## Key Features Implemented

### ✅ Certificate Generation
- Self-signed wildcard certificate for `*.logon.ds.ge.com`
- Alternative generation methods to avoid smart card conflicts
- 2048-bit RSA with SHA256
- Valid for 2 years (expires 2027-10-17)

### ✅ Deployment Scripts
- **Two deployment methods**:
  - `Deploy-WinRM-HTTPS.bat` - Secure (prompts for password)
  - `Deploy-WinRM-HTTPS-AutoPassword.bat` - Testing (auto-password)
- Automatic administrator privilege checking
- File validation before execution
- Execution policy bypass (`-ExecutionPolicy Bypass`)
- Network share compatible

### ✅ Comprehensive Logging
- **Log Location**: `S:\DT\ADATA\SCRIPT\DEPLOY\LOGS\`
- **Log Format**: `HOSTNAME-YYYYMMDD-HHMMSS.txt`
- **Logged Information**:
  - Deployment start/end times
  - Administrator privilege status
  - Certificate import results
  - HTTPS listener creation
  - Firewall rule configuration
  - Success/failure status
  - All error messages

### ✅ WinRM HTTPS Configuration
- Creates HTTPS listener on port 5986
- Uses wildcard certificate for all PCs
- Constructs FQDN: `hostname.logon.ds.ge.com`
- Configures firewall rule automatically
- Enables certificate authentication
- Maintains HTTP listener (port 5985)

### ✅ Testing & Validation
- Test scripts for connectivity verification
- Log viewer with filtering capabilities
- Summary report generation
- Remote connection examples

### ✅ Documentation
- Quick start guides
- Detailed deployment instructions
- Security best practices
- Troubleshooting guides

## Technical Implementation Details

### Certificate Setup
```powershell
# Certificate Subject: CN=*.logon.ds.ge.com
# Thumbprint: C1412765B2839E9081FCEA77BB1E6D8840203509 (example)
# Store Location: Cert:\LocalMachine\My
# Key Usage: Digital Signature, Key Encipherment
# Enhanced Key Usage: Server Authentication
```

### WinRM Listener Creation
Fixed implementation using `cmd.exe` to avoid PowerShell quoting issues:
```powershell
$winrmArgs = "create winrm/config/Listener?Address=*+Transport=HTTPS @{Hostname=`"$Hostname`";CertificateThumbprint=`"$thumbprint`";Port=`"$Port`"}"
$result = cmd.exe /c "winrm $winrmArgs" 2>&1
```

### Logging Implementation
Dual output to console and log file:
```powershell
function Write-ColorOutput {
    param([string]$Message, [string]$Color = "White")
    Write-Host $Message -ForegroundColor $Color

    if ($script:LogFile) {
        Add-Content -Path $script:LogFile -Value $Message -ErrorAction SilentlyContinue
    }
}
```

### Batch File Execution
```batch
PowerShell.exe -NoProfile -ExecutionPolicy Bypass -Command ^
    "$certPass = ConvertTo-SecureString '%CERT_PASSWORD%' -AsPlainText -Force; & '%SCRIPT_DIR%Setup-WinRM-HTTPS.ps1' -CertificatePath '%SCRIPT_DIR%wildcard-logon-ds-ge-com-20251017.pfx' -CertificatePassword $certPass -Domain 'logon.ds.ge.com' -LogFile '%LOG_FILE%'"
```

## Issues Resolved

### 1. Smart Card Device Error
**Problem**: Certificate generation failed with "smart card device is read-only"
**Solution**: Created alternative script using `certreq.exe` with fallback methods
**Status**: ✅ Resolved - Certificate generated successfully

### 2. LogFile Parameter Not Found
**Problem**: Batch file tried to pass `-LogFile` parameter that didn't exist
**Solution**: Added `-LogFile` parameter to `Setup-WinRM-HTTPS.ps1` param block
**Status**: ✅ Resolved - Logging now works correctly

### 3. WinRM HTTPS Listener Creation Failed (First Issue)
**Problem**: Listener creation failed due to PowerShell string escaping issues
**Solution**: Changed from `Invoke-Expression` to `cmd.exe /c` execution
**Status**: ✅ Resolved - Command execution fixed

