## Current State

**Status:** ACTIVE
**Last Activity:** 2026-04-13

Music retail + repair shop running AIMsi POS on-prem. Primary server IMC1 (Dell R720, Windows Server 2016, DC for IMC.local). SQL Server 2019 Express (`IMC1\AIMSQL`). AIMsi DBs moved to dedicated SSD (`S:\SQL\Data\`). Local SQL backups running nightly; Cloudberry off-site backups configured. Known issue: component store corruption (0x80073701) blocking RDS role removal — Server 2019 migration decision pending.

## Infrastructure / Access

| Resource | Address | Notes |
|----------|---------|-------|
| IMC1 (primary server) | 192.168.0.2 | Windows Server 2016, DC (IMC.local), Dell R720 |
| SQL instance | IMC1\AIMSQL | MSSQL 2019 Express. DBs on S:\SQL\Data\ |

**SSH:** `ssh IMC\guru@192.168.0.2` (ed25519 key, PowerShell default shell)
**VPN:** OpenVPN (.ovpn profile) — disconnect Tailscale first (192.168.0.0/24 conflict)
**Domain admin:** `IMC\guru` — also SQL sysadmin (added via single-user recovery 2026-04-12)
**Credentials:** Vault entry needed (`clients/imc/` — not yet created as of 2026-04-13)

**Disks:** C: (OS, 77% full), E: (SQL backups + installers), F: (Windows Image Backups), S: (SSD — AIMsi DBs)
**Backup:** Nightly SQL at 22:00 to `E:\SQL\...\Backup\`; retention script `C:\Scripts\Clean-AimsiBackups.ps1` (14 dailies + 1st-of-month); Cloudberry at `C:\ProgramData\Online Backup\`

**Known issues:**
- Component store corrupted (0x80073701) — blocks RDS role removal; ETW manifest error on reboot
- C: drive at ~77% full — monitor
- SMB1 still enabled — disable when time permits
- `TestConv61223` DB (leftover from 2023 migration test) safe to drop — verify first

## Pending / Next Up

- [ ] Decide Server 2019 migration path (in-place upgrade vs. clean build + migrate)
- [ ] Verify Cloudberry backup continuity
- [ ] Drop `TestConv61223` DB after confirming nothing references it
- [ ] Disable SMB1 on IMC1
- [ ] Add IMC vault entry for SSH/SQL/domain credentials
- [ ] Follow up on disk management items from 2026-04-13 session
