Here’s a step-by-step guide to troubleshooting Windows installation on high-security networks:

Pre-Installation Checks

  • Network Segmentation: Ensure that the network is segmented into smaller subnets, if necessary, to isolate critical infrastructure and prevent lateral movement.

  • Firewall Rules: Review firewall rules to ensure they allow incoming connections for necessary services, such as DNS, DHCP, and remote access protocols like RDP or SSH.

  • DNS Configuration: Verify that DNS servers are configured correctly, including the IP addresses, port numbers, and record types (A, AAAA, NS, MX, PTR).

  • DHCP Server: Ensure the DHCP server is functioning properly by checking its status and configuring it to assign static leases.

Installation Troubleshooting Steps

  • Start with a Basic Install

* Run Windows Setup or Install Windows as normal.

  • Check for Network Errors

* If you encounter errors during installation, check the Event Viewer logs for specific error messages related to networking (e.g., DNS, DHCP, etc.).

* Look for any error messages indicating connectivity issues or network configuration problems.

DNS Troubleshooting

  • Verify DNS Server Configuration

* Check DNS server IP addresses and port numbers.

* Ensure that the DNS resolver is properly configured in the Windows installer.

  • Check DNS Records

* Verify that DNS records are correctly configured, including A, AAAA, NS, MX, and PTR records for all domain controllers, servers, and other critical services.

DHCP Troubleshooting

  • Verify DHCP Server Configuration

* Check DHCP server IP addresses and port numbers.

* Ensure the DHCP server is enabled and configured to assign static leases.

  • Check Lease Duration

* Verify that lease duration is set correctly for all devices connected to the network.

Remote Access Troubleshooting

  • Enable Remote Desktop Connection

* If you’re having trouble connecting to a Windows machine remotely, ensure the Remote Desktop Protocol (RDP) is enabled and configured correctly.

  • Check Firewall Rules

* Ensure that RDP traffic is allowed by reviewing firewall rules.

Additional Tips

  • Use the built-in tools like Event Viewer to monitor network activity and troubleshoot issues.

  • Consider implementing a third-party security tool, such as NSEC or Nessus, to scan for potential vulnerabilities.

  • Regularly review the Windows installation logs (Event Viewer) and DNS and DHCP configuration files for signs of tampering.

Common Issues

  • DNS and DHCP Connection Issues: Ensure that the network segment is properly isolated from each other. Check firewall rules and configure the necessary access rights.

  • Remote Access Connectivity: Verify RDP settings, including port numbers and authentication methods (e.g., username and password or smart cards).

  • Firewall Rules: Review and update firewall rules to allow necessary connections for critical services.

Common Solutions

  • DNS Issues: Restart DNS servers, check DNS resolver configuration, and verify record types.

  • DHCP Issues: Restart DHCP server, configure lease duration correctly, and ensure the network segment is isolated from other networks.

  • Remote Access Issues: Configure RDP settings, enable remote access protocols (e.g., SSH), and ensure firewall rules allow necessary connections.

Best Practices

  • Regularly review Windows installation logs to detect potential issues before they become critical.

  • Implement a patch management system to keep software up-to-date and prevent vulnerabilities.

  • Train users on network security best practices to minimize risks.