### 4. Certificate CN Mismatch Error (Critical Fix)
**Problem**: Listener creation failed with error "The certificate CN and the hostname that were provided do not match"
**Error**: `-2144108311 (0x803380E9)`
**Root Cause**: WinRM listener hostname parameter must EXACTLY match certificate CN
- Certificate CN: `*.logon.ds.ge.com` (wildcard)
- Original approach: Used specific FQDN `g9kn7pz3esf.logon.ds.ge.com`
- Result: Mismatch error

**Solution**: Extract certificate CN and use wildcard format for listener hostname
```powershell
# Extract CN from certificate
if ($certSubject -match 'CN=([^,]+)') {
    $certCN = $matches[1]  # "*.logon.ds.ge.com"
}

# Use wildcard CN as listener hostname
$listenerHostname = $certCN  # "*.logon.ds.ge.com"
winrm create ... @{Hostname="*.logon.ds.ge.com";...}
```

**How It Works**:
- Listener configured with wildcard hostname: `*.logon.ds.ge.com`
- Clients connect using specific FQDN: `g9kn7pz3esf.logon.ds.ge.com`
- WinRM matches specific hostname against wildcard pattern
- Certificate validation succeeds for all subdomains

**Status**: ✅ Resolved - Wildcard matching now works correctly
**Documentation**: See `WILDCARD-CERT-FIX.txt` for detailed explanation

### 5. Plaintext Password in Examples
**Problem**: Security concern with plaintext passwords in documentation
**Solution**: Created `SECURE_CREDENTIAL_MANAGEMENT.md` and updated all examples
**Status**: ✅ Resolved - All examples use secure methods

## Target Systems

**Total Shopfloor PCs**: 175
**Database Query**: `pctypeid = 3` from `shopdb.pc` table
**Hostname List**: `shopfloor-hostnames.txt`

**Example Hostnames**:
- G1JJVH63ESF → g1jjvh63esf.logon.ds.ge.com
- G1JJXH63ESF → g1jjxh63esf.logon.ds.ge.com

---

## Testing Commands

### Test WinRM HTTPS Connectivity
```powershell
# From management server
Test-WSMan -ComputerName g9kn7pz3esf.logon.ds.ge.com -Port 5986 -UseSSL
```

### Create Remote Session
```powershell
# Interactive
$cred = Get-Credential
Enter-PSSession -ComputerName g9kn7pz3esf.logon.ds.ge.com `
    -Credential $cred -UseSSL -Port 5986

# Session object
$session = New-PSSession -ComputerName g9kn7pz3esf.logon.ds.ge.com `
    -Credential $cred -UseSSL -Port 5986
Invoke-Command -Session $session -ScriptBlock { Get-ComputerInfo }
```

### Verify Configuration on Target PC
```powershell
# Check WinRM listeners
winrm enumerate winrm/config/listener

# Check certificate
Get-ChildItem Cert:\LocalMachine\My |
    Where-Object {$_.Subject -like "*logon.ds.ge.com*"}

# Check firewall rule
Get-NetFirewallRule -DisplayName "WinRM HTTPS-In"

# Check WinRM service
Get-Service WinRM | Select-Object Name, Status, StartType
```

## Security Considerations

### Certificate Security
- ✅ Self-signed certificate (appropriate for internal use)
- ✅ Private key marked as exportable (for backup purposes)
- ✅ Stored in Local Machine certificate store
- ✅ 2048-bit RSA encryption
- ⚠️ Certificate password stored in deployment scripts (testing only)

### Deployment Security
- ✅ Two versions: secure (production) and auto-password (testing)
- ✅ Documentation emphasizes deleting auto-password version
- ✅ Network share requires proper permissions
- ✅ Administrator privileges required for deployment
- ✅ All examples use secure credential methods

### Credential Management
- ✅ Documented 5 secure methods in `SECURE_CREDENTIAL_MANAGEMENT.md`
- ✅ No plaintext passwords in production examples
- ✅ Recommendations for Azure Key Vault integration
- ✅ Windows Credential Manager integration documented
