Technical Implementation Details

Certificate Setup

# 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:

$winrmArgs = "create winrm/config/Listener?Address=*+Transport=HTTPS @{Hostname=`"$Hostname`";CertificateThumbprint=`"$thumbprint`";Port=`"$Port`"}"
$result = cmd.exe /c "winrm $winrmArgs" 2>&1

Logging Implementation

Dual output to console and log file:

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

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

# 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

Verify Configuration on Target PC

# 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

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
