhost.

CS-SERVER Forwarder Fix (Phase 1.4)

Set Windows DNS forwarder to 192.168.0.1 (pfSense) for external resolution. TODO: Verify this is set.

Stale Record Cleanup (Phase 2.1) — DONE 2026-03-06

All stale records removed and correct records added:

  • cascades.local @ → 192.168.0.5, 192.168.2.59 Removed. Added correct: @ → 192.168.2.254
  • CRYSTAL-PC → 192.168.5.115 Removed (will re-register correct IP via DHCP)
  • CS-QB → 192.168.5.29 Removed (will re-register correct IP via DHCP)
  • DESKTOP-1ISF081 → 192.168.5.30 Removed
  • DomainDnsZones → 192.168.0.5, 192.168.2.59 Removed. Added correct: → 192.168.2.254
  • ForestDnsZones → 192.168.0.5, 192.168.2.59 Removed. Added correct: → 192.168.2.254

Enable Scavenging (Phase 2.1) — DONE 2026-03-06

  • Server-level scavenging: enabled, 7-day interval ✅
  • Zone aging on cascades.local: enabled ✅
  • First scavenge available: 3/13/2026 (14-day aging window from enable date)

Create Reverse Lookup Zones (Phase 2.1) — DONE 2026-03-06

All 5 reverse zones created (AD-integrated, Domain replication scope):

  • 0.168.192.in-addr.arpa ✅
  • 1.168.192.in-addr.arpa ✅
  • 2.168.192.in-addr.arpa ✅
  • 3.168.192.in-addr.arpa ✅
  • 20.0.10.in-addr.arpa ✅

External DNS

  • Not documented yet (registrar, hosted DNS, etc.)

Notes

  • pfSense Unbound serves as the DNS resolver for all VLANs
  • Room VLANs use their gateway (pfSense interface IP) as DNS server
  • INTERNAL VLAN uses 192.168.0.1 explicitly as DNS
  • 999GuruTestNet uses 10.0.99.1 as DNS
