+# Windows OpenSSH Server (sshd) Stops After Reboot
+
+## 🛑 Problem
+
+SSH connections to MajorRig from a mobile device or Tailscale client time out on port 22. No connection refused error — just a timeout. The OpenSSH Server service is installed but not running.
+
+---
+
+## 🔍 Diagnosis
+
+From an **elevated** PowerShell on MajorRig:
+
+```powershell
+Get-Service sshd
+```
+
+If the output shows `Stopped`, the service is not running. This is the cause of the timeout.
+
+---
+
+## ✅ Fix
+
+Run the following from an **elevated** PowerShell (Win+X → Terminal (Admin)):
+
+```powershell
+Start-Service sshd
+Set-Service -Name sshd -StartupType Automatic
+Get-Service sshd
+```
+
+The final command should confirm `Running`. SSH connections will resume immediately — no reboot required.
+
+---
+
+## 🔄 Why This Happens
+
+| Trigger | Reason |
+|---|---|
+| Windows Update reboot | If `sshd` startup type is Manual, it won't restart after a reboot |
+| WSL2 export/import/rebuild | WSL2 reinstall operations often involve reboots that expose the same issue |
+| Fresh Windows install | OpenSSH Server is installed but startup type defaults to Manual |
+
+The Windows OpenSSH Server is installed as a Windows Feature (`Add-WindowsCapability`), not a WSL2 package. It runs entirely on the Windows side. However, its **default startup type is Manual**, meaning it will not survive a reboot unless explicitly set to Automatic.
+
+---
+
+## ⚠️ Key Notes
+
+- **This is a Windows-side issue** — WSL2 itself is unaffected. The service must be started and configured from Windows, not from within WSL2.
+- **Elevated PowerShell required** — `Start-Service` and `Set-Service` for sshd will return "Access is denied" if run without Administrator privileges.
+- **Port 2222 is also affected** — both the standard port 22 and the bypass port 2222 on MajorRig are served by the same `sshd` service.
+- **Default shell still works once fixed** — MajorRig's sshd is configured to use `C:\Windows\System32\wsl.exe` as the default shell, dropping SSH sessions directly into WSL2/Bash. This config is preserved across service restarts.

+
+## 🔎 Quick Reference
+
+```powershell
+# Check status (run as Admin)
+Get-Service sshd
+
+# Start and set to auto-start (run as Admin)
+Start-Service sshd
+Set-Service -Name sshd -StartupType Automatic
+
+# Verify firewall rule exists
+Get-NetFirewallRule -DisplayName "*ssh*" | Select DisplayName, Enabled, Direction, Action
+```
